[1] This application has priority over U.S. Provisional Patent Application. provisional patent application 61 / 534,359, registered September 13, 2011, is fully incorporated by reference.

FIELD OF THE INVENTION

[2] The invention relates to drillstrings for drilling rigs.

BACKGROUND OF THE INVENTION

[3] Drilling rigs are often used in the construction, mining and oil and gas industries to make a wellbore passing through a rock using a drill string. There are many different types of drilling rigs for drilling a borehole through a rock using a drill string. Some of these drilling rigs are mobile, others are stationary. Examples of mobile and stationary drilling rigs are disclosed in U.S. patents. patent No. 3,245,180, 3,692,123, 3,708,024, 3,778,940, 3,815,690, 3,833,072, 3,905,168, 3,968,845, 3,992,831, 4,020,909, 4,295,758, 4,595,065, 5,988,299, 6,672,410, 6,675,915, 7,325,634, 7,325,634 included.

[4] One of the drilling rigs includes a platform supported by a platform, and a top drive moving along the tower. A drilling rig typically includes a liner passing through a platform. Further information on platform inserts can be found in U.S. patents. Patent Nos. 4,943,302 and 5,413,415, as well as U.S. Patent Application. Patent Application No. 20030155769, fully incorporated by reference in this document.

[5] A drill string typically includes one or more drill pipes, and each drill pipe includes a pipe body connected to a drill joint. The drill string provides a borehole with a depth greater than the length of one pipe body. The pipe body typically has a length of from about 20 feet (6 m) to about 40 feet (12 m). Most drill pipe bodies are made from thick-walled steel pipes. Various types of steel can be used, for example, mild low carbon steel or other steel alloys. Further information on drill strings and drill pipe tool joints can be found in U.S. Patents. Patent Nos. 4,279,850, 4,380,347, 4,487,229, 4,492,666, and 5,709,416 are fully incorporated by reference herein.

[6] In a conventional design, plug-in and female drill joints are installed at opposite ends of the pipe body, wherein the drill-pipe insert lock includes a threaded lock nipple and the drill pipe female lock includes a threaded lock sleeve. It should be noted, however, that some drill pipes include plug-in drill joints at opposite ends, and other drill pipes include female drill joints at opposite ends. The types of drill pipe locks installed on opposite ends of the pipe body depend on many different factors, such as the type of drilling machine used to make the wellbore, as well as the application for drilling.

[7] Drill locks are usually made of metal, such as steel or precision machined steel alloy. Drill locks can be integral parts of the pipe body, or they can be separate parts that can be connected to it repeatedly. For example, plug-in and female tool joints can be welded to the pipe body and can be replaced repeatedly using welding.

[8] In one example, a threaded joint nipple is screwed into a threaded joint of a second drill pipe, and a threaded joint of a first drill pipe is threaded to a threaded joint of a third drill pipe. Thus, the first, second and third drill pipes are connected together.

[9] In some examples, the threads of both the nipple and the coupling are right, and in other examples, the threads of both the nipple and the coupling are left. Further information on right and left threads can be found in U.S. Patents. Patent Nos. 1,769,381, 3,186,501, 3,645,328 and 4,422,507 are fully incorporated by reference herein. Further information on right and left threads can also be found in some of the other materials mentioned in this document.

[10] When performing work, the drill string is connected to the top drive and extends through the insert in the platform. The drill string moves relative to the tower in response to the movement of the top drive. One of the drill pipe of the drill string is functionally connected to an earth chisel. The drill string provides fluid to the soil bit to allow for rock drilling. Thus, the drill string includes drill pipes with the possibility of functional connection with the soil bit. The wellbore is formed as a result of rotation of the drill string and soil bit by the top drive, and feeding them down through the liner in the platform into the formation with a load applied by the top drive. Thus, the drill string not only transfers torque, feed and lift force from the top drive of the drilling rig to the drill bit, but also provides its own extension along the entire length to the design drilling depth.

[11] Drillstrings are consumable components because they undergo significant wear during use. In most cases, the drill pipe lock is subject to wear and tear, while the pipe body remains usable. In these situations, the drill pipe is removed from the drill string and the drill pipe lock is replaced with another lock. In other situations, the drill pipe is removed from the drill string and the drill pipe lock is repaired to continue using it.

[12] However, replacing a drill pipe lock at a drilling site is very time consuming, and repairing a drill pipe lock at a drilling site is expensive. Drilling sites are usually remote and do not have the necessary equipment, resources and technical personnel. Therefore, the drill pipe and drill lock are usually delivered to a machine shop in which highly qualified technicians can remove the lock from the drill pipe and replace it with another lock, or repair the drill pipe lock. The components are then sent back to the remote site. However, such transportation and repair of the drill pipe and drill pipe lock is time consuming, expensive and creates environmental problems due to fuel consumption for transportation.

In FIG. 17 shows a portion of a replaceable nipple end of a drill string lock.

In FIG. 17a shows a semicircular groove on an interchangeable drill pipe tool nipple.

[52] The invention relates to a tool assembly of drill pipes, which includes interchangeable drill joints. Replaceable drill joints can include a drill lock adapter that connects to the pipe body, and drill locks that connect to a drill lock adapter using a faceted nipple. A faceted nipple may include a faceted connecting pipe having a connecting surface. The layout of the tool generally includes a locking pin that passes through the drill lock adapter and a drill lock, with the locking pin passing through a groove under the locking pin of the connecting face. The locking pin can lock the drill lock adapter with the drill lock. The locking pin may be removed from the groove under the locking pin so that the drill lock adapter and drill lock are unlocked. In this case, the drill pipe lock is a replaceable drill lock.

[53] The drill collar adapter and drill collar can both be included in the drill string, in this document the first and second drill pipes can be detachably connected to the drill collar adapter and drill collar, respectively. The drill string can be used by a drilling rig for drilling in rock.

[54] As mentioned above, drill strings are consumable components because they undergo significant wear during operation. Embodiments of the invention provide for simple removal of a drill pipe lock in a drill string and its replacement. In this case, the drill string can be repaired at the work site and it is not necessary to send the drill string to a mechanical workshop for repair, and then transported back to the work site.

[55] A drill pipe tool arrangement can be used with many different types of drilling rigs, for example, rotary blasthole drilling rigs used in the opencast coal industry. A drill pipe tool arrangement is useful for many different drilling applications, such as single pass drilling and multiple soft rock passes.

[56] The drill pipe tool assembly disclosed herein can be used for rotary drilling of blast holes used in open pit coal mines, where the rock is usually relatively soft. Compared to drilling in hard rock conditions, the pipe body can work much longer in the application for soft rocks, since there is very little external wear on the body of the drill pipe.

[57] However, in any situation, the threads at both ends of the drill pipe are subject to wear because the drill pipe needs to be permanently fastened and unfastened during normal drilling operations. To increase the service life and reduce the cost of drilling, in most existing options, worn drill pipes are sent to a specialized workshop for repair, while the main body of the pipe has a satisfactory condition and can be reused. Instead of transporting the drill pipe back and forth, the invention allows the user to restore the drill pipe to a remote drilling site.

[58] In FIG. 1a shows a side view of a drilling rig 300. It should be noted that the drilling rig 300 may be stationary or mobile, here a mobile installation is shown for illustration. Some examples of drilling rigs of various types are DM-M3, PV-235, PV-270, PV-271, PV-275 and PV-351 drilling rigs, manufactured by Atlas Copco Drilling Solutions, Garland, Texas. It should be noted, however, that drilling rigs are produced by many other manufacturers.

[59] In this embodiment, the drilling rig 300 includes a platform 303 that carries a power unit 304 and an operator cabin 305. It should be noted that the power unit 304 includes many different components, such as the main engine, and is usually controlled by the operator in the operator's cabin 305.

[60] In this embodiment, the drilling rig 300 includes a tower 302 that rests on a platform 303. The tower 302 is usually equipped with a cable feed system (not shown) connected to the top drive 307, here the cable feed system allows the top drive 307 to be lowered and raised between an upper and lower position along the tower 302. A cable feed system moves the top drive 307 between the upper and lower positions, moving it to the crown block 302b and the tower base 302a, respectively.

[61] The top drive 307 moves between the upper and lower positions, raising and lowering, respectively, the drill string 100 in the wellbore. In addition, the top drive 307 is used to rotate the drill string 100, with the drill string 100 passing through the tower 302 and platform 303. The drill string 100 typically includes one or more drill pipes connected in a well-known manner. The drill pipe of the drill string 100 is configured to be connected to a ground bit, such as a three-cone rotary ground bit. In FIG. 1a illustrates a drill string 100 including drill pipes 110 and 120.

[62] In FIG. 1b shows an isometric view of a drill string 100, which includes drill pipes 110 and 120 connected at a joint 101 of drill pipes. In FIG. 1c shows a longitudinal section of the drill string 100 in the joint area 102 shown in FIG. 1b, here, the joint zone 102 includes a drill pipe joint 101. The drill string 100, as well as the drill pipes 110 and 120, have a longitudinal direction 105 and a transverse direction 106, directions 105 and 106 are perpendicular to each other. It should be noted that the direction 106 in some cases is called the radial direction. Zone 109 is external to the drill string 100. The drill string 100 includes a nipple zone 103 at one end and a coupling zone 104 at the opposite end.

[63] In this embodiment, the drill pipe 110 includes a pipe body 111 with an internal pipe passage 112 through it, as shown in FIG. 1c. The drill pipe 110 includes a threaded locking nipple 119, which includes a threaded portion 113 with a threaded nipple 114. The inner pipe channel 112 passes through the pipe body 111 and the threaded portion 113, and provides a through passage of material through it. The inner pipe channel 112 extends longitudinally in the longitudinal direction 105 and transversely in the transverse direction 106. The threaded locking nipple 119 may be an integral part of the pipe body 111, or may be a separate part that is connected to it in a manner involving repeated replacement. In some embodiments, a threaded locking nipple 119 is welded to the pipe body 111.

[64] In this embodiment, the drill pipe 120 includes a pipe body 121 with an inner pipe passage 122 extending therethrough as shown in FIG. 1c. In this embodiment, drill pipe 120 includes a threaded locking sleeve 123 (FIG. 1c), which includes a coupling thread 124. The threaded lock sleeve 123 is screwed onto the threaded lock nipple 119 by connecting the drill pipe 110 and 120 together. In particular, the nipple thread 114 and the coupling thread 124 are screwed together when the drill pipes 110 and 120 are connected to each other. The inner channel 122 of the drill pipe passes through the body 121 of the pipe and the locking sleeve 123 and provides a through passage of material through it. The inner channel 122 of the drill pipe extends longitudinally in the longitudinal direction 105, and transversely in the transverse direction 106. The threaded joint sleeve 123 may be an integral part of the pipe body 121, or a separate part that is connected to it in a manner that allows multiple replacement. In some embodiments, a threaded lock sleeve 123 is welded to the pipe body 121.

[65] It should be noted that in some embodiments, both the threaded locking nipple 119 and the threaded locking sleeve 123 have a right-handed thread. In right-handed embodiments, both the nipple thread 114 and the coupling thread 124 are right-handed threads. In other embodiments, both threaded locking nipple 119 and threaded locking sleeve 123 have left-hand threads. In left-handed embodiments, both the nipple thread 114 and the coupling thread 124 are left-handed.

[66] In FIG. 1d shows an isometric view of a drill string 100 that includes interchangeable drill joints. In this embodiment, the drill string 100 includes a drill pipe tool nipple 170 connected to one end of the drill pipe 120 in the coupling zone 104, and a drill pipe drill collar 150 connected to one end of the drill pipe 110 in the nipple zone 103. In this embodiment, the drill string 100 includes plug-in and female tool joints at opposite ends, and can operate with an Atlas Copco DM-M3 drilling rig, which is used for blast hole drilling.

[67] In FIG. 1e shows an exploded embodiment of the drill string 100 in the nipple zone 103 of FIG. 1d. In this embodiment, the drill string 100 includes a drill lock adapter 130a connecting to the drill rod body 111. The drill lock adapter 130a can connect to the drill rod body 111 in many different ways. In this embodiment, the drill joint adapter 130a is connected to the drill rod body 111 in a welded manner that allows multiple replacements.

[68] In this embodiment, the drill string 100 includes a drill pipe tool sleeve 150 that connects to the drill lock adapter 130a. The drill collar 150 can be connected to the drill collar adapter 130a in many different ways. In this embodiment, the drill collar 150 is connected to the drill adapter 130 a in a multiple-exchange manner using locking pins 270a and 270b, which are discussed in more detail below. The locking pins 270a and 270b are held in place using fasteners 271a and 271b, respectively. A seal is created between the drill pipe tool joint 150 and the drill tool adapter 130a, since the tool pipe tool 150 and the tool adapter 130a are connected through the sealing members 272a and 273a.

[69] In FIG. 1f shows the exploded drill string 100 in the coupling zone 104 of FIG. 1d. In this embodiment, the drill string 100 includes a drill lock adapter 130b connecting to the body 121 of the rod 120. The drill lock adapter 130b may be connected to the body 121 of the drill rod in many different ways. In this embodiment, the drill-lock adapter 130b is connected to the rod body 121 in a multiple-exchange manner using welding.

[70] In this embodiment, the drill string 100 includes a drill pipe tool nipple 170 connected to a drill lock adapter 130b. The drill pipe tool nipple 170 can be connected to the drill tool adapter 130b in many different ways. In this embodiment, the drill pipe tool nipple 170 is connected to the drill tool adapter 130b in a multiple exchange manner using the locking pins 270c and 270d, which are discussed in more detail below. The locking pins 270c and 270d are held in place using fasteners 271c and 271d, respectively. A seal is created between the drill pipe key lock 170 and the drill joint adapter 130b, since the drill pipe joint 170 and the drill joint adapter 130b are connected through the sealing members 272b and 273b.

[71] The drill string 100 includes three main sections, including a replaceable drill pipe tool nipple, an assembly of the main body of the pipe and a replaceable drill pipe tool sleeve. The layout of the main body of the pipe is composed of the main body of the pipe and two adapters of the drill joint. Two drill joint adapters are tightened and welded at both ends of the main body of the pipe. Instead of welding on the main drill pipe, both the interchangeable drill pipe tool nipple and the replaceable drill pipe tool joint are fixed on the main body of the pipe with locking pins. For example, in this embodiment, the drill joints are connected to the corresponding body of the drill pipe by locking pins 270a, 270b, 270c and 270d. Torque is transmitted throughout the drill string 100 by a polygonal paired element, which also precisely controls the combination of turn-key sections on the locks of both ends of the drill pipe. The lock adapter is welded into the main body of the pipe. The end user can generally replace the drill pipe lock when required, without the need to remove the drill lock adapter on the job site.

[72] In general, a drill pipe lock is a threaded joint at the ends of a drill pipe. To obtain a continuous connection in the drill string, the drill pipe lock is screwed onto one of the two ends. A drill pipe lock with a threaded thread is also called a drill pipe tool nipple, and a female drill pipe lock is called a drill pipe tool sleeve. Based on the actual drilling requirements, the drill joints can have various combinations, for example, drill pipe tool nipple and drill pipe tool sleeve, drill pipe tool nipple and tool pipe lock, or drill pipe tool coupler and drill pipe tool coupler.

[73] Accordingly, drill pipe tool joints 100 can also have one of combinations, for example, a replaceable drill pipe tool nipple and a replaceable drill pipe tool joint, a replaceable drill pipe tool nipple and a replaceable drill pipe tool nipple, or a replaceable drill pipe tool lock and interchangeable drill pipe tool joint.

[74] The drill string 100 is compatible with a standard drill pipe operating on a drilling rig. With the exception of the method of connecting drill pipe locks, all other important features of the drill pipe, such as the dimensions and types of thread of the drill pipe locks, the outer diameters of the drill pipe, the distance between the steps, turnkey cuts, recesses, etc., remain unchanged. In addition, the drill string 100 is configured to withstand volumes and pressure of compressed air, torque, feed loads and lift loads are the same as standard drill strings.

[75] Compared to the known drill strings, the tool assembly of the drill pipe of the drill string 100 has been added with a drill lock adapter. One end of the drill joint adapter is machined according to standard welding specifications, such as those developed by Atlas Copco Thiessen. The opposite end is in the form of a polygonal plug-in connection with a protruding sealing cylinder. A polygonal plug-in connection transmits torque to a pair of interchangeable drill pipe tool joints that has a polygonal female connection, respectively. A theoretically accurate working fit is designed for paired polygon features. The above not only provides easy assembly and disassembly of the interchangeable drill pipe tool nipple, but also reduces runout between the drill pipe tool nipple and the corresponding drill tool adapter.

[76] A drill joint adapter may include other polygonal shapes, such as a tetrahedron, pentahedron, hexagon, etc., which can also be used to adapt to various sizes of drill pipes. At the same time, the geometrical polyhedron in such a drill pipe for an interchangeable drill pipe tool nipple and a drill lock adapter must be joined to create a satisfactory fit.

[77] As mentioned above, two drill joint adapters are tightened and welded into each end of the main body of the pipe. During welding, the welder must make sure that the set of faces of the polyhedron on the drill pipe lock adapter is aligned with the set of faces of the polyhedron on the opposite drill pipe lock adapter of the entire layout of the main body of the pipe. The above provides the welder with the assembly of the drill pipe with the correct orientation of the turn-key sections from one end of the drill string to the opposite end of the drill string.

[78] In a typical application for rotary blast hole drilling, drill string 100 is hollow to supply compressed gas through the drill string. Compressed gas can be used to cool the drill bit and blow the cuttings out of the wellbore. It is important to reduce the likelihood of unwanted gas leakage through the drill string 100. To reduce the likelihood of unwanted gas leakage, the sealing elements 272a, 272b, 273a and 273b may be included in the drill string 100, as shown in FIG. 1e and 1f. Sealing elements 272a, 272b, 273a and 273b may be, for example, various types of circular gaskets. The sealing member typically includes a deformable material, such as rubber. As discussed in more detail below, the sealing element can interact with the polygonal plug-in connection of the drill lock adapter, and it is possible to isolate compressed air coming out of both the holes for the locking pins and pair of ledges between the replaceable drill pipe lock nipple and the drill lock adapter.

[79] In FIG. 2a is an enlarged isometric view of an embodiment of a drill pipe 110 that includes a threaded locking nipple 119, and FIG. 2b is a longitudinal sectional view of an embodiment of drill pipe 110 along line 2b-2b of FIG. 2a. It should be noted that the cross-section line 2b-2b runs in the transverse direction 106. In this embodiment, a threaded locking nipple 119 includes a nipple cylinder 115 that extends from the nipple shoulder 116 and a threaded portion 113 that includes a nipple thread 114 . According to this embodiment, the nipple cylinder 115 is located near the nipple shoulder 116, and the threaded portion 113 is located at a distance from the nipple shoulder 116. The threaded portion 113 is spaced apart with a step 116 of the nipple by the cylinder 115 of the nipple. The cylinder 115 of the nipple is located between the threaded section 113 and the ledge 116 of the nipple. In an embodiment, the nipple cylinder 115 is a connecting pipe without faces because it includes a curved surface of continuous curvature and does not include a flat face interrupting the curvature. The nipple cylinder 115 passes through a threaded lock sleeve of another drill pipe, for example, drill pipe 120, when the nipple cylinder is connected to the drill pipe 110. It should be noted that the drill pipe 110 includes a threaded lock sleeve at its opposite end in the coupling region 104 as shown in FIG. 1b. It should also be noted that a threaded locking nipple 119 can generally be repeatedly removed from the pipe body 111. However, it is usually difficult to remove the locking nipple 119 with a thread from the pipe body 111, since the locking nipple with a thread is often welded in place and specialized tools are required to remove it. These specialized tools are often not available at remote drilling sites. The nipple cylinder 115 is a threaded portion without a threaded locking nipple 119. Thus, shown in FIG. 2a, threaded locking nipple 119 includes threaded portions and non-threaded portions.

[80] As shown in FIG. 2b, the pipe body 111 includes an internal pipe channel 112 that passes through it. The outer size of the body 111 of the pipe is indicated as the distance d1. The distance d1 is the transverse distance that extends in the transverse direction 106 between the center of the pipe body 111 and the outer periphery of the pipe body 111. In this embodiment, the distance d1 corresponds to the diameter of the pipe body 111 because the pipe body 111 has a circular cross section, as shown in FIG. 2b.

[81] In FIG. 3a is an enlarged isometric view of a threaded drill collar 123 with a threaded drill pipe 120, and FIG. 3b shows a cross section of the drill pipe 120 along line 3b-3b of FIG. 3a. It should be noted that the line 3b-3b runs in the transverse direction 106. It should also be noted that the drill pipe 120 includes a locking nipple with a thread at its opposite end in the nipple zone 103, as shown in FIG. 1b. Additionally, a threaded lock sleeve 123 can be repeatedly removed from the pipe body 121. However, it is usually difficult to remove the lock sleeve 123 with thread from the pipe body 121, since the lock sleeve with thread is often welded in place and specialized tools are required to remove it. As mentioned above, these specialized tools are often not available at remote drilling sites.

[82] As shown in FIG. 3b, the pipe body 121 includes an inner channel 122 of a drill pipe that passes through it. The thread 124 of the sleeve faces the inner channel 122 of the drill pipe, and the internal channel 122 of the drill pipe passes through the threaded joint sleeve 123. The drill pipe inner passage 122 allows material to pass through a threaded locking sleeve 123. The outer size of the body 121 of the pipe is indicated as the distance d2. The distance d2 is the transverse distance in the transverse direction 106 between the center of the pipe body 121 and the outer periphery of the pipe body 121. In this embodiment, the distance d2 corresponds to the diameter of the pipe body 121 because the pipe body 121 has a circular cross section, as shown in FIG. 3b.

[83] In FIG. 4a and 4c are an isometric illustration of a drilllock adapter 130, and FIG. 4b and 4d show end views of the drill joint adapter 130 facing in opposite directions, positions 139a and 139b, respectively. In this embodiment, the drill lock adapter 130 includes a drill lock adapter housing 131 with a drill hole adapter inner passage 132 passing therethrough. The drillhole adapter inner passage 132 allows material to pass through the drilllock adapter housing 131.

[84] The drill lock adapter 130 may include a drill lock adapter connection pipe 134, which may extend from a shoulder 133 of the connection pipe. The drill pipe adapter connector 134 may be sized and shaped to be received in the pipe body, for example pipe body 111 and 121. The drill pipe adapter connector 134 may have no edges and may include a curved surface with continuous curvature, and may not include a flat surface that interrupts the curvature. It should be noted that the inner channel 132 of the adapter of the drill joint passes through the connecting pipe 134 of the adapter of the drill joint and allows the passage of material through it.

[85] A drill pipe adapter connecting pipe 134 may be received into the pipe body after removing a threaded lock sleeve or threaded lock nipple from it. In some embodiments, the drill adapter 130 is welded to the pipe body. It should be noted that the adapter 130 of the drill lock is usually repeatedly removed from the body of the pipe. In this way, threaded locking nipple 119 can be removed from the pipe body and replaced with a drill lock adapter 130. Additionally, a threaded lock sleeve 123 can be removed from the pipe body and replaced with another drill lock adapter 130. However, as mentioned above, it is usually difficult to remove these components from the pipe body at a remote site, since specialized tools are required.

[86] As best shown in FIG. 4c and 4d, the drill lock adapter 130 may include a faceted socket 140, which may include in the surface of the socket. In this embodiment, the faceted nest 140 includes opposite nesting faces 141 and 142, opposite nesting faces 143 and 144, opposite nesting faces 145 and 146, and opposite nesting faces 147 and 148. The faces 141, 142, 143, 144, 145, 146, 147, and 148 of the socket can pass through the annular surface 149 of the socket and face the inner channel 132 of the drill lock adapter. The annular surface 149 of the socket may be located against the ledge 133 of the connecting pipe. In this way, the faceted socket 140 faces the inner channel 132 of the drill joint adapter, and the inner channel 132 of the adapter of the drill joint can pass through the faceted socket 140 and the surface 149 of the socket. The inner channel 132 of the adapter of the drill lock can pass through a faceted socket 140 and allow passage of material through it.

[87] It should also be noted that the faceted socket 140 includes eight flat faces of the socket in this illustrative embodiment. However, typically a faceted nest 140 includes one or more flat faces of the nest. Embodiments of sockets that include one and two facets of the socket are shown in FIG. 16a and 16b, respectively. It should be noted that nest 140 is a faceted nest, since it includes two faces with intermittent curvature between them, which is discussed in more detail here, and does not include a curved surface of continuous curvature.

[88] In this embodiment, the socket faces 141 and 143 are angled relative to each other so that the curvature of the faceted socket 140 is interrupted between them. Socket faces 143 and 145 are angled relative to each other, so that the curvature of the faceted socket 140 is interrupted between them. The faces 145 and 147 of the nest are angled relative to each other, so that the curvature of the faceted nest 140 is interrupted between them. Socket faces 147 and 142 are angled relative to each other so that the curvature of the faceted socket 140 is interrupted between them. The faces 142 and 144 of the nest are angled relative to each other, so that the curvature of the faceted nest 140 is interrupted between them. The faces 144 and 146 of the nest are angled relative to each other, so that the curvature of the faceted nest 140 is interrupted between them. The faces 146 and 148 of the nest are angled relative to each other, so that the curvature of the faceted nest 140 is interrupted between them. Thus, nest 140 is a faceted nest. Other configurations are also possible.

[89] In this embodiment, the drill lock adapter 130 includes an internal hole for the locking pins that extends through the drill lock adapter housing 131. Typically, the drill lock adapter 130 includes one or more internal holes for the locking pins. In this embodiment, the drill adapter 130 includes two internal holes for the locking pins, which are designated as internal holes 135a and 135b of the locking pins, as shown in FIG. 4d. In this embodiment, the inner holes 135a and 135b of the locking pins are located opposite to each other, while the inner holes 135a and 135b of the locking pins are located near the faces 141 and 142 of the socket, respectively. In particular, the inner holes 135a and 135b of the locking pins pass through the edges 141 and 142 of the socket, respectively. The inner holes 135a and 135b of the locking pins open into the inner channel 132 of the drill adapter.

[90] In this embodiment, the locking pin inner hole 135a includes opposing locking pin hole openings 137a and 138a, and a fastener opening 136a that extends through the drill joint adapter body 131 and the locking pin internal hole 135a. In particular, according to this embodiment, the fastener opening 136a extends between the outer periphery of the drill joint adapter housing 131 and the socket face 141. It should be noted that the portion of the inner hole 135a for the locking pin near the opening 136a of the fastener faces the inner channel 132 of the adapter of the drill joint. The portion of the inner hole 135a for the locking pin facing the opening 136a of the fastener opens into the inner channel 132 of the adapter of the drill joint.

[91] In this embodiment, the locking pin inner hole 135b includes opposing locking pin hole openings 137b and 138b, and a fastening opening 136b that extends through the drill joint adapter body 131 and the locking pin internal hole 135b. In particular, the fastener opening 136b extends between the outer periphery of the drill lock adapter housing 131 and the socket face 142. It should be noted that the portion of the inner hole 135b for the locking pin near the opening 136b of the fastener faces the inner channel 132 of the adapter of the drill lock. A portion of the inner pin 135b for the locking pin facing the fastener opening 136b opens into the inner channel 132 of the drill joint adapter.

[92] In FIG. 4e shows a cross section of a drilllock adapter 130 of FIG. 4a-4d along a line that passes through the inner holes 135a and 135b of the locking pins. The section plane extends along the axial lines of the locking pins 270a and 270b, while the locking pins 270a and 270b pass through the inner holes 135a and 135b of the locking pins, respectively. In this embodiment, the internal holes of the locking pins 135a and 135b each include crescent-shaped grooves that are sized and shaped to receive respective locking pins 270a and 270b. The inner holes 135a and 135b of the locking pins are milled passing through flat portions of the multi-faceted push-in connection. Accordingly, the crescent-shaped grooves on the interchangeable drill pipe tool nipple are drilled and cut from the outer housing of the drill pipe lock.

[93] One useful feature of this design is that the locking pins 270a and 270b are secured in place while drilling. This is useful because it is undesirable to free the locking pin during drilling operations because the portion of the drill string 100 is disconnected in the wellbore. Removing such a section of the drill string from the wellbore is expensive and time consuming.

[94] The locking pins 270a and 270b can be secured in many different ways. For example, in some embodiments, the locking pins and the holes for the locking pins are machined, as a result of which one end becomes smaller than the opposite end. The specified provides the insertion and removal of the locking pins from only one enlarged end of the hole for the locking pin.

[95] In some embodiments, when the locking pins are installed in place, the self-locking set screws are brought into contact in the middle drilled and threaded holes of the drill collar and are tightened. This element holds the locking pin from spontaneous disconnection with the exit through the enlarged side of its hole. In addition, self-locking setscrews can prevent self-locking that can cause vibration during drilling. For example, you can use set screws with pre-fabricated nylon inserts. If the locking pin is not fixed, it may fall out of the tool assembly from the drill pipe and cause a very serious accident. Many self-locking set screws of various types, for example with chemical additives, deflected or deformed threads, and additive materials, are suitable for fastening the locking pins.

[96] During drilling in the normal clockwise direction indicated in FIG. 4e, a useful constructive solution prevents the creation of additional force pushing the locking pins, the enlarged hole for the locking pin always rotates in front of the reduced hole for the locking pin, while the locking pin is pressed against the installation site.

[97] In addition to the optimal design solution of the locking pin described above, there are various ways of securing the interchangeable drill pipe tool nipple to the drill adapter. The cylinder diameter of the locking pin may be constant from one end to the other end. The hole for holding the locking pin may be of the same size over its entire depth or may undergo machining, as a result of which one end becomes smaller than the opposite end. As another example, you can install a tapering pin passing through the corresponding tapering hole, which is composed of a tapering groove on the polygonal plug-in connection of the drill adapter and a tapering groove on a pair of interchangeable drill pipe tool joints.

[98] In FIG. 5a and 5b, an isometric embodiment of a drill collar 150 is shown. In this embodiment, the drill pipe tool joint 150 includes a tool case 151 with an internal channel 152 of the tool coupler passing therethrough. The drill pipe drill collar 150 includes a drill collar 153 with a thread 154 at one end and a faceted nipple 158 at the opposite end. The thread 154 of the clutch faces the inner channel 152 of the lock clutch. It should be noted that the inner channel 152 of the lock clutch passes through the lock clutch 153 with a thread and a faceted nipple 158, and allows the passage of material through it.

[99] In this embodiment, the faceted nipple 158 includes a faceted connecting pipe that extends outward from the shoulder 157 of the nipple. Faceted nipple 158 may include a sealing nipple 155, while a faceted connecting pipe is installed near the shoulder 157 of the nipple and the sealing nipple 155 is installed at a distance from the shoulder 157 of the nipple. The sealing nipple 155 may be spaced apart from the nipple step 157 by the faceted connecting pipe 160. The faceted connecting pipe may be located between the nipple ledge 157 and the sealing nipple 155. It should be noted that the nipple ledge 157 can face the faceted connecting pipe 160 and the sealing nipple 155, and can be turned from the lock clutch 153 with a thread. It should also be noted that the inner channel 152 of the lock clutch can pass through a faceted connecting pipe and a sealing nipple 155.

[100] The nipple 155 may be a sealing nipple, as it may form a seal with other components, as discussed in more detail below. In this embodiment, the sealing nipple 155 includes a sealing groove extending by a ring around it. The sealing groove may receive a sealing element, such as an O-ring, wherein the sealing element forms a seal with another component. Thus, the nipple 155 may be a sealing nipple. In this embodiment, the sealing nipple 155 includes two sealing grooves, designated as sealing grooves 156a and 156b. In general, the drill pipe seal nipple 155 includes one or more sealing grooves.

[101] The connecting pipe 160 may be a faceted connecting pipe, because it may include a face with discontinuous curvature, and may not include a curved surface with continuous curvature, as discussed in more detail here. The faceted connecting pipe may include a connecting surface. In this embodiment, the faceted connecting pipe includes opposing edges 161 and 162 of the connecting pipe, opposite edges 163 and 164 of the connecting pipe, opposite edges 165 and 166 of the connecting pipe, and opposite faces 167 and 168 of the connecting pipe. It should be noted that the faceted connecting pipe includes eight faces as an illustration in this embodiment.

However, in general, a faceted connecting pipe includes one or more faces. The number of faces of the connecting pipe 160 corresponds to the number of faces of the socket 140 for receiving faceted socket 140 faceted connecting pipe 160.

[102] It should also be noted that the faces 161 and 163 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 163 and 165 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 165 and 167 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 167 and 162 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 162 and 164 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 164 and 166 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. The faces 166 and 168 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 160 is interrupted between them. Thus, the connecting pipe may be a faceted connecting pipe.

[103] In this embodiment, the drill pipe drill collar 150 includes a locking pin groove that extends through the edge of the connecting pipe 160. In general, the drill pipe drill collar 150 may include one or more grooves for the locking pin. In this embodiment, the drill pipe tool joint 150 includes two grooves for the locking pin, which are designated as grooves 169a and 169b for the locking pin. In this embodiment, the locking pin grooves 169a and 169b are located opposite each other, with the locking pin grooves 169a and 169b located near the edges 161 and 162 of the connecting pipe, respectively. In particular, the locking pin grooves 169a and 169b extend through the edges 161 and 162 of the connecting pipe, respectively. The locking pin groove 169a and 169b passes through the connecting pipe faces 161 and 162, respectively, so that the locking pin grooves 169a and 169b face the internal holes of the locking pins 135a and 135b, respectively, when the faceted socket 140 receives the faceted connecting pipe, as discussed in more detail below.

[104] It should be noted that the locking pin groove 169a can extend through the connecting pipe portion 163 and 168, as shown in FIG. 5a and 5b, respectively. Additionally, the locking pin groove 169b may extend through the connecting pipe portion 167 and 164, as shown in FIG. 5a and 5b, respectively. Thus, the drill collar 150 may include grooves for a locking pin that extend through a faceted connecting pipe.

[105] In FIG. 6a is a longitudinal sectional view of an embodiment of a drill string 100a that includes a tool assembly 108a, wherein the tool assembly 108a includes a drill lock adapter 130 and a drill pipe tool joint 150 connected together, and FIG. 6b and 6c show fragments of the drill string 100a of FIG. 6a. It should be noted that, in this embodiment, the drill pipe 110 is connected to the locking sleeve 150. In particular, the threaded locking nipple 119 (FIG. 2a) is connected to the threaded locking sleeve 153 (FIG. 5b). A threaded locking nipple 119 is connected to a threaded locking sleeve 153, and the threaded pin 114 is screwed onto the coupling thread 154 (FIG. 5b).

[106] Additionally, drill pipe 120 may be coupled to a drill lock adapter 130. In this embodiment, the threaded lock sleeve 123 (FIG. 3a) is removed from the pipe body 121 and replaced with a drill lock adapter 130. In particular, the threaded lock sleeve 123 is removed from the pipe body 121, and the drill pipe adapter connecting pipe 134 is connected to the pipe body 121. The drill pipe adapter connector 134 can be attached to the pipe body 121, for example by welding, with a seal being formed between them.

[107] It should be noted that the internal channels of the drill pipe 112 and 122 can be hydraulically connected to each other through the drill pipe lock sleeve 150 and the drill lock adapter 130. In particular, the inner channels 112 and 122 of the drill pipe can be hydraulically connected to each other through the inner channel 132 of the adapter of the drill joint and the inner channel 152 of the tool joint. Thus, the material can pass between the inner channels 112 and 122 of the drill pipe through the inner channel 132 of the adapter of the drill joint and the inner channel 152 of the castle coupling. As discussed in more detail above, the inner channel 132 of the drill joint adapter may pass through the adapter 130 of the drill joint, and the inner channel 152 of the drill joint passes through the lock coupling 150 of the drill pipe.

[108] In this embodiment, the sealing elements 272 and 273 are connected to the sealing nipple 155. In particular, the sealing elements 272 and 273 carry the sealing nipple 155, while they pass through the sealing grooves 156a and 156b, respectively, as shown in FIG. 6c. Sealing elements 272 and 273 may be, for example, annular gaskets of circular cross-section of various types. It should be noted that, in some embodiments, the implementation of the drill joint adapter body 131 includes grooves opposite the sealing grooves 156a and 156b. However, in other embodiments, for example, the embodiment indicated by arrow 117 in FIG. 6a, the drill lock adapter housing 131 does not include grooves opposite to the sealing grooves 156a and 156b.

[109] In this embodiment, a faceted nipple 158 (FIG. 5a) extends through a drill lock adapter housing 131. In particular, the faceted connecting pipe 160 and the sealing nipple 155 pass through the inner channel 132 of the drill adapter and the annular surface 149 of the socket (Fig. 4c, 4d and 6b). The seal nipple 155 extends through the drill lock adapter housing 131, so that a seal is formed by the sealing elements 272 and 273 cooperating to create a seal with the inner periphery of the drill lock adapter housing 131.

[110] The faceted connecting pipe 160 (Figs. 5a and 5b) can pass through the drill lock adapter housing 131, so that the faceted connecting pipe 160 faces the socket surface 140 (Figs. 4c and 4d). In particular, a faceted connecting pipe may extend through the housing of the drilllock adapter 130, so that faces 161, 162, 163, 164, 165, 166, 167 and 168 of the connecting pipe face the faces 141, 142, 143, 144, 145, 146, 147 and 148 nests respectively. In this embodiment, the faces 161, 162, 163, 164, 165, 166, 167 and 168 of the connecting pipe interact with the faces 141, 142, 143, 144, 145, 146, 147 and 148 of the socket, respectively, so that the rotation of the lock coupling 150 the drill pipe relative to the adapter 130 of the drill lock is restrained.

[111] In addition, a faceted connecting pipe may extend through the drill lock adapter housing 131 so that the locking pin grooves 169a and 169b (FIGS. 5a and 5b) are facing the locking pin pin holes 135a and 135b (FIG. 4d), respectively . The locking pin grooves 169a and 169b can be inserted in front of the internal locking pin pins 135a and 135b, respectively, when the edges 161, 162, 163, 164, 165, 166, 167 and 168 of the connecting pipe face the edges 141, 142, 143, 144, 145, 146, 147 and 148 nests, respectively.

[112] In this embodiment, the locking pin 270a may extend through the inner hole 135a for the locking pin and the groove 169a for the locking pin. In some embodiments, the locking pin 270a may extend through the inner hole 135a for the locking pin and the groove 169a for the locking pin when the locking pin passes through the opening 137a of the opening for the locking pin. In some embodiments, the locking pin 270a passes through the inner hole 135a for the locking pin and the groove 169a for the locking pin when passing through the hole 138a for the locking pin.

[113] The movement between the drill joint adapter 130 and the drill pipe tool joint 150 may be restrained by the passage of the locking pin 270a through the inner hole 135a for the locking pin and the groove 169a for the locking pin. In particular, the movement of the drill joint adapter 130 and the drill pipe keyhole 150 from each other may be restrained by the passage of the locking pin 270a through the inner hole 135a for the locking pin and the groove 169a for the locking pin. The locking pin 270a may block the drill joint adapter 130 with the drill collar 150 when the lock pin restrains the drill adapter 130 and the drill collar 150 from each other.

[114] In this embodiment, the fastener 271a passes through the fastener opening 136a (Figs. 4c, 4d, 6b, and 6c). A fastener 271a extends through an aperture 136a of the fastener and interacts with a locking pin 270a. The fastener 271a cooperates with the locking pin 270a, restraining its movement through the inner hole 135a under the locking pin. Thus, an unacceptable movement of the locking pin 270a through the openings 137a and 138a of the hole for the locking pin and its exit from the inner hole 135a for the locking pin and the groove 169a for the locking pin becomes less likely. The movement between the drill joint adapter 130 and the drill pipe tool joint 150 may be less likely to be restrained when the locking pin 270a leaves the inner hole 135a for the locking pin and the groove 169a for the locking pin. Thus, it may be necessary to secure the locking pin 270a in the inner hole 135a for the locking pin and the groove 169a for the locking pin. The fastener 271a may be, for example, various types of clamping screws. As shown in FIG. 6b, the fastener 271a is recessed into the drill lock adapter housing 131, so that the fastener cannot be cut.

[115] In this embodiment, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 169b for the locking pin. In some situations, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 169b for the locking pin when passing through the opening of the hole for the locking pin 137b. In some embodiments, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 169b for the locking pin when passing through the opening 138b of the hole for the locking pin.

[116] The movement between the drilllock adapter 130 and the drill pipe tool joint 150 may be restrained by the passage of the locking pin 270b through the inner hole 135b for the locking pin and the groove 169b for the locking pin. In particular, the movement of the drill joint adapter 130 and the drill pipe keyhole 150 from each other may be restrained by the passage of the locking pin 270b through the internal hole 135b for the locking pin and the groove 169b for the locking pin. The locking pin 270b may block the drill joint adapter 130 with the drill pipe lock sleeve 150 when the lock pin restrains the movement of the drill lock adapter 130 and the drill pipe lock sleeve 150 from each other.

[117] In this embodiment, the fastener 271b extends through the fastener opening 136b (Figs. 4d and 6c). The fastener 271b extends through the opening 136b of the fastener and interacts with the locking pin 270b. The fastener 271b cooperates with the locking pin 270b, restraining its movement through the inner hole 135b under the locking pin. Thus, an unacceptable movement of the blocking pin 270b through the openings for the blocking pin and its exit from the inner hole 135b for the blocking pin and the groove 169b for the blocking pin becomes less likely. The movement between the drill-lock adapter 130 and the drill pipe-lock coupling 150 may be less likely to be restrained by the release of the locking pin 270b from the inner hole 135b of the locking pin and the groove 169b of the locking pin. Thus, it may be necessary to secure the locking pin 270b in the inner hole 135b for the locking pin and the groove 169b for the locking pin. The fastener 271b may be, for example, various types of clamping screws. The fastener 271b can be sunk into the housing 13 of the adapter of the drill lock so that the fastener cannot be cut.

[118] In FIG. 7 is a perspective view of an embodiment of a drill pipe tool nipple 170. In this embodiment, the drill pipe tool nipple 170 includes a tool nipple housing 171 with an internal tool nipple passage 172 passing therethrough. The drill pipe locking nipple 170 includes a locking nipple 179 with a thread at one end and a faceted nipple 198 at the opposite end. It should be noted that the inner channel 172 of the locking nipple passes through the threaded locking nipple 179 and the faceted nipple 198, and allows the passage of material through it.

[119] A threaded locking nipple 179 may include a nipple cylinder 175, which may extend from the shoulder of the nipple 176, and a threaded nipple 173, which may include a nipple thread 174. The nipple cylinder 175 may be located close to the nipple shoulder 176, and the threaded nipple 173 is located at a distance from the nipple shoulder 176. The threaded nipple 173 is assigned from the shoulder of the nipple 176 by the connecting pipe 175 of the nipple. A nipple cylinder 175 is located between the threaded nipple 173 and the nipple shoulder 176. The cylinder 175 of the nipple is not a faceted connecting pipe, and this includes a curved surface of continuous curvature, and does not include a flat face with interrupted curvature. A nipple cylinder 175 extends through a threaded drill collar, such as a drill pipe 120, when the nipple cylinder is connected to the drill pipe 110. It should be noted that the inner channel 172 of the drill pipe nipple can pass through a nipple cylinder 175 and a threaded nipple 173. .

[120] In this embodiment, the faceted nipple 198 includes a faceted connecting pipe 180 that extends outward from the shoulder 177 of the nipple. The faceted nipple 198 includes a sealing nipple 195, the faceted connecting pipe 180 being installed near the shoulder 177 of the nipple, and the sealing nipple 195 installed at a distance from the shoulder 177 of the nipple. The sealing nipple 195 is separated from the shoulder 177 of the nipple by the faceted connecting pipe 180. The faceted connecting pipe 180 is located between the shoulder 177 of the nipple and the sealing nipple 195. It should be noted that the shoulder 177 of the nipple is facing the faceted connecting pipe 180 and the sealing nipple 195, and facing away from the locking nipple 195 179 threaded. It should also be noted that the inner channel 172 of the drill pipe nipple passes through the faceted connecting pipe 180 and the sealing nipple 195, and allows the passage of material through it.

[121] The nipple 195 may be a sealing nipple, since it may form a seal with another component, as discussed in more detail below. In this embodiment, the sealing nipple 195 includes a sealing groove extending in a ring around it. The sealing groove receives a sealing element, for example, an O-ring, wherein the sealing element forms a seal with another component. Thus, the nipple 195 is a sealing nipple. In this embodiment, the sealing nipple 195 includes two sealing grooves, designated as sealing grooves 196a and 196b. In general, the drill pipe seal nipple 195 includes one or more sealing grooves.

[122] The connecting pipe 180 may be a faceted connecting pipe, because it may include two faces with intermittent curvature between them, and may not include a curved surface with continuous curvature, as discussed in more detail here. The faceted connecting pipe 180 may include a connecting face. In this embodiment, the faceted connecting pipe 180 includes opposing edges 181 and 182 of the connecting pipe, opposite edges 183 and 184 of the connecting pipe, opposite edges 185 and 186 of the connecting pipe, and opposite edges 187 and 188 of the connecting pipe. It should be noted that the faceted connecting pipe 180 includes eight faces of the connecting pipe as an illustration in this embodiment. However, typically a faceted connecting pipe 180 includes one or more faces of the connecting pipe. The number of faces of the faceted connecting pipe 180 corresponds to the number of faces of the faceted socket 140, so that the faceted socket 140 can receive a faceted connecting pipe 180.

[123] It should also be noted that the faces 181 and 183 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 183 and 185 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 185 and 187 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 187 and 182 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 182 and 184 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 184 and 186 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. The faces 186 and 188 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 180 is interrupted between them. Thus, the connecting pipe 180 is a faceted connecting pipe.

[124] In this embodiment, the drill pipe tool nipple 170 includes a locking pin groove that extends through a facet of the faceted connecting pipe 180. In general, the drill pipe tool nipple 170 includes one or more grooves for the locking pin. In this embodiment, the drill pipe locking nipple 170 includes two grooves for the locking pin, which are designated as grooves 189a and 189b for the locking pin. Also in this embodiment, the locking pin grooves 189a and 189b are located opposite to each other, with the locking pin grooves 189a and 189b located near the edges 181 and 182 of the connecting pipe, respectively. In particular, the locking pin grooves 189a and 189b extend through the edges 181 and 182 of the connecting pipe, respectively. The locking pin grooves 189a and 189b pass through the connecting pipe edges 181 and 182, respectively, so that the locking pin grooves 189a and 189b are facing the internal holes of the locking pins 135a and 135b (Fig. 4d), respectively, when the faceted socket 140 receives the faceted connecting pipe 180, as discussed in more detail below.

[125] It should be noted that the groove 189a for the locking pin may extend through a portion of the faces 183 and 188 of the connecting pipe. Additionally, the locking pin groove 189b may extend through a portion of the faces 187 and 184 of the connecting pipe. Thus, the drill pipe tool nipple 170 may include locking pin grooves that extend through the faceted connecting pipe.

[126] In FIG. 8a shows a longitudinal section through an embodiment of a drill string 100b that includes a tool assembly 108b, wherein the tool assembly 108b includes coupled a drill lock adapter 130 to a drill pipe tool nipple 170, and FIG. 8b and 8b show fragments of the drill string 100b of FIG. 8a. It should be noted that, in this embodiment, the drill pipe 120 is connected to the drill pipe tool nipple 170. In particular, the threaded locking nipple 179 (FIG. 7) is connected to the threaded locking sleeve 123 (FIG. 3a). A threaded locking nipple 179 is connected to a threaded locking sleeve 123 so that the threaded nipple thread 174 is screwed onto the coupling thread 124 (Fig. 3a).

[127] Additionally, drill pipe 110 may be coupled to a drill lock adapter 130. In this embodiment, a threaded locking nipple 119 (FIG. 2a) is removed from the pipe body 111 and replaced with a drill lock adapter 130. In particular, the threaded locking nipple 119 is removed from the pipe body 111, and the drill pipe adapter connection pipe 134 is connected to the pipe body 111. The drill pipe adapter connecting pipe 134 is fastened to the pipe body 111, for example by welding, with a seal being formed between them.

[128] It should be noted that the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the drill pipe nipple 170 and the drill lock adapter 130. In particular, the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the inner channel 132 of the drill adapter and the inner channel 172 of the drill pipe nipple. In this way, material can pass between the inner channels 112 and 122 of the drill pipe through the inner channel 132 of the drill adapter and the inner channel 172 of the drill pipe nipple. As discussed in more detail above, the inner channel 132 of the drill adapter passes through the adapter 130 of the drill, and the internal channel 172 of the drill pipe nipple passes through the drill pipe nipple 170.

[129] In this embodiment, the sealing elements 272 and 273 are connected to the sealing nipple 195. In particular, the sealing elements 272 and 273 carry the sealing nipple 195, while they pass through the sealing grooves 196b and 196a, respectively, as shown in FIG. 8c. Sealing elements 272 and 273 may be, for example, annular gaskets of circular cross-section of various types.

[130] In this embodiment, a faceted nipple 198 (FIG. 7) extends through a drill lock adapter housing 131. In particular, the faceted connecting pipe 180 and the sealing nipple 195 pass through the inner channel 132 of the drill adapter and the annular surface 149 of the socket (Fig. 4c, 4d and 8b). The seal nipple 195 extends through the drill joint adapter housing 131 so that a seal is formed by the sealing members 272 and 273 cooperating with the seal to the inner periphery of the drill lock adapter housing 131.

[131] The faceted connecting pipe 180 in the embodiment shown in FIG. 7 passes through the drill lock adapter housing 131 so that the faceted connecting pipe 180 faces the socket end 140 (Figs. 4c and 4d). In particular, the faceted connecting pipe 180 extends through the housing of the drilllock adapter 130 so that the faces 181, 182, 183, 184, 185, 186, 187 and 188 of the connecting pipe face the faces 141, 142, 143, 144, 145, 146, 147 and 148 nests, respectively. In this embodiment, the edges 181, 182, 183, 184, 185, 186, 187 and 188 of the connecting pipe interact with the edges 141, 142, 143, 144, 145, 146, 147 and 148 of the socket, respectively, so that the rotation of the locking nipple 170 the drill pipe relative to the adapter 130 of the drill lock is held back.

[132] In addition, in this embodiment, the faceted connecting pipe 180 extends through the drill lock adapter housing 131 so that the locking pin grooves 189a and 189b (FIG. 7) face the inner holes of the locking pins 135a and 135b (FIG. 4d) , respectively. The locking pin grooves 189a and 189b are inserted in front of the inner holes of the locking pins 135a and 135b, respectively, in response to installing faces 181, 182, 183, 184, 185, 186, 187 and 188 of the connecting pipe against faces 141, 142, 143, 144 , 145, 146, 147, and 148 nests, respectively.

[133] In this embodiment, the locking pin 270a passes through the inner hole 135a for the locking pin and the groove 189a for the locking pin. In some situations, the locking pin 270a passes through the inner hole 135a for the locking pin and the groove 189a for the locking pin when it passes through the opening 137a of the hole for the locking pin. In some situations, the locking pin 270a passes through the inner hole 135a for the locking pin and the groove 189a for the locking pin when it passes through the opening 138a of the hole for the locking pin.

[134] The movement between the drill lock adapter 130 and the drill pipe tool nipple 170 may be restrained by a blocking pin 270a passing through the inner hole 135a of the blocking pin and a groove 189a of the blocking pin. In particular, the movement of the drill lock adapter 130 and the drill pipe tool nipple 170 from each other may be restrained by a blocking pin 270a passing through the inner hole 135a for the blocking pin and a groove 189a for the blocking pin. The locking pin 270a may block the drilllock adapter 130 with the drill pipe nipple 170 when the lock pin restrains the drill adapter 130 and the drill pipe drill nipple 170 from each other.

[135] In this embodiment, the fastener 271a extends through the fastener opening 136a (Figs. 4c, 4d, 8b and 8c). A fastener 271a extends through an aperture 136a of the fastener and interacts with a locking pin 270a. The fastener 271a cooperates with the locking pin 270a, restraining its movement through the inner hole 135a under the locking pin. Thus, an unacceptable movement of the blocking pin 270a through the opening for the blocking pin and its exit from the inner hole 135a for the blocking pin and the groove 189a for the blocking pin becomes less likely. The movement between the drill joint adapter 130 and the drill pipe tool nipple 170 may be less likely to be restrained when the locking pin 270a leaves the inner hole 135a for the locking pin and the groove 189a for the locking pin. Thus, the locking pin 270a needs to be secured in the inner hole 135a for the locking pin and the groove 189a for the locking pin. The fastener 271a may be, for example, various types of clamping screws. As shown in FIG. 8b, the fastener 271a is recessed into the drill lock adapter housing 131 so that it cannot be cut off.

[136] In this embodiment, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 189b for the locking pin. In some situations, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 189b for the locking pin when the locking pin passes through the opening of the hole for the locking pin 137b. In some situations, the locking pin 270b passes through the inner hole 135b for the locking pin and the groove 189b for the locking pin when it passes through the opening 138b of the hole for the locking pin.

[137] The movement between the drill lock adapter 130 and the drill pipe tool nipple 170 may be restrained by the passage of the locking pin 270b through the internal hole 135b for the locking pin and the groove 189b for the locking pin. In particular, the movement of the drill joint adapter 130 and the drill pipe tool nipple 170 from each other may be restrained by the passage of the locking pin 270b through the inner hole 135b for the locking pin and the groove 189b for the locking pin. The locking pin 270b may block the drilllock adapter 130 with the drill pipe tool nipple 170 when it restrains the movement of the drill tool adapter 130 and the drill pipe tool nipple 170 from each other.

[138] In this embodiment, the fastener 271b extends through the fastener opening 136b (Figs. 4d and 8c). The fastener 271b extends through the opening 136b of the fastener and interacts with the locking pin 270b. The fastener 271b cooperates with the locking pin 270b, restraining the movement of the locking pin through the inner hole 135b under the locking pin and the groove 189b under the locking pin. In this way, the unacceptable movement of the locking pin 270b through the openings for the locking pin, its exit from the inner hole 135b for the locking pin and the groove 189b for the locking pin, becomes unacceptable. The movement between the drill joint adapter 130 and the drill pipe tool nipple 170 may be less likely to be restrained when the locking pin 270b leaves the inner hole 135b for the locking pin and the groove 189b for the locking pin. Thus, the locking pin 270b needs to be secured in the inner hole 135b for the locking pin and the groove 169b for the locking pin. The fastener 271b may be, for example, various types of clamping screws. The fastener 271b can be flush with the housing 131 of the adapter of the drill joint so that it is not possible to cut it.

[139] In FIG. 9a and 9c are isometric views of a drill collar 200, and FIG. 9b and 9d show end faces of the drill collar 200 from opposite directions, positions 209a and 209b, respectively. In this embodiment, the drill pipe tool sleeve 200 includes a tool sleeve body 201 with an internal tool sleeve passage 202 passing therethrough. The inner channel 202 of the adapter of the drilllock allows the passage of material through the housing 201 of the drill pipe coupling. The drill pipe tool joint 200 includes a thread lock 203 at one end and a faceted socket 210 at the opposite end. It should be noted that the inner channel 202 of the drill pipe tool sleeve extends through the threaded tool sleeve 203 and the faceted socket 210, and allows material to pass through it. A threaded key sleeve 203 includes a sleeve thread 204 that faces the inner channel 202 of the drill pipe key sleeve.

[140] As best shown in FIG. 9c and 9d, the drill collar 200 may include a faceted socket 210 that includes a surface of the socket. In this embodiment, the faceted nest 210 includes opposing nesting faces 211 and 212, opposing nesting faces 213 and 214, opposing nesting faces 215 and 216, and opposing nesting faces 217 and 218. Facets 211, 212, 213, 214, 215, 216, 217 and 218 of the socket extend through the annular end face 219 of the socket, and face the inner channel 202 of the drill collar. It should also be noted that, according to this embodiment, the faceted socket 210 includes eight facets of the socket as an illustration in this embodiment. However, typically a faceted nest 210 includes one or more faces of the nest. It should be noted that socket 210 is a faceted socket because it includes two faces with intermittent curvature between them, as discussed in more detail here, and does not include a curved surface with continuous curvature. The faceted socket 210 faces the inner channel 202 of the drill collar, and the internal channel 202 of the drill collar passes through the faceted socket 210 and the end face 219 of the socket, and allows material to pass through it.

[141] The faces 211 and 213 of the nest can be angled relative to each other, so that the curvature of the faceted nest 210 is interrupted between them. The faces 213 and 215 of the nest can be angled relative to each other, so that the curvature of the faceted nest 210 is interrupted between them. Socket faces 215 and 217 may be angled relative to each other so that the curvature of the faceted socket 210 is interrupted between them. The faces 217 and 212 of the nest can be angled relative to each other, so that the curvature of the faceted nest 210 is interrupted between them. The faces 212 and 214 of the nest can be angled relative to each other, so that the curvature of the faceted nest 210 is interrupted between them. Socket faces 214 and 216 may be angled relative to each other so that the curvature of the faceted socket 210 is interrupted between them. Socket faces 216 and 218 may be angled relative to each other so that the curvature of the faceted socket 210 may interrupt between them. Thus, nest 210 may be a faceted nest.

[142] In this embodiment, the drill collar 200 includes an inner hole for locking pins that extends through the drill collar housing 201. In general, a drill pipe tool joint 200 includes one or more internal holes for locking pins. In this embodiment, the drill collar 200 includes two internal holes for the locking pins, which are designated as internal holes 225a and 225b for the locking pins, as shown in FIG. 9d. In this embodiment, the internal holes for the locking pins 225a and 225b are located opposite to each other, while the internal holes 225a and 225b for the locking pins are located near the edge 211 and 212 of the socket, respectively. In particular, the internal holes for the locking pins 225a and 225b pass through the edges 211 and 212 of the socket, respectively. The inner holes 225a and 225b for the locking pins open into the inner channel 202 of the drill pipe coupling.

[143] In this embodiment, the inner pin pin hole 225a includes opposing pin pin holes 227a and 228a, and the fastener opening 226a that passes through the drill pipe drill collar body 201 and the pin pin lock hole 225a. In particular, the fastener opening 226a extends between the outer periphery of the drill pipe drill collar housing 201 and the faceted socket 211. It should be noted that the portion of the inner pin pin 225a near the fastener opening 226a faces the inner channel 202 of the drill pipe drill coupler. A portion of the locking pin inner hole 225a facing the opening 226a of the fastener opens into the inner channel 202 of the drill collar.

[144] In this embodiment, the locking pin inner hole 225b includes opposing locking pin holes 227b and 228b and the fastener opening 226b that passes through the drill pipe tool body 201 and the locking pin locking hole 225b In particular an aperture 226b of the fastener extends between the outer periphery of the drill pipe tool body 201 and the socket face 212. It should be noted that the portion of the inner hole 225b for the locking pin near the opening 226b of the fastener faces into the inner channel 202 of the drill collar. A portion of the inner pin 225b for the locking pin facing the opening 226b of the fastener opens into the inner channel 202 of the drill collar.

[145] In FIG. 10a and 10b are a perspective view of a drill lock adapter 230. In this embodiment, the drill lock adapter 230 includes a drill lock adapter housing 231 with a drill hole adapter inner passage 232 passing therethrough. The drill lock adapter 230 includes a faceted nipple 239 at one end and a drill lock adapter connection pipe 234 at the opposite end. It should be noted that the inner channel 232 of the adapter of the drill joint passes through the faceted nipple 239 and the connecting pipe 234 of the adapter of the drill joint, and allows the passage of material through it.

[146] The adapter pipe 234 of the drill joint adapter may extend from a shoulder 238 of the connector. The drill pipe adapter connecting pipe 234 may be sized and shaped to receive pipes, such as pipe bodies 111 and 121, into the body. The drill pipe adapter connection pipe 234 may not be a faceted connection pipe because it may include a curved surface with continuous curvature, and may not include a flat face with interrupted curvature. It should be noted that the inner channel 232 of the adapter of the drill joint can pass through the connecting pipe 234 of the adapter of the drill joint and allows the passage of material through it.

[147] A drill pipe adapter connecting pipe 234 may be received into the pipe body after removing a threaded sleeve or threaded locking nipple from it. In some embodiments, the implementation of the drill pipe adapter 234 is welded to the pipe body. It should be noted that the drill lock adapter 230 can usually be repeatedly removed from the pipe body. Thus, a threaded locking nipple 119 (FIG. 2a) can be removed from the pipe body and replaced with a drill lock adapter 230. Additionally, the threaded lock sleeve 123 (FIG. 3a) can be removed from the pipe body and replaced with a drill lock adapter 230. However, as mentioned above, it is usually difficult to remove these components from the pipe body at remote sites, since specialized tools are required.

[148] In this embodiment, the faceted nipple 239 includes a faceted connecting pipe 240 that extends outward from the shoulder 237 of the nipple. The faceted nipple 239 includes a sealing nipple 235, the faceted connecting pipe 240 being installed near the shoulder 237 of the nipple, and the sealing nipple 235 installed at a distance from the shoulder 237 of the nipple. The sealing nipple 235 is assigned from the ledge 237 of the nipple to the faceted connecting pipe 240. The faceted connecting pipe 240 is located between the ledge 237 of the nipple and the sealing nipple 235. It should be noted that the ledge 237 of the nipple faces the faceted connecting pipe 240 and the sealing nipple 235, and is turned away from 234 drill lock adapters. It should also be noted that the inner channel 232 of the drill joint adapter may extend through a faceted connecting pipe 240 and a sealing nipple 235. Additionally, the shoulder 237 of the nipple is opposite the shoulder 238 of the connecting pipe.

[149] The nipple 235 may be a sealing nipple, since it may form a seal with another component, as discussed in more detail below. In this embodiment, the sealing nipple 235 may include a sealing groove extending a ring around it. The sealing groove may receive a sealing element, such as an O-ring, wherein the sealing element forms a seal with another component. Thus, the nipple 235 may be a sealing nipple. In this embodiment, the sealing nipple 235 may include two sealing grooves, designated as sealing grooves 236a and 236b. In general, a drill lock adapter seal nipple 235 may include one or more seal grooves.

[150] The connecting pipe 240 may be a faceted connecting pipe, because it may include two surfaces with intermittent curvature between them, and may not include a curved surface with continuous curvature, as discussed in more detail here. The faceted connecting pipe 240 may include a connecting surface. In this embodiment, the faceted connecting pipe 240 includes opposing pipe faces 241 and 242, opposing pipe faces 243 and 244, opposite pipe faces 245 and 246, and opposite pipe faces 247 and 248. It should be noted that the faceted connecting pipe 240 includes eight faces as an illustration in this embodiment. However, typically a faceted connecting pipe 240 includes one or more faces. The number of faces of the faceted connecting pipe 240 corresponds to the number of faces of the faceted socket 210, so that the faceted socket 210 can receive a faceted connecting pipe 240.

[151] It should also be noted that the faces 241 and 243 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 243 and 245 of the connecting pipe may be angled relative to each other so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 245 and 247 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 247 and 242 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 242 and 244 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 244 and 246 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. The faces 246 and 248 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 240 is interrupted between them. Thus, the connecting pipe 234 may be a faceted connecting pipe.

[152] In this embodiment, the drill lock adapter 230 includes a lock pin groove that extends through the face of the faceted connecting pipe 240. In general, the drill lock adapter 230 includes one or more lock lock pin slots. In this embodiment, the drill lock adapter 230 includes two grooves for the locking pin, which are designated as grooves 249a and 249b for the locking pins. In this embodiment, the locking grooves grooves 249a and 249b are located opposite to each other, while the locking grooves grooves 249a and 249b are located near the faces 241 and 242 of the connecting pipe, respectively. In particular, the grooves 249a and 249b for the locking pins can pass through the edges 241 and 242 of the connecting pipe, respectively. The locking grooves grooves 249a and 249b pass through the faces 241 and 242 of the connecting pipe, respectively, so that the locking grooves grooves 249a and 249b of the locking pins face the internal locking pin holes 225a and 225b, respectively, when the faceted socket 210 receives the faceted connecting pipe 240, as discussed in more detail below.

[153] It should be noted that the groove 249a for the locking pin may extend through a portion of the faces 243 and 248 of the connecting pipe. Additionally, the locking pin groove 249b may extend through a portion of faces 247 and 244 of the connecting pipe. Thus, the drill lock adapter 230 may include a slot for a locking pin that extends through a faceted connection pipe.

[154] In FIG. 11a is an isometric view of an embodiment of a drill collar nipple 250, and FIG. 11b shows an end view of the drill pipe tool nipple 250 in the direction 279. In this embodiment, the drill pipe tool nipple 250 includes a tool nipple housing 251 with an internal tool nipple passage 252 passing therethrough. The drill pipe tool nipple 250 includes a thread lock nipple 259 at one end and a faceted socket 260 at the opposite end. It should be noted that the inner channel 252 of the drill pipe tool nipple passes through the threaded tool nipple 259 and the faceted socket 260 and allows material to pass through it.

[155] A threaded locking nipple 259 may include a nipple cylinder 255 that extends from the shoulder of the 256 nipple and a threaded locking nipple 253 that includes a threaded nipple 254. The cylinder 255 of the nipple can be located near the ledge 256 of the nipple, and the locking nipple 253 with a thread can be located at a distance from the ledge of the 256 nipple. A threaded locking nipple 253 may be assigned from the shoulder of the 256 nipple to the cylinder 255 of the nipple. The cylinder 255 of the nipple can be located between the locking nipple 253 with a thread and the ledge 256 of the nipple. The cylinder 255 of the nipple may not be a faceted connecting pipe, since it includes a curved surface with continuous curvature and does not include a flat face with intermittent curvature. The nipple cylinder 255 may pass through a threaded lock sleeve of another drill pipe, such as drill pipe 120, when the latter is connected to the drill pipe 110. It should be noted that the inner channel 252 of the drill pipe nipple can pass through the nipple cylinder 255 and the lock nipple 253 sec thread, and can allow the passage of material through it.

[156] As best shown in FIG. 11b, a faceted socket 260 may include a surface of the socket. In this embodiment, the faceted nest 260 includes opposing nests 261 and 262, opposite nests 263 and 264, opposite nests 265 and 266, and opposite nests 267 and 268. Facets 261, 262, 263, 264, 265, 266, 267 and 268 of the socket can pass through the annular face 269 of the socket, and face the inner channel 252 of the drill pipe nipple. The annular edge 269 of the socket is opposite to the ledge 253 of the connecting pipe. Thus, the faceted socket 260 faces the inner channel 252 of the drill pipe nipple, and the internal channel 252 of the drill pipe nipple passes through the faceted socket 260 and face 269 of the socket. The inner channel 252 of the drill pipe nipple can pass through a faceted socket 260 and allows material to pass through it.

[157] It should also be noted that faceted socket 260 includes eight facets of the socket as an illustration in this embodiment. However, in general, a faceted nest 260 may include one or more faces of the nest. It should be noted that nest 260 is a faceted nest because it includes two faces with intermittent curvature between them, as discussed in more detail here, and does not include a curved surface with continuous curvature.

[158] The faces 261 and 263 of the nest can be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. The faces 263 and 265 of the nest can be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. The faces 265 and 267 of the nest can be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. The faces 267 and 262 of the nest may be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. Socket faces 262 and 264 may be angled relative to each other so that the curvature of the faceted socket 260 is interrupted between them. The faces 264 and 266 of the nest can be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. The faces 266 and 268 of the nest can be angled relative to each other, so that the curvature of the faceted nest 260 is interrupted between them. Thus, faceted nest 260 is a faceted nest.

[159] In this embodiment, the drill pipe tool nipple 250 includes an internal hole for the locking pins that extends through the drill pipe tool nipple body 251. In general, drill pipe tool nipple 250 includes one or more internal holes for locking pins. In this embodiment, the drill collar nipple 250 includes two internal holes for the locking pins, which are designated as internal holes 275a and 275b for the locking pins, as shown in FIG. 4d. In this embodiment, the internal holes for the locking pins 275a and 275b are located opposite to each other, while the internal holes 275a and 275b for the locking pins are located near the edge 261 and 262 of the socket, respectively. In particular, the inner holes 275a and 275b for the locking pins can pass through the edges 261 and 262 of the socket, respectively. The inner holes 275a and 275b for the locking pins can open into the inner channel 252 of the drill pipe nipple.

[160] In this embodiment, the inner pin pin hole 275a includes opposing pin pin holes 277a and 278a and the fastener opening 276a that passes through the drill pipe tool body 251 and the pin pin lock hole 275a. In particular, the fastener opening 276a may extend between the outer periphery of the drill pipe nipple housing 251 and the socket face 261. It should be noted that the portion of the inner hole 275a for the locking pin near the opening 276a of the fastener faces the inner channel 252 of the drill pipe nipple. A portion of the locking pin inner hole 275a facing the fastener opening 276a may open into the inner channel 252 of the drill pipe nipple.

[161] In this embodiment, the inner pin pin hole 275b includes opposing pin pin holes 277b and 278b and the fastener opening 276b that passes through the drill pipe tool body 251 and the pin pin inner hole 275b. In particular, according to this embodiment, the fastener opening 276b extends between the outer periphery of the drill pipe nipple housing 251 and the socket face 262. It should be noted that the portion of the inner hole 275b for the locking pin near the opening 276b of the fastener may be facing the inner channel 252 of the drill pipe nipple. A portion of the locking pin inner hole 275b facing the fastener opening 276b may open into the inner channel 252 of the drill pipe nipple.

[162] In FIG. 12a and 12b are an isometric view of an embodiment of a drill lock adapter 280. In this embodiment, the drilllock adapter 280 includes an adapter body 281 with an adapter channel 282 passing therethrough. The drill lock adapter 280 includes a faceted nipple 289 at one end and a drill lock adapter connection pipe 284 at the opposite end. It should be noted that the channel 28 of the adapter of the drill joint can pass through the faceted nipple 289 and the connecting pipe 284 of the adapter of the drill joint and allows the passage of material through it.

[163] The drill pipe adapter connecting pipe 284 may extend from the shoulder 288 of the connecting pipe. The drill pipe adapter connector 284 may be sized and shaped to receive the drill rod body, such as rod bodies 111 and 121, into the body. The drill pipe adapter connection pipe 284 is not a faceted connection pipe because it includes a curved surface with continuous curvature and does not include a flat face with intermittent curvature. It should be noted that the channel 28 of the adapter of the drill lock can pass through the connecting pipe 284 of the adapter of the drill lock, and can allow the passage of material through it.

[164] The drill pipe adapter connecting pipe 284 may be received into the drill stem body after removing a threaded lock sleeve or a threaded lock nipple from it. In some embodiments, the implementation of the adapter pipe 284 of the adapter of the drill joint is welded to the body of the drill stem. It should be noted that the adapter 280 of the drill lock can be configured to repeatedly remove from the body of the drill rod. Thus, the threaded locking nipple 119 (FIG. 2a) can be removed from the drill rod body and replaced by the drill lock adapter 280. Additionally, a threaded lock sleeve 123 (FIG. 3a) can be removed from the drill stem body and replaced with a drill lock adapter 280.

[165] In this embodiment, the faceted nipple 289 includes a faceted connecting pipe 290 that extends outward from the shoulder 287 of the nipple. Faceted nipple 289 includes a sealing nipple 285, with a faceted connecting pipe 290 installed near the shoulder 287 of the nipple, and the sealing nipple 285 installed at a distance from the shoulder 287 of the nipple. The sealing nipple 285 is assigned from the shoulder 287 of the nipple to the faceted connecting pipe 290. The faceted connecting pipe 290 is located between the shoulder 287 of the nipple and the sealing nipple 285. It should be noted that the ledge 287 of the nipple faces the faceted connecting pipe 290 and the sealing nipple 284 and 285 and drill lock adapter. It should also be noted that the channel of the adapter of the drill lock passes through the faceted connecting pipe 290 and the sealing nipple 285. Additionally, the shoulder 287 of the nipple is opposite to the shoulder 288 of the connecting pipe.

[166] Nipple 285 is a sealing nipple because it forms a seal with another component, as discussed in more detail below. In this embodiment, the sealing nipple 285 includes a sealing groove extending by a ring around it. The sealing groove receives a sealing element, such as an O-ring, wherein the sealing element forms a seal with another component. Thus, the nipple 285 is a sealing nipple. In this embodiment, the sealing nipple 285 includes two sealing grooves, designated as sealing grooves 285a and 285b. In general, the coupling lock nipple 235 includes one or more sealing grooves.

[167] In this embodiment, the connecting pipe 290 is a faceted connecting pipe, since it includes two faces with intermittent curvature between them, and does not include a curved surface with continuous curvature, as discussed in more detail here. The faceted connecting pipe 290 includes a pipe surface. In this embodiment, the faceted connecting pipe 290 includes opposing edges 291 and 292 of the connecting pipe, opposite edges 293 and 294 of the connecting pipe, opposite edges 295 and 296 of the connecting pipe and opposite edges 297 and 298 of the connecting pipe. It should be noted that the faceted connecting pipe 290 includes eight faces as an illustration in this embodiment. However, typically a faceted connecting pipe 290 includes one or more faces. The number of faces of the faceted connecting pipe 290 corresponds to the number of faces of the faceted socket 260, so that the faceted socket 260 can receive a faceted connecting pipe 240.

[168] It should also be noted that the faces 291 and 293 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 293 and 295 of the connecting pipe may be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 295 and 297 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 297 and 292 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 292 and 294 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 294 and 296 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. The faces 296 and 298 of the connecting pipe can be angled relative to each other, so that the curvature of the faceted connecting pipe 290 is interrupted between them. Thus, the connecting pipe 290 may be a faceted connecting pipe.

[169] In this embodiment, the drill adapter 280 includes a groove for a connecting pin that extends through a facet of a faceted connecting pipe 283. In general, the adapter 280 of a drill lock may include one or more grooves for the connecting pins. In this embodiment, the drill joint adapter 280 includes two grooves for the connecting pins, which are designated as grooves 299a and 299b for the connecting pins. In this embodiment, the grooves 299a and 299b for the connecting pins are located opposite to each other, while the grooves 299a and 299b for the connecting pins are located near the faces 291 and 292 of the connecting pipe, respectively. In particular, the grooves 249a and 249b for the connecting pins pass through the edges 291 and 292 of the connecting pipe, respectively. The connecting pin grooves 299a and 299b pass through the connecting pipe faces 291 and 292, respectively, so that the connecting pin grooves 299a and 299b face the connecting pin pins 275a and 275b, respectively, when the faceted socket 260 receives the faceted connecting pipe 240, as discussed in more detail below.

[170] It should be noted that the groove 299a for the connecting pin can pass through the portion of the connecting faces 293 and 298. Additionally, the groove 299b for the connecting pin passes through the portion of the connecting faces 297 and 294. Thus, the adapter 280 of the drill joint includes a groove for the connecting a pin that passes through a faceted connecting pipe.

[171] In FIG. 13a shows a longitudinal section of a drill string 100c that includes a tool assembly 108c, wherein the tool assembly 108c includes a drill lock adapter 230 and a drill pipe tool joint 200 connected together, and FIG. 13b and 13b show enlarged portions of the drill string 100c of FIG. 13a. It should be noted that, in this embodiment, the drill pipe 110 is connected to the drill collar 200. In particular, a threaded locking nipple 119 (FIG. 2a) is connected to a threaded locking sleeve 203 (FIG. 9a). A threaded locking nipple 119 is connected to a threaded locking sleeve 203 so that the nipple thread 114 is screwed onto the coupling thread 204.

[172] In addition, drill pipe 120 may be coupled to a drill lock adapter 230. In this embodiment, the threaded lock sleeve 123 (FIG. 3a) is removed from the pipe body 121 and replaced with a drill lock adapter 230. In particular, the threaded lock sleeve 123 is removed from the pipe body 121 and the drill pipe adapter connecting pipe 234 is connected to the pipe body 121. The drill pipe adapter connecting pipe 234 is fastened to the pipe body 121, for example by welding, with a seal being formed between them.

[173] It should be noted that the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the drill pipe coupling 200 and the drill adapter 230. In particular, the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the internal channel 232 of the drill adapter and the internal channel 202 of the drill pipe coupling. In this way, material can pass between the inner channels 112 and 122 of the drill pipe through the inner channel 232 of the drill joint adapter and the inner channel 202 of the drill joint. As discussed in more detail above, the inner channel 232 of the drill adapter can pass through the adapter 230 of the drill, and the internal channel 202 of the drill collar passes through the drill collar 200.

[174] In this embodiment, the sealing elements 272 and 273 are connected to the sealing nipple 235. In particular, the sealing elements 272 and 273 carry a sealing nipple 235, while they pass through the sealing grooves 236a and 236b, respectively, as shown in FIG. 13c. Sealing elements 272 and 273 may be, for example, annular gaskets of circular cross-section of various types. It should be noted that, in some embodiments, the implementation of the drill adapter adapter 201 includes grooves opposite the sealing grooves 236a and 236b. However, in other embodiments, such as the variant indicated by arrow 118 in FIG. 13a, the drill lock adapter housing 201 does not include grooves opposed to the sealing grooves 236a and 236b.

[175] In this embodiment, a faceted nipple 239 (FIG. 10a) extends through the drill pipe tool sleeve housing 201 (FIG. 9a). In particular, the faceted connecting pipe 240 and the sealing nipple 235 pass through the inner channel 202 of the drill collar housing and the annular face 219 of the socket (Figs. 9c, 9d and 13b). The seal nipple 235 passes through the drill pipe tool housing 201, so that a seal is formed by the sealing elements 272 and 273 that cooperate with the seal on the inner periphery of the drill pipe tool body.

[176] The faceted connecting pipe 240 of the embodiment shown in FIG. 10a and 10b, passes through the drill pipe tool body 201, so that the faceted connecting pipe 240 faces the faceted socket 210 (Figs. 9c and 9d). In particular, the faceted connecting pipe 240 extends through the housing 201 of the drill collar, so that the faces 241, 242, 243, 244, 245, 246, 247 and 248 of the connecting pipe face the faces 211, 212, 213, 214, 215, 216, 217 and 218 sockets, respectively. In this embodiment, the faces 241, 242, 243, 244, 245, 246, 247 and 248 of the connecting pipe interact with the faces 211, 212, 213, 214, 215, 216, 217 and 218 of the socket, respectively, so that the rotation of the lock coupling 200 the drill pipe relative to the adapter 230 of the drill lock is restrained.

[177] In addition, the faceted connecting pipe 240 extends through the drill pipe drill collar housing 201, so that the locking pins (FIGS. 10a and 10b) 249a and 249b are facing the locking pin pins 225a and 225b (FIG. 9d) , respectively. The locking pin grooves 249a and 249b are facing the inner locking pin holes 225a and 225b, respectively, when the edges 241, 242, 243, 244, 245, 246, 247 and 248 of the connecting pipe face the edges 211, 212, 213, 214, 215, 216, 217 and 218 sockets, respectively.

[178] In this embodiment, the locking pin 270a passes through the inner hole 225a for the locking pin and the groove 249a for the locking pin. In some situations, the locking pin 270a passes through the inner hole 225a for the locking pin and the groove 249a for the locking pin when the locking pin passes through the opening 227a of the hole for the locking pin. In some situations, the locking pin 270a passes through the inner hole 225a for the locking pin and the groove 249a for the locking pin when the locking pin passes through the opening 228a of the hole for the locking pin.

[179] The movement between the drill lock adapter 230 and the drill pipe tool lock 200 may be restrained when the blocking pin 270a passes through the inner hole 225a for the blocking pin and the groove 249a for the blocking pin. In particular, the movement of the drill lock adapter 230 and the drill pipe tool lock 200 from each other can be restrained when the blocking pin 270a passes through the inner hole 225a for the blocking pin and the groove 249a for the blocking pin. The locking pin 270a may block the drill joint adapter 230 with the drill pipe tool joint 200, while blocking inhibits the movement of the drill tool adapter 230 and the drill tool lock 200 from each other.

[180] In the embodiment shown in FIG. 9c, 9d, 13b and 13c, the fastener 271a extends through the opening 226a of the fastener. The fastener 271a passes through the opening 226a of the fastener and interacts with the locking pin 270a. The fastener 271a cooperates with the locking pin 270a, restraining its movement through the inner hole 225a under the locking pin. Thus, an unacceptable movement of the locking pin 270a through the openings 227a and 228a of the hole for the locking pin and its exit from the inner hole 225a for the locking pin and the groove 249a for the locking pin becomes less likely. The movement between the drill lock adapter 230 and the drill pipe tool lock 200 may be less likely to be restrained when the blocking pin 270a leaves the inner hole 225a for the blocking pin and the groove 249a for the blocking pin. Thus, the locking pin 270a needs to be secured in the inner hole 225a for the locking pin and the slot 249a for the locking pin. The fastener 271a may be, for example, various types of clamping screws. As shown in FIG. 13b, the fastener 271a is recessed into the housing 201 of the drill collar so that it is not cut off.

[181] In this embodiment, the locking pin 270b passes through the inner hole 225b for the locking pin and the groove 249b for the locking pin. In some situations, the locking pin 270b passes through the inner hole 225b for the locking pin and the groove 249b for the locking pin when the locking pin passes through the opening 227b of the hole for the locking pin. In some situations, the locking pin 270b may pass through the inner hole 225b for the locking pin and the groove 249b for the locking pin when the locking pin passes through the opening 228b of the hole for the locking pin.

[182] The movement between the drill lock adapter 230 and the drill pipe tool lock 200 may be restrained by passing the locking pin 270b through the inner hole 225b under the locking pin and the groove 249b under the locking pin. In particular, the movement of the drill joint adapter 230 and the drill pipe key lock 200 from each other may be restrained when the blocking pin 270b passes through the inner hole 225b for the blocking pin and the groove 249b for the blocking pin. The locking pin 270b locks the drill joint adapter 230 with the drill pipe lock sleeve 200 when the lock pin restrains the movement of the drill lock adapter 230 and the drill pipe lock sleeve 200 from each other.

[183] In the embodiment shown in FIG. 9d and 13c, the fastener 271b passes through the opening 226b of the fastener. The fastener 271b passes through the opening 226b of the fastener and interacts with the locking pin 270b. The fastener 271b interacts with the locking pin 270b to prevent the locking pin from moving through the inner hole 225b under the locking pin. Thus, it becomes less likely that the locking pin 270b through the openings 227b and 228b of the opening for the locking pin becomes unacceptable and exits from the internal hole 225b for the locking pin and a groove 249b under the locking pin. Moving between the drill lock adapter 230 and the drill pipe tool lock 200 may be less likely to be restrained when the locking pin 270b leaves the inner hole 225b for the locking pin and the groove 249b for the locking pin. Thus, the locking pin 270b needs to be secured in the inner hole 225b for the locking pin and the slot 249b for the locking pin. The fastener 271b may be, for example, various types of clamping screws. The fastener 271b may be flush with the housing 201 of the drill collar, so that it is not possible to cut it off.

[184] In FIG. 14a is a longitudinal sectional view of an embodiment of a drill string 100d that includes a tool assembly 108d, wherein the tool assembly 108d includes a drill tool adapter 280 and a drill pipe tool nipple 250 connected together, and FIG. 14b and 14b show fragments of the drill string 100d of FIG. 14a. It should be noted that, in this embodiment, the drill pipe 120 is connected to the drill pipe tool nipple 250. In particular, the threaded locking nipple 253 (FIG. 11a) is screwed onto the threaded locking sleeve 123 (FIG. 3a). A threaded locking nipple 253 is connected to a threaded locking sleeve 123 so that the threaded nipple thread 254 is screwed onto the coupling thread 124 (Fig. 3a).

[185] In addition, drill pipe 110 may be coupled to a drill lock adapter 280. In this embodiment, a threaded locking nipple 119 (FIG. 2a) is removed from the pipe body 111 and replaced with a drill lock adapter 280. In particular, the threaded locking nipple 119 is removed from the pipe body 111, and the drill pipe adapter connection pipe 284 is connected to the pipe body 111. The drill pipe adapter connector 284 may be attached to the pipe body 111, for example, by welding, with a seal being formed between them.

[186] It should be noted that the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the drill pipe nipple 250 and the drill adapter 280. In particular, the inner channels 112 and 122 of the drill pipe can hydraulically communicate with each other through the inner channel 282 of the adapter of the drill joint and the inner channel 252 of the drill pipe nipple. Thus, the material can pass between the inner channels 112 and 122 of the drill pipe through the inner channel 282 of the adapter of the drill joint and the inner channel 252 of the locking nipple of the drill pipe. As discussed in more detail above, the inner channel 282 of the drill adapter can pass through the adapter 280 of the drill, and the internal channel 252 of the tool nipple of the drill pipe passes through the tool nipple 250 of the drill pipe.

[187] In this embodiment, the sealing elements 272 and 273 are connected to the sealing nipple 285. In particular, the sealing elements 272 and 273 carry the sealing nipple 285, while they pass through the sealing grooves 286a and 286b, respectively, as shown in FIG. 14c. Sealing elements 272 and 273 may be of various types, such as an o-ring. It should be noted that in some embodiments, the implementation of the adapter of the drill lock 251 includes grooves opposite the sealing grooves 286a and 286b. However, in other embodiments, such as the embodiment indicated by arrow 119 in FIG. 14a, the drill lock adapter housing 201 does not include grooves opposite to the sealing grooves 286a and 286b.

[188] In this embodiment, the faceted nipple 289 (FIG. 12a) extends through the drill pipe tool nipple body 251 (FIG. 11a). In particular, the faceted connecting pipe 290 and the sealing nipple 285 pass through the inner channel of the drill joint adapter 252 and the annular face 269 of the socket (Figs. 11a and 14b). The seal nipple 285 passes through the drill pipe tool body 251, so that a seal is formed by the sealing elements 272 and 273 that cooperate with the seal on the inner periphery of the drill pipe tool body 251.

[189] The faceted connecting pipe 290 (FIGS. 12a and 12b) can pass through the drill pipe tool body 251 so that the faceted connecting pipe 290 faces the faceted socket 260, as shown in FIG. 11a and 11b. In particular, the faceted connecting pipe 290 can pass through the drill pipe tool body 251 so that the edges 291, 292, 293, 294, 295, 296, 297 and 298 of the connecting pipe face the faces 261, 262, 263, 264, 265, 266, 267 and 268 sockets, respectively. In this embodiment, the faces 291, 292, 293, 294, 295, 296, 297 and 298 of the connecting pipe interact with the faces 261, 262, 263, 264, 265, 266, 267 and 268 of the socket, respectively, so that the rotation of the locking nipple 250 the drill pipe relative to the adapter 280 of the drill lock is restrained.

[190] Furthermore, the faceted connecting pipe 290 may extend through the drill pipe tool body 251 so that the locking pin grooves 299a and 299b (FIGS. 12a and 12b) are facing the locking pin pins 275a and 275b (FIG. 11b ), respectively. The locking pin grooves 299a and 299b can be inserted in front of the internal locking pin holes 275a and 275b, respectively, when the faces 291, 292, 293, 294, 295, 296, 297 and 298 of the connecting pipe face the faces 261, 262, 263, 264 , 265, 266, 267, and 268 nests, respectively.

[191] In this embodiment, the locking pin 270a passes through the inner hole 275a for the locking pin and the groove 299a for the locking pin. In some situations, the locking pin 270a passes through the inner hole 275a for the locking pin and the groove 299a for the locking pin when the locking pin passes through the opening 277a of the hole for the locking pin. In some situations, the locking pin 270a passes through the inner hole 275a for the locking pin and the groove 299a for the locking pin when the locking pin passes through the opening 278a of the hole for the locking pin.

[192] The movement between the drill lock adapter 280 and the drill pipe tool nipple 250 may be restrained when the blocking pin 270a passes through the inner hole 275a for the blocking pin and the groove 299a for the blocking pin. In particular, the movement of the drill joint adapter 280 and the drill pipe key nipple 250 from each other may be restrained when the blocking pin 270a passes through the inner hole 275a for the blocking pin and the groove 299a for the blocking pin. The locking pin 270a locks the drilllock adapter 280 with the drill pipe nipple 250 when the lock pin restrains the drill adapter 280 and the drill pipe drill nipple 250 from each other.

[193] In this embodiment, the fastener 271a extends through the opening 276a of the fastener (Figs. 11a, 11b, 14b and 14c). A fastener 271a extends through an aperture 276a of the fastener and interacts with a locking pin 270a. The fastener 271a cooperates with the locking pin 270a, restraining its movement through the inner hole 275a under the locking pin. Thus, an unacceptable movement of the locking pin 270a through the opening 277a and 278a of the hole for the locking pin and its exit from the internal hole 275a for the locking pin and the groove 299a for the locking pin becomes less likely. The movement between the drill lock adapter 280 and the drill pipe tool nipple 250 may be less likely to be restrained when the locking pin 270a leaves the inner hole 275a for the locking pin and the groove 299a for the locking pin. Thus, the locking pin 270a needs to be secured in the inner hole 275a for the locking pin and the slot 299a for the locking pin. The fastener 271a may be, for example, various types of clamping screws. As shown in FIG. 14b, the fastener 271a is recessed into the drill pipe tool nipple housing 251, so that it is not possible to cut it off.

[194] In this embodiment, the locking pin 270b passes through the inner hole 275b for the locking pin and the groove 299b for the locking pin. In some situations, the locking pin 270b passes through the inner hole 275b for the locking pin and the groove 299b for the locking pin when the locking pin passes through the opening 277b of the hole for the locking pin. In some situations, the locking pin 270b passes through the inner hole 275b for the locking pin and the groove 299b for the locking pin when the locking pin passes through the opening 278b of the hole for the locking pin.

[195] The movement between the drill lock adapter 280 and the drill pipe tool nipple 250 may be restrained when the blocking pin 270b passes through the inner hole 275b for the blocking pin and the groove 299b for the blocking pin. In particular, the movement of the drill lock adapter 280 and the drill pipe tool nipple 250 from each other can be restrained by the passage of the locking pin 270b through the internal hole 275b for the locking pin and the groove 299b for the locking pin. The locking pin 270b locks the drill adapter 280 with the drill pipe nipple 250 when it restrains the drill adapter 280 and the drill pipe drill nipple 250 from moving away from each other.

[196] In the embodiment shown in FIG. 11b and 14c, the fastener 271b passes through the opening 276b of the fastener. The fastener 271b passes through the opening 276b of the fastener and interacts with the locking pin 270b. The fastener 271b cooperates with the locking pin 270b, restraining its movement through the inner hole 275b under the locking pin. Thus, the unacceptable movement of the blocking pin 270b through the openings 277b and 278b of the hole for the blocking pin and its exit from the inner hole 275b for the blocking pin and the groove 299b for the blocking pin becomes less likely. Moving between the drill joint adapter 280 and the drill pipe tool nipple 250 may be less likely to be restrained by the release of the locking pin 270b from the inner hole 275b of the locking pin and the groove 299b of the locking pin. Thus, the locking pin 270b needs to be secured in the inner hole 225b for the locking pin and the slot 249b for the locking pin. The fastener 271b may be, for example, various types of clamping screws. The fastener 271b may be flush with the drill pipe tool nipple housing 251, so that it is not possible to cut it off.

[205] In this embodiment, the faceted socket 125a includes a curved socket surface 126 extending around the inner periphery of the drill joint adapter housing 131 and between opposite ends of the socket face 141. Nest surface 126 is a curved surface and is not a flat face like nest face 141. Thus, the faceted nest 125a includes one flat nest face that corresponds to the nest face 141. Socket 125a is a faceted socket because it includes the surface 126 of the socket.

[206] In this embodiment, the faceted socket 125b includes a drill joint adapter housing 131 with an inner passage 132 of the drill joint adapter passing therethrough. The faceted socket 125b includes an inner hole 135a for the locking pin and the openings 137a and 138a of the hole for the locking pin, as well as the opening 136 of the fastener, which are described in more detail above. Additionally, the faceted socket 125b includes an internal hole 135b for the locking pin and the openings 137b and 138b of the holes for the locking pin, as well as the opening 136 of the fastener, which are described in more detail above.

[207] In this embodiment, the faceted socket 125b includes a face 141 of the socket, with the inner hole 135a for the locking pin located near the edge 141 of the socket. In particular, the inner hole 135a for the locking pin passes through the edge 141 of the socket. The inner hole 135a for the locking pin opens into the inner channel 132 of the adapter of the drill lock. Socket face 141 is discussed in more detail above, and is shown in FIG. 4d. Face 141 nests is a flat face, and is not a curved surface.

[208] In this embodiment, the faceted socket 125b includes a face 142 of the socket, with the inner hole 135b for the locking pin located near the edge 142 of the socket. In particular, the inner hole 135b for the locking pin passes through the edge 142 of the socket. The inner hole 135b for the locking pin opens into the inner channel 132 of the adapter of the drill lock. Socket face 142 is discussed in more detail above, and is shown in FIG. 4d. Socket face 142 is a flat face, and is not a curved surface.

[209] In this embodiment, the faceted socket 125b includes a curved surface 126 of the socket that extends around the inner periphery of the drill lock adapter housing 131 and between the ends of the socket faces 141 and 142. The surface 126 of the nest is a curved surface and is not a flat face, as the face 141 of the nest.

[210] In this embodiment, the faceted socket 125b includes a curved surface 127 of the socket that extends around the inner periphery of the drill lock adapter housing 131 and between the ends of the socket faces 141 and 142.

[211] In FIG. 17 shows a portion of a replaceable nipple end of a drill pipe lock 170, a locking pin 270, a drill lock adapter 130, and a main body of the drill pipe 120. FIG. 17a shows an enlarged locking pin cooperating with a drill lock adapter and a drill pipe interchangeable lock nipple. As shown in FIG. 17a, the drill joint adapter and the interchangeable drill pipe key nipple may each include a groove having a semicircular section. When the pin interacts with both the interchangeable drill pipe tool nipple and the drill adapter, the assembly of the replaceable drill pipe tool adapter with the drill adapter is ensured by pushing the locking pin. Such a connection between the interchangeable drill pipe tool nipple and the drill lock adapter can provide a load distribution to the structure of both the locking pin and the shoulder of the drill adapter.

[212] The outer surface of the drill pipe tool joints and / or the drill tool adapter may include processing, coatings, and / or durability enhancing elements. For example, the outer surface of the drill pipe tool joints and / or drill tool adapter may include carbide weld deposits to minimize wear on the outside diameter and increase the service life of both the tool pipe locks and the main body of the pipe. Locking pins, holes for locking pins, polygonal nipples and polygonal couplings may also include processing, coatings and / or elements that improve durability. For example, a manganese phosphate conversion coating and subsequent post-treatment can be used to create a thin corrosion-resistant layer on the surface of the locking pins, holes for the locking pins, polygonal nipples, and / or polygonal couplings.

[213] As shown in FIG. 17A, a semicircular groove in the interchangeable drill pipe tool nipple is located slightly above the crescent groove in the drill pipe lock adapter. A tight slide-in installation can provide a bond when the locking pin snaps into place. A tight slide installation can create upward forces on the ledge of the drill joint adapter and downward forces on the ledge of the interchangeable drill pipe nipple. The forces at the junction between the interchangeable drill pipe tool nipple and the drill adapter are indicated by arrows 400. Connection ledges can provide a transfer of compressive load from the replaceable drill pipe tool nipple to the main body of the pipe.

[214] Advantages of embodiments of the invention may include reduced drill pipe repair time. Embodiments of the invention can also significantly reduce the cost of repairing drill pipes. Reducing repair time and cost can increase profitability with an increase in actual drilling time and a decrease in repair time and cost. Embodiments of the invention may also provide for replacing worn drill pipes at a remote drilling site using only conventional tools such as a hammer, punch, socket wrench, and / or angle grinder and other tools. In addition, embodiments of the invention can ensure that the production process meets environmental conditions since less fuel is consumed to deliver materials to be repaired at distances corresponding to remote sites. In addition, embodiments of the claimed invention can reduce smoke from welding, water consumption for flushing used drill pipes, and the release of contaminated water.
