Description

Hose reel for oil rig

Cross-reference paragraphs

This application claims benefit of U.S. non-provisional application No.15/656144 entitled "HOSE REEL FOR OIL RIGS" filed on 21.7.2017, the disclosure of which is incorporated herein by reference.

Background

Oil rigs have been used for many years to extract hydrocarbons from wells. Many of the techniques still in use today were developed years ago and are retained in today's drilling rigs simply because they are always the way they work. One example of this is the way in which fluids such as air, water, mud and cement are supplied to an oil rig. In a typical installation, the rig is placed at a location remote from the fluid sources and a hose is constructed to pump the fluids into and out of the rig. The hose is constructed of relatively short (about ten or twenty feet in length) hose and/or tubing sections. Each length is connected by a hammer nipple, which is performed by a person skilled in the drilling rig field. This approach is expensive in terms of time and other resources.

Disclosure of Invention

Various features are described herein to illustrate certain embodiments of the disclosure. In some embodiments, the present disclosure is directed to a hose reel for an oil rig. The reel may include a rotating drum having a central axis and a hose configured to be wound on the reel such that rotation of the drum causes the hose to be wound on or paid out from the reel. The hose is rated for pressures greater than 5,000 psi. The spool also includes a port arm coupled to the hose and configured to provide a fluid passage from the hose; and a spool port rotatably coupled to the port arm to allow the port arm to rotate with the rotating drum. In some embodiments, the hose reel is no greater than twelve feet tall and no greater than twelve feet wide to allow transport via truck using standard roads and minimal clearance.

Further embodiments of the present disclosure are directed to an oil rig including a base movable between wells, and a hose reel carried by the base. The hose reel is rotatable relative to the base. The hose reel may have a hose at least partially wound thereon and capable of being passively paid out as the base moves between wells. The length of the hose can be between 40 and 150 feet.

Yet another embodiment of the present disclosure is directed to a hose reel assembly that includes a base having a shaft and a rotating drum coupled to the shaft to allow the rotating drum to rotate about the shaft. The assembly may also have a hose length of between 40 and 150 feet and rated for pressures greater than 5,000 psi. Essentially the entire hose portion is wound in a single layer of coils around the rotating drum.

Detailed Description

Because of the many limitations inherent in operation, delivering fluids to an oil rig is a challenging proposition. In today's oil fields, wells are distributed in more varying patterns, including non-linear or grid patterns, whereas in the past few years, wells have been distributed in straight lines and the distances between wells have been larger. Previous approaches have used discrete, relatively short sections of hose that are joined together by hammering joints of pipe as the drill moves from well to well. This method may be effective if the holes are spaced such that the hoses and/or pipe sections match the distance between the wells. The hose section approach may also not be suitable for wells distributed in a non-linear arrangement because its ability to accommodate non-linear patterns is somewhat limited.

The four most commonly used fluids on oil rigs are air, water, mud, and cement, although the present disclosure is not limited to these fluids. For this reason, the present disclosure is not limited to use with oil rigs, and may be used in other fields, such as construction, military, fire fighting, agriculture, and the like. One challenge presented by cement and mud is that the hose is made of a more durable and pressure resistant material, the size of which exceeds that of other applications. In some embodiments, the hoses of the present disclosure are rated to maintain a pressure between 5,000 and 10,000 psi. They may have an outer diameter of 7 inches and an inner diameter of 2 inches. The hose may be made of braided steel and/or nylon material to support pressure and deleterious properties of the fluid, such as corrosiveness or toxicity. Thus, if these hoses are bent at a radius less than the prescribed minimum bend radius, they may be damaged. Some hoses cannot bend beyond their specified minimum bend radius at all. In addition, the hose is heavy enough that it is not possible to manually turn the reel around which the hose is wound without mechanical assistance in the form of a motor. With these parameters in mind, the length of the hoses of the present disclosure can be between 40 and 150 feet, thereby greatly reducing the amount of work and the time and resources required to operate the hoses on a drill rig.

Yet another limitation of the hose reel disclosed herein is transportation limitations. In the united states, many jurisdictions place restrictions on the height, width and weight of objects transported on roads. For example, many states limit the height of any trailer or truck to twelve feet high and twelve feet wide. Some of these limitations make the height of the enclosure no more than 16 feet, but they may require more expensive licenses and may have time limitations of a day/week, and even route limitations. Some bridges are not tall enough to transport some objects and so there is no license to modify this.

Fig. 1 is two isometric left and right illustrations of a hose reel 100 according to an embodiment of the present disclosure, wherein in both illustrations reference numerals are used for like indicators. Hose reel 100 includes a base 102, a shaft 104, and a drum 106. The drum 106 has two axially separated portions: a first portion 108 and a second portion 110. The two

portions

108 and 110 may be separated by a partition 112. The two

portions

108, 110 may have different diameters to accommodate hoses of different widths. In some embodiments, the total width of the spool 100 (including the spool, base, and trailer or truck) is no greater than twelve feet and the height is no greater than twelve feet, thereby allowing the trailer or truck to transport the spool 100 within common transportation limits.

The drum 106 may have an outer flange 114 on the outer circumference of the drum 106 to help hold the hose in place on the drum 106. The hoses are not shown here and will be shown later in this disclosure. In some embodiments, the two

portions

108 and 110 are used for hoses intended for different fluids. For example, the first portion 108 may be used for cement and the second portion 110 may be used for mud. The drum 106 may have a slot to accommodate loading of the drum 106 onto the shaft 104. The drum 106 may be riveted, bolted, welded or otherwise fastened to the shaft 104 such that the drum 106 can be rotated relative to the shaft 104 and bracket 102 to wind up or unwind the hose as desired.

The hose reel 100 also includes

fluid ports

118 and 120, one on each side of the reel 100. In some embodiments, a single port may be used on either side of the spool 100. In some embodiments, the

fluid ports

118, 120 are concentric with respect to the axle 104. The drum 106 may be rotated relative to the

fluid ports

118, 120 using a rotatable joint. Fluid may be pumped into the

fluid ports

118, 120. The

fluid ports

118, 120 are in fluid communication with the hose such that pumping fluid through the

ports

118, 120 causes fluid to enter and pass through the hose. The hoses and

fluid ports

118, 120 can be used to move fluid in either direction into the ports and then into the hoses, or from the hoses to the ports and then out of the spool 100.

The reel 100 also includes a motor 124 operatively connected to the shaft 104 and the drum 106 such that the motor 124 powers the rotational movement of the drum 106 relative to the base 102. The motor 124 may be an electric motor, a hydraulic motor, a pneumatic motor, or any other suitable power source configured to rotate the drum 106 to reel and reel the hose from the reel 100.

Fig. 2 is an exploded view of the spool 100 according to an embodiment of the present disclosure. The spool includes a port arm 129 that couples to an interior region of the port 118 shown in fig. 1. When assembled, the port arm 129 is positioned within the drum 106. The port arm 129 includes an axial portion 136, a plate 143, a bend 133, a radial portion 130, and a hose coupler 132. The plate 134 may be secured to the drum 106 at a central region. A bend 133 is coupled between the plate and the radial portion 130. Hose coupler 132 is coupled to radial portion 130 and the hose wound on drum 106. As the drum 106 rotates, the port arm 129 rotates therewith. Axial portion 136 may have a rotatable joint to allow port arm 129 to rotate relative to port 118. Axial portion 136 may have a hammer nipple coupling it to port 118, and a rotatable nipple may be located outside port 118. The axial portion 136 may have a machined surface that is located in the split bearing of the base 102. The base 102 may have a split pillow block bearing 131 or another suitable bearing to support the weight of the drum 106 and allow rotation. The plate 134 may have a drive sprocket mounted thereto that may be engaged by the motor 124. In some embodiments, the port arm 129 is hollow and directs fluid from the line entering the spool 100 and the hose wound onto the drum 106.

Spool 100 may have a second port arm 140, substantially similar to port arm 129, including an axial portion 150, a plate 148, a bend 146, a radial portion 142, and a hose coupler 144. The second port arm 140 may be configured for use with different materials and, therefore, may have different dimensions than the port arm 129. The motor 124 may be located on either side of the spool 100, or there may be two motors, one on each side.

In some embodiments, the

drum portions

108, 110 may be formed to rotate relative to each other to allow one hose to be paid out independently of the other. In this case, there may be two motors, one on each side, configured to move the

drum portions

108, 110.

Fig. 3 is a side view of the hose 160 and the port arm 129 according to an embodiment of the present disclosure. The drum, base and other components are hidden from view to highlight certain features. A portion of the hose 160 is unwound from the reel as shown at 162. The reel may be rotated in a counter-clockwise direction to pay out the hose as indicated by arrow a. As the spool rotates, the port arm 129 also rotates around the circumference of the spool so that fluid can be pumped through the hose 160. The port arm 129 includes a hose coupler 132 configured to receive a bend from the port arm 129 and into the wrapped hose portion. The size of the bend is driven by the constraint due to the pressure and other characteristics of the fluid in the hose 160.

Fig. 4 is a front view of a hose reel 100 according to an embodiment of the present disclosure. The reel 100 includes a base 102, a shaft 104, a drum 106 having a first portion 108 and a second portion 110, two port arms 129, and two corresponding hose couplings 132, which are generally similar to the features described in the other figures of the present disclosure. The reel 100 also shows two hoses leading to the reel 100: 166a and 168 a. These hoses are coupled to

spool hoses

166b and 168b, respectively. The hoses 166 and 168 are of different diameters to accommodate fluids having different requirements or being differently constrained. In some embodiments, the two fluids are cement and mud. The

portions

108 and 110 of the drum 106 are sized to accommodate the size difference. In some embodiments shown in the detailed section, the

drum portions

108 and 110 also differ in diameter to align the centerlines of the wound hoses 166B and 168B as shown by line B. In some embodiments, the first portion 108 carries mud in a seven inch diameter hose and the second portion 110 carries cement in a five inch diameter hose. The hose has a centerline that passes through the center of the hose when wound onto the drum 106. The diameters of the

drum portions

108 and 110 may be selected so that the centerlines of the two hoses are the same for both portions. In other words, the radius of the first drum portion 108 plus the radius of the hose carried by the first drum portion 108 is equal to the radius of the second drum portion 110 plus the radius of the hose carried by the second drum portion 110. These should not be construed as limiting examples. These dimensions may be selected to account for some deformation of the hose as it is wound onto the drum 106, or the hose may be such that there is little or negligible amount of deformation as it is wound onto the drum 106. In some embodiments, the hose has a length that is wrapped around the drum portion to form a layer of hose that just covers the surface of the drum 106, such that the centerline of the single layer hose coil is precisely known. In some embodiments, the hose has a diameter of seven inches and a length of about 150 feet, and the drum is about ten feet in diameter. In other embodiments, the minimum bend radius of the hose is five feet. Other embodiments include hoses or tubing between 2.26 "and 7.41" with pressure ratings between 5,000psi and 15,000psi and bend radii of 20 "to 60". The diameter of the spool ranges from 40 inches to 120 inches based on the bend radius.

Fig. 5 shows a top view of a hose reel assembly 100 according to an embodiment of the present disclosure. Similar to the other embodiments shown herein, the hose reel assembly 100 includes a base 102, a shaft 104, and a drum 106. The drum 106 may have two

portions

108 and 110 that may be selectively allowed to rotate relative to each other about the axis 104. In some embodiments, a pin or clutch may be used to selectively allow

drum portions

108 and 110 to rotate relative to each other. The assembly 100 also includes a conceptually illustrated motor 124 coupled to the bulkhead 112 between the two

drum portions

108, 110. The motor 124 may be selectively coupled to one or both drum portions to allow for selective powered rotation of the drum portions with power from the motor 124.

Fig. 6 illustrates a front view of a reel assembly 100 including a base 102, a shaft 104, and a drum 106, according to an embodiment of the present disclosure. The assembly 100 also shows a hose coupling 132 that is part of the port arm 129, shown to greater advantage in fig. 2 and 3. Note how the hose nipple 132 aligns with the location of the hose as it is wound onto the reel.

Fig. 7 is a side view of a hose reel assembly 100 according to further embodiments of the present disclosure. The assembly 100 has three detailed portions B, C and D. Detailed section B shows further details of the motor-drum interface. The drum has a hub 169 and a sprocket 170 fixed thereto or formed in the hub 169. The motor 124 is operably engaged with the sprocket 170 to rotate the spool. The shaft 104 may be supported by a split pillow block bearing 172 or other suitable mechanical fastener. Detailed portion C shows a switch 178 that is operatively coupled to the motor 124 and is configured to allow actuation of the motor 124. In some embodiments, the motor 124 may also operate as a brake, such as in the case of an electric motor. Detailed section D shows an interface 174 to allow access to the power of the motor 124. Fig. 7 also shows an enlarged view of the pin 176 which can be used to engage and disengage the motor from the drum 106 as desired.

Fig. 8 is an illustration of a hose reel assembly 200 in which the hose reel includes only a single drum portion, according to an embodiment of the present disclosure. Other aspects of the assembly 200 may be substantially similar to features described elsewhere herein.

Fig. 9 shows yet another embodiment of a hose reel assembly 300 according to an embodiment of the present disclosure. Fig. 9 shows a top view and a side view of the assembly 300. The assembly 300 includes a spool 302 and a skid 304. The skid 304 may be a platform configured to allow easy transport of the reel 302. The reel 302 may be fitted with bearings or rollers to rotate about a vertical axis to let the hose out at an angle relative to the rig. This is useful in situations where the drilling rig is moving along a non-linear pattern. In some embodiments, the drilling rig may be configured to allow passive release of one or more hoses as the drilling rig moves. This eliminates the need to manually construct the hose through the hammer nipple as before.

FIG. 10 is an illustration of a well pattern and rig movement scheme according to aspects of the present disclosure. An oil rig 200 is shown at three

different well sites

202, 204, and 206. The drilling rig 200 moves along a path 208 between the

wellsites

202 and 204 and along a path 210 between the

wellsites

204 and 206. The drilling rig 200 may be equipped with a hose reel according to embodiments of the present disclosure that allows relatively long hoses to be paid out as the drilling rig 200 is moved between wellsites. In some embodiments, the length of the hose may be between 0 and 150 feet. The hose is coupled to a fluid source 218. The fluid may be virtually any fluid. For many purposes, the fluid is one or more of air, water, cement, or mud. There may be a plurality of hoses, one or more for each fluid. As the drilling rig 200 moves to the first wellsite 202, the hose will be paid out along a line 212 reflecting the straight path through which the drilling rig reached the first wellsite 202. As the rig moves to the second wellsite 204, the hose continues to be played out passively or with some mechanical assistance, but since the second wellsite 204 is not aligned with the first wellsite 202, the hose will need to bend, as shown at 214. The hose reel of the present disclosure can be rotated to allow for this bending. Furthermore, the nature of using a single hose segment from a reel is more suitable for movement between non-linearly arranged wellsites. With the prior art, the hose would require manual construction of one 20-30 foot section at a time, requiring more time and resource expenditures than the techniques disclosed herein.

The foregoing description is given to highlight certain features of the present disclosure and any examples given are intended to be illustrative rather than limiting. Those of ordinary skill in the art will recognize that the features and aspects of the present disclosure are described in sufficient detail to enable them to be made and used without undue experimentation. It is to be understood that relative terms such as front, back, right, left, lower, etc., are given to aid in understanding certain drawings and are not to be used in a limiting sense.
