Definitions

  • ABSTRACT A method for emplacing a production casing such as a 1 1 July 15, 1975 pipeline or other conduit beneath a surface obstacle such as a water course is disclosed.
  • a drill is provided which has a trailing drill string.
  • a pilot hole is drilled along an inverted arcuate path beneath a surface obstacle from one side to the other side of the obstacle so that the drill string occupies the pilot hole.
  • a reamer is provided which has a relatively smaller lead ing end and a larger trailing end. The leading end of the reamer is attached to one of the ends of the drill string, and an end of the production casing is attached to the trailing end of the reamer.
  • the production casing is thrust into the pilot hole at one side of the surface obstacle to project the reamer with the produc tion casing following into the pilot hole.
  • the drill string exits the pilot hole at the opposite side of the obstacle.
  • the reamer is operated by rotating the production casing or other method simultaneously with thrusting the production casing into the pilot hole to scarify and dislodge the earth circumscribing the pilot hole.
  • the pilot hole is enlarged to a diameter slightly greater than the production casing to provide an annulus between the production casing and the reamed hole.
  • Drilling mud is injected through the drill string to exit at the reamer where it entrains the dislodged earth.
  • the drilling mud containing the dislodged earth is allowed to flow into the annulus surrounding the production casing.
  • the present invention relates to a method for emplacing a production casing such as a pipeline or other conduit beneath a surface obstacle such as a water course.
  • the traditional method for laying pipelines, telephone cables and other underground conduits is to dig an open trench, lay the conduit in the trench and then close the trench.
  • This method is quite efficient in general, but problems arise when an obstacle such as a water course or a heavily traveled road is encountered, and the conduit must traverse the obstacle.
  • the road When a road is encountered, the road must either be closed, the traffic diverted, or parts of the road closed and the conduit laid in sections, all of which are inconvenient and interfere substantially with the use of the road.
  • a conduit When a conduit must span a water course, other problems arise.
  • the trench must be dug to a depth considerably below the level at which the conduit is to be laid since the current will partially fill the trench before the conduit can be inserted. This is a significant problem because such trenches have a generally triangular cross section, and the volume of dirt which must be removed increases with the square of the depth of the trench.
  • Such trenching also stirs the alluvium at the bottom of the water course interfering with the natural flora.
  • a second method is to attach a sled or skid to the leading end of the conduit, and drag this leading end through the trench to lay the conduit. With this method, the conduit must be coated with a substance to give it negative buoyancy, and this coating is quite expensive since the entire length of the conduit must be so coated.
  • the present invention relates to a method for emplacing a production casing such as a pipeline or other conduit under a surface obstacle.
  • a drill is provided having a trailing drill string.
  • a pilot hole is drilled along an inverted arcuate path beneath the obstacle from one side to the other so that the trailing drill string occupies the pilot hole.
  • a reamer is provided having a relatively small leading end and a relatively larger trailing end, and the leading end of the reamer is attached to one of the ends of the drill string.
  • the production casing is attached to the trailing end of the reamer.
  • the production casing is thrust into the pilot hole to project the reamer with the production casing following into the hole, and the drill string exits the pilot hole at the other side of the obstacle.
  • the reamer is rotated either by rotating the production casing or other method simultaneously with the thrusting of the production casing to operate the reamer to scarify and dislodge the earth surrounding the pilot hole.
  • the pilot hole is enlarged to a diameter at least equal to the diameter of the production casing so that the production casing is placed along the arcuate path as the pilot hole is being enlarged.
  • drilling mud is injected into the drill string so that it exits at the reamer.
  • the drilling mud thus entrains the earch scarified and dislodged by the reamer.
  • the pilot hole is reamed to a diameter slightly larger than that of the production casing and the drilling mud with the entrained earth therein flows into this annulus.
  • the drilling mud lubricates the production casing as it is thrust ino the hole so that friction on the production casing is minimized and there is no damage to the outer surface of the casing. Insertion of the production casing can be further facilitated by matching the buoyancy of the casing to the drilling mud and the casing will slip easily into the hole.
  • a relatively small return pipe is placed internal to the production casing, and is connected to the annulus around the casing. Drilling mud still fills the annulus to lubricate the production casing, but the excess drilling mud exits the hole through the return pipe so that the hole is not enlarged more than necessary and does not blow out, as described below.
  • the diameter of the return pipe can be selected so that the casing has neutral buoyancy and other weights are not required.
  • the reamer is non-rotatably attached to the production casing, and the production casing itself is rotated in order to operate the reamer.
  • This has the secondary advantage that the friction between the production casing and the sides of the hole is reduced because the casing rotates as it enters the hole.
  • the production casing is being placed along an arcuate path and the side walls of the casing are flexed upon each revolution of the casing. For larger diameter production casings, this flexing can cause fatigue failure.
  • an alternate embodiment of the present method is provided wherein the production casing is rotatably attached to the reamer, so that the casing does not rotate, and a drive shaft or other mechanism is employed to operate the reamer.
  • FIG. 1 is a perspective view of the completion of the pilot hole underneath the surface obstacle
  • FIG. 2 is a perspective view similar to that of FIG. 1 illustrating the reaming of the pilot hole to selected larger diameter;
  • FIG. 3 is a fragmentary elevation view of the reaming apparatus of the present invention.
  • FIG. 4 is a fragmentary elevation view of the reaming apparatus of the present invention partially cut away.
  • FIG. 5 is a fragmentary elevation view of an alternate embodiment of the present invention.
  • Drill string 20 comprises a plurality of interconnected drill string segments which are joined to form the drill string. After drill bit 18 emerges at the other side of obstacle 12, drill string 20 occupies the entire pilot hole 10.
  • production casing 32 is non-rotatably attached to the larger trailing end of reamer 30.
  • the production casing is forced into pilot hole 10 by thrusting the casing at its trailing end using drill rig l4, and reamer 30 is operated by rotating the casing.
  • Production casing 30 can be either a steel or cement pipe such as used for oil and water pipelines, protective casings for telephone lines and the like.
  • Production casing 32 consists of a plurality of segments such as 34.
  • a tube 36 is attached to the leading end of drill string 20.
  • Tube 36 is attached to a pump 38 which forces drilling mud through the drill string to exit at the reamer.
  • the segments are placed in a pile 40 and tube 36 is reattached to the leading end of the next segment.
  • drilling mud is continuously injected into pilot string 20 to exit at the reamer.
  • segments 34 of production casing 32 are added at the trailing end.
  • the drill rig 14 used for drilling the pilot hole also acts to thrust the production casing 32 into the ground in this embodiment as illustrated by arrow 42, and in the preferred embodiment rotates the production casing as well as operates the reamer.
  • reamer 30 is interposed between drill string 20 and production casing 32 in more detail in FIG. 3.
  • the narrower leading end of frustro-conical reamer 30 connects nonrotatably to drill string 20.
  • the larger trailing end of reamer 30 is nonrotatably connected to production casing 32.
  • Reamer 30 has a plurality of reamer teeth 42 which enlarge pilot hole 10 to a diameter slightly larger than that of production casing 32. This provides a small annulus 44 about the outer diameter of production casing 32.
  • Drilling mud which is injected through drill string 20 and exits at reamer 30 flows around the reamer and entrains the earth 46 scarified and dislodged by reamer teeth 42 as illustrated by arrows 48.
  • the drilling mud containing the dislodged earth flows into the annulus 44 circumscribing the production casing 32 as illustrated by arrows 50.
  • the used drilling mud serves to lubricate production casing 32 so that it slips easily into the enlarged hole.
  • the buoyancy of the production casing can be a critical problem. Since the density of production casing 32 with its hollow interior is substantially less than that of the drilling mud in annulus 44 for larger production casings, the production casing will be forced upwardly and will distort the path of the production casing as it is being emplaced. For smaller production casings, the density of the casing with its hollow interior is greater than that of the drilling mud and the weight of the casing distorts the path.
  • One of the features of the present invention is to weight the production casing 32 so that its density including the hollow interior is substantially equal to that of the drilling mud.
  • the production casing 32 will have neutral buoyancy with respect to the drilling mud and will slip easily into the hole along the axis of pilot hole 10.
  • neutral buoyancy can be achieved by placing foam inside the production casing, coating the casing, placing weights in the casing, and the like.
  • FIG. 4 A preferred embodiment of the present invention wherein excess drilling mud is removed as the production casing 32 is being emplaced is illustrated by way of reference to FIG. 4.
  • drilling mud is injected through drill string 20 as illustrated by arrow as previously shown.
  • This drilling mud exits at the reamer and flows into the annulus 44 around production casing 32.
  • an internal return pipe 62 is provided inside production casing 32.
  • Return pipe 62 has a plurality of extensions 64 which communicate with holes 66 in the walls of casing 32. In this manner, a connection is provided between return pipe 62 and annulus 44 so that excess drilling mud in the annulus can flow out through return pipe 62 as illustrated by arrow 68.
  • volumetric flow of drilling mud into the hole is generally greater than that which can be accommodated by annulus 44, failure to provide a return pipe such as 62 forces the drilling mud to flow backwardly along the production casing 32.
  • the pressure on the enlarged hole adjacent the reamer will be relatively large to force the mud along the entire casing.
  • the hole may blow out due to this pressure and water from the river can flow into the hole.
  • the excess drilling mud will flow into the water course and pollute the stream and destroy the natural wildlife.
  • the provision of return pipe 62 will avoid such a blow out when long production casings are emplaced.
  • a further advantage of the return pipe is that the diameter of the pipe can be selected so that the drilling mud will weight production casing 32 so that it has neutral buoyancy with respect to the drilling mud. Hence, a separate weighting mechanism need not be provided to achieve neutral buoyancy.
  • pipe 62 is used to return used drilling mud as illustrated by arrows 68.
  • a pipe such as 62 can be used to inject drilling mud so that it exits near reamer 30 rather than inject drilling mud through drill string 20.
  • pipe 62 would be extended as illustrated in phantom 69 so that the drilling mud would be injected at reamer 30 rather than into annulus 44. After the drilling mud entrains the earth scarified and dislodged by reamer 30, the used drilling mud flows into annulus 44 as in the previous embodiments.
  • FIG. 5 An alternate embodiment to those discussed above which is primarily adapted for use with relatively large production casings is illustrated in FIG. 5.
  • a production casing such as casing 70 has a diameter of greater than approximately inches
  • rotating the production casing in the arcuate path can cause excessive fatigue of the casing and it is preferred not to rotate the casing.
  • the casing is rotatably attached to the trailing end of a reamer such as 72.
  • the leading end of reamer 72 is nonrotatably attached to drill string 74, and drilling mud is injected through drill string 74 as illustrated by arrow 76, similar to the method described above.
  • reamer 72 is operated by means of a drive shaft 78 which rests along the bottom of casing 70.
  • a pulley 80 or gear arrangement is connected to reamer 72 so that rotation of drive shaft 78 operates the reamer.
  • a drilling motor as known in the art can be placed at the leading end of casing 70 to operate the reamer.
  • a return pipe such as return pipe 62 illustrated in FIG. 4, could also be provided.
  • the production casing 70 could be rotated slowly (relative to the rotation of the reamer 72) to make the casing slip more easily into the hole and reduce friction thereon. Fatigue of the casing is dependent upon the speed of rotation of the casing so that at low speed rotation may be acceptable where high speed rotation such as required to operate the reamer is not acceptable.
  • a method for emplacing a production casing beneath a surface obstacle such as water course comprising the steps of:
  • a method as recited in claim I wherein rotating the production casing to operate the reamer is adapted to enlarge the pilot hole to a diameter slightly larger than the diameter of the production casing to provide a narrow annulus circumscribing said production casing, said method additionally comprising the steps of injecting drilling mud into the end of the drill string opposite from the end of the drill string attached to the leading end of the reamer so that said drilling mud flows through said drill string to exit at the reamer; entraining in said drilling mud the earth scarified and dislodged by the reamer; and allowing the drilling mud containing the scarified earth to flow into the annulus around the production casing to lubricate the casing as it is forced into the pilot hole.
  • rotating the production casing to operate the reamer is adapted to enlarge the pilot hole to a diameter slightly larger than the diameter of the production casing, said method additionally comprising the steps of providing an inlet pipe internal to the production casing, said inlet pipe having one end terminating adjacent the reamer; injecting drilling mud into the inlet pipe so that said drilling mud flows through said inlet pipe to exit at the reamer; entraining in said drilling mud the earth scarified by the reamer; and allowing the drilling mud containing the scarified earth to flow into the annulus around the production casing.
  • attaching the leading end of the reamer to one of the ends of the drill string comprises attaching the leading end of the reamer to the end of the drill string at said first side of the surface obstacle.
  • a method as recited in claim 1 wherein said attaching the leading end of the reamer to one of the ends of the drill string comprises attaching the leading end of the reamer to the end of the drill string at said second side of the surface obstacle.
  • trailing drill string comprises a plurality of drill string segments, and additionally comprising the step of removing the segments individually from the drill string as said drill string segments exit the pilot hole at the opposite end of the obstacle.
  • a method for emplacing a large diameter production casing beneath a surface obstacle such as a water course comprising the steps of:
  • a method as recited in claim 10 wherein said providing means for rotating the reamer comprises the step of providing a drive shaft internal to the production casing, said drive shaft having a power output end attached to the reamer, and wherein said rotating the reamer step comprises rotating the reamer by rotating the drive shaft simultaneously with said forcing step to operate the reamer.
  • a method for emplacing a production casing beneath a surface obstacle such as a water course comprising the steps of: providing a drill having a trailing drill string; drilling a pilot hole along an inverted arcuate path beneath the surface obstacle from a first side to a second opposite side of the obstacle with said drill so that the trailing drill string occupies the pilot hole with the ends of said drill string being on opposite sides of the obstacle; providing a reamer having a relatively smallerleading end and a relatively larger trailing end; attaching the leading end of the reamer to one of the ends of the drill string; connecting an end of the production casing to the trailing end of the reamer; providing means for rotating the reamer; thrusting the production casing into the pilot hole to project the reamer with said production casing following into said pilot hole; rotating the reamer with rotating means simultaneously with said thrusting step to operate the reamer to scarify and dislodge the earth around the pilot hole; injecting drilling mud into the end of the drill string opposite from the end of
