Definitions

  • the present invention pertains to production well completion to connecting well casings and their alignment to prevent thread and seal damage.
  • this invention relates to a casing alignment system comprising a head assembly having an open and a closed position, and roller assembly rotatably mounted on the head assembly for holding the casing.
  • a casing is designed to preserve the integrity of the well bore.
  • the casing is used as a conduit for well cementation and a pressurized container for production tubing.
  • A-casing section is normally a seamless steel tube approximately 12.2 meters in length, anywhere from 11.4 to 50.8 cm in diameter and may have a wall thickness in excess of 2.5 cm.
  • the casing section is normally threaded at each end with a collar screwed on to one end in preparation for placing in a well bore.
  • a well bore 4 is of a significantly larger diameter than the outer diameter of casing section 5 to allow easy placement down hole.
  • a casing section 5 is placed in an upright position and lowered partially down hole, with a collared end 6 extending above the ground surface surrounding well bore 4.
  • Casing section 5 is held in place by slips 7 secured to the surface to prevent casing section 5 from further descending well bore 4.
  • a second casing section 5A is stood upright with its uncollared end approximately in line with collared end 6 of the previous, partially downhole section 5.
  • Casing 5A is stood upright by a block arrangement 8 connected to a flexible cord 9 secured to casing 5A.
  • a crewman (not shown) is located on a platform 10 on a drilling rig 11 30 to 40 feet above the ground.
  • casing 5A When the casing 5A is vertical, he throws a rope around collared end 6A of casing section 5A and attempts to line it up with collar 6 of casing section 5. Hydraulic tongs (not shown) are connected to casing section 5A and it is rotated along its center line to screw into the exposed collar 6 of the previous casing section 5. Casing section 5A is lowered into well bore 4 and held in place by slips 7 which had been loosened to permit lowering of casing 5A and tightened to hold casing section 5A. The procedure is repeated until casing sections the length of the well bore have been put in place.
  • a casing section may weigh as much as 134 kg/m (90 pounds per foot). While the casing may be rated to hold 600 tonnes and the joint strength may be 80% or 480 tonnes, a joint made up having its threads damaged or galled will be significantly less. As a result, a joint may separate sending several thousand meters of casing downhole.
  • the present invention provides a method and apparatus for positive alignment of casing sections used to preserve the integrity of well bores.
  • a spoke yoke type is fixed to a drilling rig. The spoke is aligned with the center line of the well bore below.
  • a casing section is lifted vertically upright and brought near the yoke and lowered to touch the collar of the previous casing section. The yoke is closed, clamping the casing in position with rotatably mounted bearings positioned along the inner periphery of the yoke. The casing section may then be rotated to connect to the collar of the previous casing section.
  • Figure 1 illustrates a plan view of a casing alignment tool assembly as having a frame 13 with base member 14 angled support members 16 and centerpice 18. A portion of center member 18 extends past the intersection of angled members 16 and contains a pivot point 20. Attached at pivot point 20 is casing alignment tool 22 having head assembly 24, roller arm assemblies 26 and rollers 28. Illustrated in phantom are pneumatic cylinders 30, air pressure flowlines.32 and 34 and piston connections 36.
  • base member 14 of mounting frame 13 may be attached to any structure in close proximity to a pre-drilled well bpre, the only requirement being that the centerpoint defined by rollers 28 is capable of being aligned with the center of the well bore.
  • FIG. 2 a side view of the apparatus of Figure 1 is illustrated as having a pneumatic cylinder 40 attached to piston arm 42 which connects to curve member 44 of casing alignment tool 22.
  • Pivot point 20 is illustrated as a plurality of adjustment holes A, B, C, D, E, and F.
  • casing alignment tool 22 is illustrated as being pivotally mounted through adjustment hole F.
  • a device such as a block is lowered to the ground to attach to a casing section.
  • pneumatic cylinder 40 is activated to draw piston 42 within cylinder 40 thus drawing curved member 44 towards cross member 18.
  • pneumatic cylinder 40 draws piston member 42 within casing alignment tool 22 is elevated to provide clearances for a block to lift a casing section to an upright position.
  • Proper alingment may be selected by any method. For example, a plum line may be dropped from a centerpoint defined by rollers 28. However, the preferred embodiment positions casing alignment tool 22 after three or four sections of casing have been lowered to the bore hole. As indicated previously, casing sections may be put in place by the following method.
  • a casing section is raised to its vertical upright position by the use of a block and lowered into a bore hole to a point with an end of the casing section with a collar mounted thereon extending above the ground surface surrounding the bore hole.
  • Slips may be used to hold the first section of casing in position while a second section is raised to vertical upright position and lowered to the collar of the first section.
  • a crewman is located on a platform at the end of the second casing opposite the end and proximity of the collar of the first casing to align the center line of the second casing with the center line of the first casing. Hydraulic tongs may be attached to the uncollared end of the second casing to rotate the second casing and screw it into the collar of the first casing.
  • the slips may then be opened and the combination of the first and the second casing lowered into the bore hole.
  • the slips may then be closed to hold the collared end of the second casing in a position similar to that of the first casing to allow the addition of the third casing section.
  • the last casing is left in its extended position from the bore hole.
  • Casing alignment tool 22 may then be lowered and adjusted for proper centering on the well bore.
  • casing alignment tool 22 may be used for a variety of sizes of casing.
  • piston 36 is connected to roller arm 26 at hole 64, which is for a casing 22.86 cm in diameter.
  • hole 64 By connecting the end of piston 36 to hole 60, a casing 12.7 cm in diameter may be aligned.
  • hole 62 is for 17.78 cm diameter casing
  • hole 66 is for 27.3 cm diameter casing
  • hole 68 is for 33.97 cm diameter casing.
  • casing alignment tool 22 is lifted by pneumatic cylinder 40 to provide clearances for a block to be lowered to pick up a casing section.
  • the preferred embodiment uses a pneumatic cylinder with a 9.525 cm bore and an 45.72 cm working stroke.
  • a pneumatic cylinder with a 9.525 cm bore and an 45.72 cm working stroke.
  • Such a cylinder is marketed as a Miller Model A-84B (trademark).
  • any similar device such as an equivalent pneumatic or hydraulic cylinder or a solenoid may be used to maintain casing alignment 22 in a standby position.
  • casing alignment tool may be configured to withdraw to a standby position instead of being raised to a standby position.
  • roller arms 26 Prior to lowering casing alignment tool 22 to its alignment position, roller arms 26 are opened through pneumatic cylinders 30. Pneumatic cylinders 30 are operated by providing fluid pressure through fluid lines 34 urging pistons 36 to a withdrawn position rotating roller arms 26 to an open position.
  • casing alignment tool 22 When a casing has been elevated to a vertical upright position, casing alignment tool 22 may be lowered by pneumatic cylinder 40 through extension of piston arm 42. When casing alignment tool 22 is in its alignment position a casing section may be pulled against inner rollers 28 mounted on the fixed portion of casing alignment tool. When the casing section is in near proximity of inner rollers 28 pneumatic cylinders 30 may be energized through fluid pressure exerted through fluid line 32. Pressure exerted through fluid line 32 extend piston arms 36 drawing roller arms 26 to a closed position which clamps a casing section in a center of an area defined by rollers 28.
  • rollers 28 When a casing section has been clamped by rollers 28, hydraulic tongs or the like may be attached to the end of the casing section and rotate the clamped casing section into the collared end of a previous casing section. Rollers 28 are rotatably mounted on the stationary portion of casing alignment tool 22 and the roller arms 26 of casing alignment tool 22. Since rollers 28 are rotatably mounted, a casing section may be rotated freely to screw it in to the collared section of a previous casing section providing a positive accurately aligned seal.
  • Roller arms 26 illustrates two possible positions for rollers 28.
  • Position 70 may be used for rollers 28 or in casings having smaller outer diameter.
  • Hole 72 may be used for casings of greater diameter.
  • Hydraulic cylinders 30 may be of any type with sufficient strength to provide a positive clamp on casing sections by rollers 28 when energized.
  • Piston rods 36 are preferably made of stainless steel.
  • Rollers 28 may be of any type, however, those with nylon rollers with floating shafts are preferred.
  • the present invention provides a method and apparatus for eliminating air the problems inherent in misalignment of casing sections in bore hole casing placement.
  • casing sections may be accurately aligned without a great deal of time and expense.
  • Through the accurate alignment of the casing sections a great amount of time and money is saved.
  • the casing alignment tool of the present invention may be easily adapted to an angled bore hole by repositioning of casing alignment tool 22 or support frame 12.
