The beneficial effects of the utility model are: one is that whole process only need descend one-trip string to complete packing job, reduces labour intensity, shortens the activity duration; Two when being flowlines, and hydraulic part and washing pipe take out with tubing string, stay well part few, are easy to salvage.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the first half of the present utility model;
Accompanying drawing 2 is structural representations of the latter half of the present utility model;
In upper figure: top connection 1, fluid cylinder 2, piston 3, anti-sit shear pin 4, retaining ring 5, thrust sleeve 6, setting shear pin 7, packing element 8, packing element cover 9, central tube 10, upper tapered sleeve 11, spring 12, slips 13, lower tapered sleeve 14, inner central tube 15, cover 16 of giving up, deblocking shear pin 17, shear pin 18 of giving up, adapter sleeve 19, adjusting rod 20, regulating sleeve 21, washing pipe joint 22.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises top connection 1, fluid cylinder 2, piston 3, anti-ly sit shear pin 4, thrust sleeve 6, setting shear pin 7, packing element 8, packing element cover 9, central tube 10, upper tapered sleeve 11, spring 12, slips 13, lower tapered sleeve 14, inner central tube 15, to give up cover 16, adapter sleeve 19, adjusting rod 20, regulating sleeve 21, washing pipe joint 22, by inner central tube 15, cover 16 of giving up is connected with lower tapered sleeve 14, spring 12 and slips 13 is placed between upper tapered sleeve 11 and lower tapered sleeve 14, piston 3 sits shear pin 4 the anti-of hydraulic action down cut bottom, promote anti-ly to sit thrust sleeve 6 on the downside of shear pin 4 and packing element cover 9, upper tapered sleeve 11 moves down, slips 13 circumference is stretched out, block internal surface of sleeve pipe, realize hanging, continue to apply pressure, the setting shear pin 7 on the downside of thrust sleeve 6 is cut off, and the packing element 8 that thrust sleeve 6 promotes downside compresses, and realizes packing, washing pipe joint 22 is connected to described gives up on cover 16, can rotate, cover 16 top of giving up is connected with top connection 1 by inner central tube 15, and bottom and washing pipe save 22 and be connected, and allowable stress in washing pipe joint 22, serves as filling passage, regulating sleeve 21 is after washing pipe joint 22 is connected with bottom washing pipe, plays regulatory role when connecting packer and screen casing, adjusting rod 20 coordinates with regulating sleeve 21, is connected to adapter sleeve 21 bottom.
Wherein, retaining ring 5 is provided with between piston 3 and thrust sleeve 6; The bottom of above-mentioned lower tapered sleeve 14 is provided with deblocking shear pin 17.
Said structure of the present utility model totally can be divided into hydraulic part, suspension packing part, give up part, adjustment portion; Entering down casing pack valve+screen casing in advance, and in screen casing under enter filling server with when being connected washing pipe, the washing pipe of this instrument joint 22 is connected with bottom washing pipe, then regulates regulating sleeve 21, packer is connected with screen casing; Precalculated position is arrived by under this instrument and lower tube string with oil pipe.First direct flushing, in oil pipe, drop into hollow steel ball again, when hollow steel ball is recycled to top connection 1 position, fluid cylinder 2, top connection 1 form hydraulic cavities with piston 3, build the pressure, piston 3 is cut off and is anti-ly sat shear pin 4, and piston 3 moves down, and promotes thrust sleeve 6 and packing element cover 9, tapered sleeve is moved down, slips 13 is released, is stuck on internal surface of sleeve pipe, realize hanging; Continue pressurization, setting shear pin 7 is cut off, and thrust sleeve 6 promotes packing element 8, packing element 8 is compressed, realizes packing, and retaining ring 5 locks upper tapered sleeve 11 and packing element 8 axial location, prevents from returning; Now suppress from well mouth oil pipe and casing annulus, checking sealing of packer packing effect.After pressure release, regulate oil pipe, weight indicator is indicated at oil pipe suspending weight, rotates forward oil pipe with pipe wrench, cut off shear pin 18 of giving up, rotate forward the cover 16 that makes to give up and be separated with adapter sleeve 19.On carry oil pipe 1-2 rice, carry out reacting cycle well-flushing, by hollow steel ball refunds ground.Again oil pipe is transferred, add suspending weight 1-2 ton, start packing job.After filling completes, oil pipe and washing pipe, filling server are proposed.Now complete packing job, produce.When needing to take out screen casing tubing string, with oil pipe band one fishing tool, lower to packer location, drag for central tube 10, above carry, deblocking shear pin 17 is cut off, central tube 10 moves, and retaining ring 5 unlocks, and packing element 8 recovers, upper tapered sleeve 11 is return under spring 12 acts on, slips 13 is return, and above puts and puts oil pipe for several times, guarantee removing seal for packer, propose oil pipe and screen casing tubing string, realize deblocking fishing.
Above-mentioned implementation method, suitably can adjust according to tool construction and field condition.
