Abstract
The utility model relates to a super expansion packer which is composed of a piston 1, a fishing outer sleeve 2, a pull rod 5, a fishing head 6, an expansion pipe 7, a seat sealing prevention pin 8, an unsealing pin 10, a lifting ring 14, a lock block 15, a sliding sleeve 17, rubber cylinders 18, a cone 22, a slip 23, a slip seat 24, a central shaft 25, a liner pipe 26, a press bearing head 27 and a sliding pin 28. The utility model adopts liquid transmission pressure to carry out seat sealing, the position of the seat sealing is provided with two rubber cylinders and four rubber cylinder protecting sleeves, the position of unsealing is connected by the pin and is provided with a sawtooth-shaped lock ring to prevent the unsealing, and fishing tools are connected in a screwed connection mode. When the utility model is used, the packer is connected with ground pipelines after being lowered to the position of the seat sealing to carry out pressurizing until the fishing tools are discarded, and the display pressure of a ground pump returns to zero at the time; when the seat sealing of the packer is finished, selective mining and cement injecting packing can be obtained. The utility model not only can solve the problems caused by sleeve pipe deformation but also can be used as a releasing gadget for plugging bottom water and a packer of sidetracked slim holes. The utility model has the advantages of reasonable design and simple structure, which is suitable for popularization and application on site.
Description
Technical field:
The utility model relates to the downhole tool that uses in a kind of field produces, particularly a kind of super swell packers.
Background technology:
At present, oil field benefit of all kinds of casing deformation well a few days increases, and the carrying out of measures such as the gas injection of heavy oil wells, high-solidifiability oil well, acidifying, pressure break especially aggravated the distortion of sleeve pipe or break.Add stage oilfield exploitation middle and later periods that is at present, each layer leakage is also very serious.Though The Application of Technology such as casing swage, sidetracking are arranged now, can not large tracts of land implement because of expense is expensive eventually, cause the accent layer of gas injection well, technical measures such as the bottom water plugging of oil well are carried less than on the schedule, have seriously influenced the exploitation rate of Liaohe Oil Field.
Technical scheme
The purpose of this utility model is to provide a kind of super swell packers, and this packer solves casing deformation, and the hole condition leakage seriously can not be annotated the problem that layer is transferred in grey shutoff, also can be as giving up to block up end water and side tracked slim hole packer.
The purpose of this utility model is to realize like this, it is by piston (1), salvage overcoat (2), interstage sleeve (3), staple (4), pull bar (5), fishing head (6), telescoping tube (7), the anti-pin (8) that sets, anti-setting sleeve (9), deblocking pin (10), stop collar (11), lock ring (12), pressure ring (13), lift ring (14), lock dog (15), baffle ring (16), sliding sleeve (17), packing element (18), packing element sheath (19), packing element axle (20), spacer ring (21), cone (22), slips (23), slip spider (24), central axis (25), bushing pipe (26), pressure bearing head (27), sliding pin (28), sliding pin staple (29) is formed, piston (1) and salvaging overcoat (2), fishing head (6), telescoping tube (7), lift ring (14), baffle ring (16) connects successively, interstage sleeve (3) and pull bar (5), central axis (25) connects successively, on central axis (25), be with anti-setting sleeve (9) successively, stop collar (11), lock ring (12), pressure ring (13), cone (22), slips (23), bushing pipe (26), sliding pin (28), there is the anti-pin (8) that sets fixing between anti-setting sleeve (9) and stop collar (11), stop collar (11) and lifting has deblocking pin (10) fixing between ring (14), lock dog (15) is arranged on packing element axle (20), sliding sleeve (17), packing element (18), packing element sheath (19), spacer ring (21), on bushing pipe (26), be with slip spider (24), pressure bearing head (27), sliding pin (28), sliding pin staple (29), fishing head (6) has staple (4) fixing with telescoping tube (7).
During work, central axis is connected with pull rod screw, piston, salvage overcoat, pull bar O shape cushion rubber slipper seal, when under the packer behind the precalculated position, connecting line is to the packer pressure of fetching water, and hydraulic pressure enters in the plunger shaft, because pull bar, central axis is motionless, fishing head, telescoping tube, lift ring, be that pin connects between the stop collar, stop collar moves downward with preventing common shearing of setting sleeve prevents setting pin, and after being cut off, cone moves downward, the slips spreading, be supported on the casing wall and fix, parts such as baffle ring continue the extruding packing element, and the packing element axle moves downward, packing element, it is big that packing element sheath radial diameter becomes, and formation sets.Fishing head wherein, telescoping tube lifts cover, and baffle ring pushes simultaneously and drives lock ring and move on central axis, when setting, lock ring has been moved to central axis buttless thread place, and lock ring endoporus and central axis be buttless thread simultaneously, both are linked together, can not counter motions, prevent deblocking.
The utility model is owing to adopt liquid transfering pressure to carry out the seat envelope, set the place and adopt two packing elements and four packing element sheaths, the deblocking place adopts pin to connect, and is provided with the zigzag lock ring and prevents deblocking, fishing tool adopts thread connecting mode, during work, packer behind seat envelope position, connects surface line and suppresses down, till instrument is lost, this moment, surface pump showed that pressure makes zero, and packer set finishes, and can divide and adopt and annotate grey packing.This instrument can seal big sleeve pipe and is celebrated with the minor diameter seat, can solve casing deformation, and the hole condition leakage is serious, can not annotate grey shutoff and transfer layer problem, also can use separately as the packer of giving up to block up end water and side tracked slim hole, it is reasonable in design, simple in structure, be well suited for field popularization application.
