The specific embodiment
As illustrated in fig. 1 and 2; The hydraulic releasing tool of the utility model; Comprise stop nut 1, shackle member 2, the adapter 3 of giving up, piston cylinder 4 and axle 5, stop nut 1, shackle member 2 and the adapter 3 of giving up are connected from top to bottom successively, axle 5 top and bottom have respectively and the step of the stop nut 1 and adapter 3 snap fit of giving up; Piston cylinder 4 be arranged on axle 5, stop nut 1 and the adapter 3 formed enclosure spaces of giving up in; Piston cylinder 4 leaves the mobile position that piston cylinder 4 moves down less than this enclosure space, and is fixed on the axle 5 through cutting off 42; The adapter 3 of giving up is provided with pressure transmission hole 31 and annular slot 32, and the elastic card claw 21 of shackle member 2 lower ends is fixed between piston cylinder 4 and the annular slot 32, and the shackle member 2 and the adapter 3 of giving up are connected to one.The section configuration of annular slot 32 is trapezoidal; As shown in Figure 4; Elastic card claw 21 for extend axially along shackle member 2, and the cantilever construction that can radially wobble along shackle member 2; Elastic card claw 21 free end external surfaces are provided with the trapezoidal convexity that can snap in the annular slot 32, and shackle member 2 circumferentially is uniformly distributed with and is provided with plurality of elastic claw 21.The shape of the trapezoidal convexity on the elastic card claw 21 is identical with the section configuration of annular slot 32, and the angle of the upper and lower side 321,322 of annular slot 32 trapezoidal cross-sections and adapter 3 axis of giving up all guarantees the positive lock to snapping in elastic card claw 21.Also be provided with claw tank 42 on the piston cylinder 4, piston cylinder 4 moves down to cut off and cuts off 42, and elastic card claw 21 falls into claw tank 42 shackle member 2 and the adapter of giving up were opened in 3 minutes.Because accident is slipped out of the hand in advance, the external surface of piston cylinder 3 also is provided with and cuts off 42 sheath 411 in order to prevent.
The operating process of the hydraulic releasing tool of the utility model is following:
1) hydraulic releasing tool that assembles is connected with oil reservoir protection safety valve top, all-pass footpath, is lowered to together in the producing well;
2) behind operating position, annular space is suppressed under, and pressure is through pressure transmission hole 31 on the adapter 3 of giving up; Act on the piston cylinder 4; Have to promote the trend that piston cylinder 4 moves downward,, cut off to cut off 42 when pressure is increased to certain value; Piston cylinder 4 moves downward, and elastic card claw 21 falls into the annular claw tank 42 of piston cylinder 5; Make shackle member 2 and give up and get loose between the adapter 3; Upper lifting pipe post, axle 5 are topped bar and are driven stop nut 1 and shackle member 2 moves upward, and tool string promptly breaks away from the adapter 3 of giving up, and completions of giving up protects safety valve to be positioned over the operating position with very little oil reservoir the hydraulic pressure adapter of giving up.
Further salvage the adapter 3 of giving up like need, as shown in Figure 3, can be lowered to recovery instrument 7, the convexity 33 through the grab 71 of recovery instrument 7 hooks the adapter 3 of giving up proposes tool string.
Because the oil reservoir of oil well bottom protection safety valve place has had packer 6, need not the pitching operation when therefore giving up operation, can realize building the pressure through packer 6.
It is to be noted that the foregoing description is exemplary the utility model is explained,, all should not think the protection domain that breaks away from the utility model according to any distortion that the spirit of the utility model is made.
