Description
Technical field
The utility model relates to down-hole bit freezing handling implement, particularly a kind of down-hole unfreezing hydraulic force increasing device, uses in the process construction of the lock of tool drilling such as drilling well, well workover.
Background technology
In drilling well, workover operation construction, due to reasons such as property of drilling fluid, geological conditions and long-term large intensity exploitations, rock cementing strength reduced or destroys, formation sand production or cave in, causing down-hole bit freezing phenomenon.Particularly in oil field development, oil field development is to the middle and later periods, long-term injecting water exploitation accelerates the reduction of development well section formation cementation intensity, and the phenomenon of formation sand production card flow string constantly rises, and separate desanding card flow string most economical, efficiently way be---activity unfreezing.This type of instrument being applied to job site at present has hydraulic force increasing device and bumper jar.The hydraulic force increasing device of current use can only realize to stuck point energetically on carry, cannot jarring releasing be realized.And bumper jar can only be applied with lift power by ground installation and produces jarring, but along with the raising of drilling technology, high angle hole, horizontal well constantly increase, make only by ground installation energetically on carry, the difficulty of activity unfreezing constantly increases.Particularly high angle hole, horizontal well are by Well Deflection Influence, the strength of ground installation activity unfreezing cannot normal delivery to the bumper jar of down-hole and stuck point, unfreezing effect is decline extremely, has had a strong impact on the process of down-hole lock of tool drilling, even caused producing well to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of down-hole unfreezing hydraulic force increasing device, the down-hole unfreezing hydraulic force increasing device of a kind of dependable performance, use safety.By hydraulic conduction mode, active force is directly delivered to release device, improves unfreezing effect, reduce cost of production.
The utility model is achieved in that a kind of down-hole unfreezing hydraulic force increasing device comprises housing and piston rod, housing is provided with pressure relief opening, piston rod is provided with inlet opening, piston rod is arranged in housing, the interior of housing is provided with flowing hole every platform, and the piston rod between inlet opening and flowing hole is equipped with spool.
Remarkable result of the present utility model is: the utility model is connected with operating tool string and applies hydraulic pressure from operating tool string, the active force that the utility model and the bumper jar that is connected with weighted lever produce is applied directly to stuck point place, than the movable operating tool string of dependence ground installation to the mode of down-hole fish unfreezing, its effect is direct, active force is unattenuated, Be very effective.On the other hand, use the utility model, when ground installation normally runs, jarring incessantly can be carried out to stuck point, directly, jarring afterburning at stuck point place can be reached and loosen stuck point, improve the object of unfreezing effect.Moreover, while realizing moment of torsion, pulling force, jarring force normal delivery, by the weighted lever of below connection and bumper jar, the inner chamber to stuck pipe post or instrument rinses cleaning to the utility model, facilitates fishing tool to salvage, also improves salvaging efficiency; And the liquid after pressure release has suspension, takes sand effect, also improve unfreezing efficiency, there is good result of use.It is simple that the utility model has structure, combines the feature of convenient, easy processing, and the scope of application is large, safe and reliable.Good result of use is all had to the lock of tool drilling process occurred in drilling well, workover operation construction.Because hydraulic conduction makes jarring of the present utility model, boosting function not by the impact of wellbore shape, especially for process high angle hole, horizontal well tubing string sand card accident, its effect is more obvious, and economic benefit is more remarkable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is connected to operating tool string structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: see Fig. 1, a kind of down-hole unfreezing hydraulic force increasing device, comprise housing 4 and piston rod 5, housing 4 is provided with pressure relief opening 8, piston rod 5 is provided with inlet opening 1, piston rod 5 is arranged in housing 4, and the interior of housing 4 is provided with flowing hole 7 every platform, and the piston rod 5 between inlet opening 1 and flowing hole 7 is equipped with spool 3.Pressure relief opening 8 is located on the shell wall of low pressure chamber 9 of housing 4, and flowing hole 7 is located at the periphery every platform centre bore in housing 4; Inlet opening 1 on piston rod 5 is just right with the high pressure chest 2 of housing 4; Inlet opening 1, high pressure chest 2, flowing hole 7, low pressure chamber 9 and pressure relief opening 8 form pressure release passage.Spool 3 is T-shaped sleeves, and be set on piston rod 5, its bigger diameter end is placed in high pressure chest 2, and its miner diameter end is inserted in housing 4 in the centre bore of platform, and spool 3 can slide on piston rod 5, bigger diameter end and interior between platform mounting spring 6.The external diameter of spool 3 bigger diameter end is less than the internal diameter of housing 4, and form pressure release annular space, the top cylindrical of bigger diameter end is provided with arc angling and coordinates with the spacing shoulder of housing 4, forms linear sealing, can close pressure release passage.Pressure relief opening 8, flowing hole 7 and inlet opening 1 are at least provided with three.Housing 4 inner circle two ends are provided with screw thread, and upper end is connected with hydraulic anchor 11 and operating tool string 10 successively by joint, and lower end is connected with weighted lever 12, bumper jar 13 and fishing tool 14 successively by joint.
See Fig. 2, in use, inject construction liquid by operating tool string 10 and rinse cleaning fish chamber or top of fish, pressurization or pressurization rotate operating tool string 10, make fishing tool 14 engagement with the fish.Carry operating tool string 10 suitably, make the utility model bear certain pulling force.Then, inject construction liquid, first distending hydraulic anchor 11 by operating tool string 10, make it to clench internal surface of sleeve pipe.Continue to improve pump pressure, hydraulic force increasing device starts, and bumper jar 13 starts energy accumulation, also applies corresponding pulling force to stuck point simultaneously.When pump pressure rises to setting numerical value, the spool 3 of hydraulic force increasing device inside starts, hydraulic force increasing device quick pressure releasing, and potential energy accumulated by bumper jar 13 fast release institute, and the kinetic energy changing weighted lever 12 into impacts fish stuck point; Meanwhile, the spool 3 of hydraulic force increasing device inside is closed.Subsequently, hydraulic force increasing device will start again, repeat a process.Realize the object of underground hydraulic pressure jarring releasing.
In use, high-pressure fluid enters high pressure chest 2 through the inlet opening 1 of hydraulic force increasing device, promotes piston rod 5 and moves up, realize down-hole reinforcement.When pressure rises to setting value, spool 3 under the effect of piston rod 5 and spring 6 fast on move, high-pressure fluid is through pressure release passage quick pressure releasing, and piston rod 5 moves down fast; When the near setting value of pressure, spool 3 moves down fast under the drive of piston rod 5, closes pressure release passage, that is, quick closedown spool 3, completes a cyclic process.Then, high-pressure fluid enters high pressure chest 2 through inlet opening 1 again, starts next circulation.
