Contracting, the deblocking of hydraulic pressure support device, tubing string pressure release.The utility model possesses following characteristics and function：（1）The tool construction is simple, makes
With conveniently；（2）The instrument is using hydraulic open and withdraws the structure supported, securely and reliably；（3）The instrument does not significantly alter
Former tubular column structure, simply increase small instruments and tools on former tubing string, on producing no any influence；（4）The instrument passes through in tubing string
Relevant position lay branch stake tool, improve the bending resistance of tubing string, greatly reduce down hole problem.
The utility model is nested with pushing block on the outside of the central tube on described between centrum and the ring-shaped step projection of fluid cylinder, uses
In promoting upper centrum to move down, efficiency is improved.
The utility model is nested with lock ring on the outside of the central tube below the pushing block, further enhances product performance, lock ring
It is locked on central tube, when hydraulic pressure reaches 10MPa, support block is fully extended, and lock ring can be locked on central tube, now lose hydraulic pressure
Also it can guarantee that support block stretches out support all the time.
The utility model is provided with the positive stop lug boss for being used for centrum on spacing in the upper end of support tube, ensures the both ends of support block
Inclined-plane can be brought into close contact with upper centrum and hypocentrum.
