When using, a toper section of thick bamboo is connected through the T -slot with the slips, and during the oil pipe release, a toper section of thick bamboo goes upward under the effect of spring, and the slips is withdrawed, if the tubular column is transferred incomparable to disanchoring to the spring force, collude in involving outward, the tubular column lifts, withdraws the slips, collude in when and get into when restrainting the ring to collude in, and throw off with colluding outward, solved the limited spring force of spring effectively incomparable to the unfreezing to cause sticking of tool accident.

Description

A kind of oilfield downhole operation hydraulic anchor

Technical field

This utility model relates to technical field of petroleum extraction, particularly relates to a kind of oilfield downhole operation waterpower Anchor.

Background technology

Underground work is to ensure the technological means that oil-water well normally produces during In Oil Field Exploration And Development.Well Lower operation is to carry out in the wild, and mobility is big, and environment is arduous, and is the cooperation construction of many work posts；Well Lower operation danger is relatively big, keeps the post, closely cooperates, it is ensured that workmen's personal safety, equipment Safety and job execution safety.Underground work content mainly has oil-water well maintenance, oil-water well overhaul, oil Layer transformation and formation testing.

During oil field produces, when occurring in oil pipe building the pressure, act on internal surface of sleeve pipe by hydraulic anchor, it is achieved Grappling action.When suppressing from oil pipe, pressure promotes slips to snap on the inwall of sleeve pipe by slips, anti- Only tubing string displacement, it is achieved grappling effect, after release, slips is retracted under spring force, releases Grappling.Once slips is stuck with body, and the limited spring force of spring is not enough to unfreezing, thus causes card Brill accident.

Utility model content

This utility model is in order to overcome deficiency of the prior art, it is provided that a kind of oilfield downhole operation water Power anchor.

This utility model is to be achieved through the following technical solutions:

A kind of oilfield downhole operation hydraulic anchor, including body, described body include top connection, lower contact, Conically shaped, upper core pipe, lower core pipe, beam ring, outer hook, interior hook, slips, spring；Described spring One end is connected with interior hook, and the other end is connected with lower core pipe, and described conically shaped and described slips pass through T-shaped Groove is attached, and described conically shaped is connected with lower core pipe, one end of described lower contact and described slips phase Even, described beam ring is arranged between described upper core pipe and outer hook, and the outer wall of described upper core pipe is with described The inwall of lower core pipe is connected, and described top connection is attached with outer hook.

As optimal technical scheme of the present utility model, the outer surface of described slips has texture.

As optimal technical scheme of the present utility model, described lower contact is with described body by screw thread even Connecing, described top connection is threaded connection with described body.

As optimal technical scheme of the present utility model, described spring is helical spring.

Compared with prior art, the beneficial effects of the utility model are: this utility model in use, Suppress from oil pipe, lower core pipe slot feed liquor, promote conically shaped descending, push slips open, be used for bearing down The upper top power of facial canal post, conically shaped is attached by T-slot with slips, during oil pipe release, taper Cylinder is the most up, and slips is regained, if spring force is not enough to disanchor, transfers tubing string, Outer hooking hooks in living, upper lifting pipe post, is regained by slips, when interior hook enters beam ring, and interior hook and outer hook Disengage, efficiently solve the limited spring force of spring and be not enough to unfreezing, thus cause lock of tool drilling.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.

Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.

Described a kind of oilfield downhole operation hydraulic anchor, including body 1, described body 1 include top connection 2, Lower contact 3, conically shaped 4, upper core pipe 5, lower core pipe 6, beam ring 7, outer hook 8, interior hook 9, slips 10, spring 11；One end of described spring 11 is connected with interior hook 9, and the other end is connected with lower core pipe 6, Described conically shaped 4 is attached by T-slot with described slips 10, described conically shaped 4 and lower core pipe 6 are connected, and one end of described lower contact 3 is connected with described slips 10, and described beam ring 7 is arranged on described Between upper core pipe 5 and outer hook 8, and the inwall phase of the outer wall of described upper core pipe 5 and described lower core pipe 6 Even, described top connection 2 is attached with outer hook 8.

Described lower contact 3 is threaded connection with described body 1, described top connection 2 and described body 1 It is threaded connection.The outer surface of described slips 10 has texture, and described spring 11 is cylindrical bullet Spring.

In use, suppress from oil pipe, lower core pipe 5 slot feed liquor, promote conically shaped 4 descending, push away Opening slips 10, for bearing the upper top power of following tubing string, conically shaped 4 is entered by T-slot with slips 10 Row connects, and during oil pipe release, conically shaped 4 is up under the effect of spring 11, and slips 10 is regained, If spring force is not enough to disanchor, transferring tubing string, outer hook 8 tangles interior hook 9, and upper lifting pipe post, by slips 10 regain, and when interior hook 9 enters beam ring 7, interior hook 9 disengages with outer hook 8, efficiently solves bullet The limited spring force of spring is not enough to unfreezing, thus causes lock of tool drilling.

The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle Deng, within should be included in protection domain of the present utility model.
