The utility model is related to a kind of waterpower can reversed sliding block.Its technical scheme is：Including top connection, shaft, closing piece, slips, shaft is connected in the bottom of top connection, inclined-plane key is provided with the middle and upper part of shaft and middle and lower part, slips is installed on inclined-plane key, it is characterized in that：Closing piece is fixed with by screw in the bottom of the inclined-plane key of the shaft middle and upper part, closing piece is fixed with by screw in the bottom of the inclined-plane key of the shaft middle and upper part, hole and spray-hole are communicated with closing piece, spray-hole is arranged on the outer end top of intercommunicating pore.The beneficial effects of the utility model are：When workover fluid flows through the utility model, partially liq enters reservoir through intercommunicating pore, liquid ejects through spray-hole along inclined-plane key direction in reservoir under differential pressure action, act on slips, slips is overcome to conduct oneself with dignity, shift slips onto inclined-plane key topmost, now slowly upper lifting pipe post disengages with junk inwall again, above carries instrument and exits junk.
Description
Technical field
It the utility model is related to one kind and drag for lance, more particularly to a kind of waterpower can reversed sliding block.
Background technology
Sliding block trip spear is a kind of conventional fishing tool, have it is simple to operate, salvage it is reliable, above carry tonnage it is big, can back-off,
The advantages that model is various, cheap, but due to its limitation in structure, sliding block trip spear can not move back after salvaging junk
Go out, unfreezing back-off is unsuccessful must to open safety joint, and many inconvenience are brought to subsequent construction, make it not adapt to salvage now
Need.Fishing tool exits to be needed to rotate tubing string mostly, is realized instrument and is exited, high angle hole, horizontal well tubing string frictional resistance
Greatly, moment of torsion can not be transmitted effectively, and because most instruments direction for needing when exiting to rotate with joint screw thread on the contrary, controlling bad
Turnning circle is easy for falling to dissipate by tubing string, so fishing tool be present exits problem.
The content of the invention
The purpose of this utility model is aiming at drawbacks described above existing for prior art, there is provided a kind of waterpower can back skating block drag for
Lance, salvage reliably, simple to operate, cheap, realizing instrument can move back.
Its technical scheme is：Including top connection, shaft, closing piece, slips, shaft is connected in the bottom of top connection, in shaft
Middle and upper part and middle and lower part be provided with inclined-plane key, slips is installed on inclined-plane key, it is characterized in that：In the oblique of the shaft middle and upper part
The bottom of face key is fixed with closing piece by screw, and lock is fixed with by screw in the bottom of the inclined-plane key of the shaft middle and upper part
Block, is communicated with hole and spray-hole on closing piece, and spray-hole is arranged on the outer end top of intercommunicating pore.
The center of above-mentioned shaft is provided with central ports, and described central ports connect with intercommunicating pore.
Above-mentioned face intercommunicating pore is provided with reservoir, and reservoir is shaped as annular.
Above-mentioned reservoir, intercommunicating pore and spray-hole is interconnected.
Direction injection of the injection direction of above-mentioned spray-hole along inclined-plane key.
The beneficial effects of the utility model are：The device is communicated with hole, reservoir and spray-hole, and workover fluid flows through this reality
With it is new when, partially liq enters reservoir through intercommunicating pore, in reservoir under differential pressure action liquid through spray-hole along inclined-plane key
Direction ejects, and acts on slips, overcomes slips to conduct oneself with dignity, and shifts slips onto inclined-plane key topmost, now slowly above carries again
Tubing string disengages with junk inwall, above carries instrument and exits junk.The utility model maintains the original feature of sliding block trip spear, is dragged for all
In lance class instrument, tonnage maximum is put forward on sliding block trip spear, is salvaged reliably, simple to operate, cheap, realizing instrument can move back.
It can prevent from salvaging the unsuccessful influence to caused by subsequent construction after opening safety joint originally；Solve horizontal well, high angle hole
Instrument exits problem, significantly improves salvaging efficiency, saves and receives other and can move back the expense of instrument.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
In figure：Top connection 1, shaft 2, closing piece 3, slips 4, intercommunicating pore 5, spray-hole 6, inclined-plane key 7, central ports 8, liquid storage
Groove 9.
Embodiment
With reference to accompanying drawing 1, the utility model will be further described：
The utility model includes top connection 1, shaft 2, closing piece 3, slips 4, shaft 2 is connected in the bottom of top connection 1, in lance
The middle and upper part and middle and lower part of bar 2 are provided with inclined-plane key 7, and slips 4 is provided with inclined-plane key 7, it is characterized in that：In the shaft 2
The bottom of the inclined-plane key 7 on top is fixed with closing piece 3 by screw, passes through spiral shell in the bottom of the inclined-plane key 7 of the middle and upper part of shaft 2
Nail is fixed with closing piece 3, hole 5 and spray-hole 6 is communicated with closing piece 3, spray-hole 6 is arranged on the outer end top of intercommunicating pore 5.
Wherein, the center of the shaft 2 is provided with central ports 8, and described central ports 8 connect with intercommunicating pore 5.
In addition, face intercommunicating pore 5 is provided with reservoir 9, reservoir 9 is shaped as annular.
In addition, described reservoir 9, intercommunicating pore 5 and spray-hole 6 are interconnected.
In addition, direction injection of the injection direction of described spray-hole 6 along inclined-plane key 7.
When salvage construction to oil-water well, if there is the situation for being unable to unfreezing and above carry, be unable to back-off, decentralization is salvaged
Tubing string, slips is set to be disengaged with junk inwall（Either turn an angle）, workover fluid by slush pump pressurization sleeve pipe in,
When workover fluid flows through the utility model, partially liq enters reservoir through intercommunicating pore, and liquid passes through in reservoir under differential pressure action
Spray-hole ejects along inclined-plane key direction, acts on slips, overcomes slips to conduct oneself with dignity, and shifts slips onto inclined-plane key topmost,
Now slowly upper lifting pipe post disengages with junk inwall again, above carries instrument and exits junk.
The utility model maintains the original feature of sliding block trip spear, drags for lance class instrument all, tonnage is carried on sliding block trip spear
Maximum, salvage reliably, simple to operate, cheap, realizing instrument can move back.It can prevent from salvaging originally and unsuccessful open safety
The influence to caused by subsequent construction after joint；Solve horizontal well, high angle hole instrument exits problem, salvaging efficiency is substantially carried
Height, save and receive other and can move back the expense of instrument.
It is described above, only it is preferred embodiment of the present utility model, any those skilled in the art may profit
Equivalent technical scheme is changed the utility model or is revised as with the technical scheme of above-mentioned elaboration.Therefore, foundation
Any simple modification or substitute equivalents that the technical solution of the utility model is carried out, belong to the greatest extent the requires of the utility model protection
Scope.
