Abstract
The invention discloses a kind of oil field well fishing junk devices, including connector, shaft, spring, circle slips, closing piece, screw, guide shoe, shaft is fixed on connector, circle slips is fixed in shaft by closing piece, the floating of the closing piece is adjustable pitch circle slips, the closing piece are fixed by screw, and the end of the shaft connects guide shoe, it is equipped with spring between the shaft and circle slips, is retractable structure in the middle part of the shaft.The configuration of the present invention is simple, flexible movements are reliable, easy to operation, and job success ratio is high, is hardly damaged top of fish, big with fish contact area, thus tension load is high, and anti-shock loading is big, is recycled.
Description
Technical field
The present invention relates to oil well marine salvage equipment, in particular to a kind of novel oilfield trouble of lost tool in hole fishing device.
Background technique
Currently used marine salvage equipment is probably divided into four for salvaging deep well bar and grabs fisher, salvages deep-well and bores
The mechnical oscillator of bar, cuts the novel cutter of tubulose fish, and can collect the flow type fisher of bulk landwaste and metal.
Junk, which cannot be salvaged, during salvaging comes, and can not exit, increase workover treatment difficulty, increase maintenance cost.
Summary of the invention
In view of the foregoing drawbacks or insufficient, the purpose of the present invention is to provide a kind of oil field well fishing junk devices.
The technical solution of the present invention is as follows:
Including connector, shaft, spring, circle slips, closing piece, screw, guide shoe, shaft is fixed on connector, and circle slips passes through
Closing piece is fixed in shaft, and the floating of the closing piece is adjustable pitch circle slips, the closing piece is fixed by screw, the lance
The end of bar connects guide shoe, and spring is equipped between the shaft and circle slips, is retractable structure in the middle part of the shaft.
The circle slips is connect with shaft by saw-tooth thread.
The invention has the benefit that
The configuration of the present invention is simple, flexible movements are reliable, easy to operation, and job success ratio is high, are hardly damaged top of fish, with
Fish contact area is big, thus tension load is high, and anti-shock loading is big, is recycled, and top of fish is rinsed, after catching junk, according to need
Be easy to exit junk, by using spring in junk internal diameter, in this way, even if spring falls off, due to size limitation not yet
It is easy to fall into well.And when salvaging heavier junk, the stress of spring has shared the stress of closing piece, to extend slips and lock
The service life of block increases the time of weight salvaging.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
As shown in Figure 1, oil field well fishing junk device provided by the invention, including connector 1, shaft 2, spring 3, circle card
Watt 4, closing piece 5, screw 6, guide shoe 7, shaft 2 are fixed on connector 1, and circle slips 4 being fixed in shaft 2 by closing piece 5, described
The adjustable round slips 4 of closing piece 5 floating, the closing piece 5 is fixed by screw 6, and the end connection of the shaft 2 is drawn
Shoes 7 are equipped with spring 3 between the shaft 2 and circle slips, be retractable structure in the middle part of the shaft 2.According to junk internal diameter I
Spring 3 can be used, in this way, even if spring falls off, since the limitation of size is also not easy to fall into well.And it salvages heavier
When junk, the stress of spring has shared the stress of closing piece, to extend the service life of slips and closing piece, increases weight and beats
The time of fishing.
In addition, circle slips 4 is connect with shaft 2 by saw-tooth thread.
Concrete operation method of the invention:
(1) according to the size of fish internal diameter, releasing spear adaptable therewith is selected.
(2) checking tool makes the axial movement value of round slips meet technical requirements.Make it close to release with hand rotation card
Ring, tool is in free state at this time.
(3) drilling tool is connected, down toward above 2m of top of fish or so, turn on pump recycles and slowly transfers drilling tool fish finding top.
(4) after visiting quasi- top of fish, examination mentions salvaging pipe and leans on and record suspending weight.
(5) formal to salvage.When fishing lance enters fish chamber, when suspending weight has decline to show, reversion drilling tool 1~2 encloses (field experience
Prove more turns it is a few circle also can) shaft to circle slips generate radial push, force shaft uplink, be that round slips blocks fish and fishes out
It obtains.
(6) drilling tool is above mentioned, if weight indicator suspending weight increases, it was demonstrated that fished out and obtained, can pull out of hole, if suspending weight does not increase, repeated
Aforesaid operations are until fishing obtains.
(7) when as above lifting power is close or larger than drilling tool safe load, shaft can be hit under drilling tool (or bumper sub), and just
It passes and mentions drilling tool upper after drilling tool 2~3 encloses, tool can be exited.
It salvages well and justifies slips outer diameter in a free state slightly larger than junk internal diameter.When tool enters fish chamber, circle slips quilt
Compression, generates certain outer expansion force, and round slips is made to be adjacent to junk inner wall.With shaft uplink and gradually increasing for power is lifted, shaft,
Saw-tooth thread matches mutually on circle slips, circle slips generate radial force, so that it is bitten fish and realize salvaging.When exiting once
Fish is stuck, can not pull out when need to exit fishing lance, if to shaft it is certain under hit power, can make inside and outside round slips and shaft
Saw-tooth thread disengages, then rotates forward the circle of drilling tool 2~3, and circle slips and shaft generate relative displacement, promotes round slips along shaft sawtooth
Shape screw thread moves downward, and until circle slips and release ring upper end face contact, above mentions drilling tool, can exit fish.
