Description
Technical field
The present invention relates to fisher in a kind of slip-type of coiled tubing fishing.
Background technology
In oil and gas industry, because field operation operating mode is complicated, on well fish may all occur at any time drops
The accident in shaft bottom.Fish shaft bottom of dropping has direct or indirect threat to Reservoir Development, hinders normal Reservoir Development
Work, great safety responsibility accident may be induced when serious, therefore it is extremely important in developing of reservoirs to salvage fish
Engineer operation project.Because the situation of fish is various, so also species is various for corresponding fishing tool, vary,
But fishing all requires efficiently promptly to salvage fish as far as possible, to save the normal production operation time, avoids more
Serious accident produces.A kind of current feasible method is to carry out fishing using coiled tubing, because coiled tubing is not deposited
Order very the problem of, lower going-into-well bottom can be continued, greatly save the time that fishing tool is gone into the well, therefore can be more efficiently fast
Fishing is carried out fastly.But due to coiled tubing be generally difficult to apply the pressure of the drill, therefore matched fishing tool should avoid by
Press operation.
The content of the invention
The purpose of the present invention is：In order to carry out efficiently quick fishing to underground tubing fish, spy provides one kind even
Fisher in continuous oil pipe slip-type.
In order to achieve the above object, the present invention uses following technical scheme：Fisher in a kind of coiled tubing slip-type,
It is to be made up of top connection, slips, slip spider, piston cylinder, main cylinder, spring, end cap and guide shoe；Its architectural feature is：Top connection
Upper end and coiled tubing screwed connection, top connection lower end and the screwed connection of main cylinder upper end；Top connection bottom is cylindrical to be uniformly arranged
Three slope grooves, slope groove both sides set fluted；It is circumferential in the middle part of main cylinder to be uniformly arranged outer space in three through hole connections
Between, a circle raised step is set below main cylinder middle through-hole；Slips outer surface of upper is arranged to zigzag, and sawtooth inclines upward
Tiltedly, slips top both sides are provided with raised outer rim, and slips bottom is arranged to T-shape hook；Slip spider upper end is circumferentially uniformly arranged
Three T-shape grooves, slip spider lower end and the screwed connection of piston cylinder upper end；The T-shape hook of three slips bottoms is arranged on card
In three T-shape grooves of watt seat upper end, three slips tops are arranged in the cylindrical slope groove in top connection bottom；Piston cylinder
Inner chamber top sets a circle raised step, piston cylinder lower end and end cap screwed connection；Spring is arranged under main cylinder middle through-hole
In the raised step of side, spring is in compressive state；Slip spider and piston-cylinder are on main cylinder is cylindrical；Guide shoe upper end and main cylinder
The screwed connection of body lower end, guide shoe lower end are arranged to spheroid.
The beneficial effects of the invention are as follows：(1) present invention is moved axially using hydraulic control piston cylinder to promote slips to open,
Control easy and effective；(2) present invention blocks tubing fish inwall using slips is stretched out, fixed reliable；(3) oil of the invention and continuous
Pipe connection uses, and can quickly realize tripping in and lifting, significantly saves the time of fishing.

Embodiment
As depicted in figs. 1 and 2, fisher in a kind of coiled tubing slip-type of the present invention, be by top connection 1, slips 2,
Slip spider 3, piston cylinder 4, main cylinder 5, spring 6, end cap 7 and guide shoe 8 are formed；Its architectural feature is：The upper end of top connection 1 and continuous
Oil pipe thread connects, the lower end of top connection 1 and the upper end screwed connection of main cylinder 5；The bottom of top connection 1 is cylindrical to be uniformly arranged three slopes
Groove, slope groove both sides set fluted；The middle part of main cylinder 5 is circumferential to be uniformly arranged three through hole connection interior or exterior spaces, main cylinder
One circle raised step is set below the middle through-hole of body 5；As shown in figure 3, the outer surface of upper of slips 2 is arranged to zigzag, sawtooth to
Inclined upward, the top both sides of slips 2 are provided with raised outer rim, and the bottom of slips 2 is arranged to T-shape hook；The upper end of slip spider 3 is circumferential
It is uniformly arranged three T-shape grooves, the lower end of slip spider 3 and the upper end screwed connection of piston cylinder 4；The T-shape of three bottoms of slips 2 is hung
Hook is arranged in three T-shape grooves of the upper end of slip spider 3, and three tops of slips 2 are arranged on the cylindrical slope in the bottom of top connection 1
In groove；The inner chamber top of piston cylinder 4 sets a circle raised step, the lower end of piston cylinder 4 and the screwed connection of end cap 7；Spring 6 is arranged on
In raised step below the middle through-hole of main cylinder 5, spring 6 is in compressive state；Slip spider 3 and piston cylinder 4 are enclosed on main cylinder 5
On cylindrical；The upper end of guide shoe 8 and the lower end screwed connection of main cylinder 5, the lower end of guide shoe 8 are arranged to spheroid.
A kind of coiled tubing of the present invention is with the operation principle of fisher in slip-type：Use the coiled tubing tripping in present invention
To fish top of fish, the present invention enters fish inner chamber in pipe under the guiding of guide shoe 8, is beaten by coiled tubing to inner chamber of the present invention
Pressure, slips 2 is protruding and clamping tubing fish inwall, above carries the i.e. recyclable fish of coiled tubing.
