Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Its technical scheme is：Including cylinder 3 and guide shoe, cylinder 3 and guide shoe are connected through a screw thread, the top of the cylinder 3
Provided with thread joint 1, the middle part of cylinder 3 cuts out the spring leaf 4 of three groups of different heights, and spring leaf 4 is trapezium structure,
Stretched out to cylinder lumen, the outer wall of cylinder 3 forms three groups of hollow out window arrangements, and the bottom of the cylinder 3 is flexibly connected serration type and drawn
One in footwear 5, semi-circular guide shoe 6 and wall hook formula guide shoe 7.
Above-mentioned serration type guide shoe 5 is made up of columnar guide shoe main body and sawtooth, in the bottom of columnar guide shoe main body
Offer a circle sawtooth.
Above-mentioned semi-circular guide shoe 6 forms overall structure by upper and lower two parts, and top is divided into columnar structured 6.1, lower part
For semi-cylindrical shaped structure 6.2, it is connected by upper part with cylinder 3.
Above-mentioned wall hook formula guide shoe 7 includes upper guide shoe main body 7.1, spiral shape wall hook 7.3 and opening 7.2, the upper guide shoe master
The top of body 7.1 is connected with cylinder 3, and bottom is provided with opening 7.2, and bottom is provided with spiral shape wall hook 7.3.
The external part of above-mentioned spring leaf 4 is provided with the anti-lost sawtooth 4.1 of 2-3 groups.
The spring leaf 4 of three groups of different heights in the horizontal direction according to interval 120 degree be uniformly distributed setting, and three groups of height
Degree is respectively separated 3-5cm.
In addition, thread joint 1 of the present utility model is located at the top of fishing socket, drilling rod box typically is used, it
Below be cylinder, thread joint and cylinder junction 2 can be screwed connections, and riveter is followed closely after can also being set with cylinder
Welding；
Cylinder typically makes of sleeve pipe, 10 millimeters of solderable sleeve pipe is less than using wall thickness, upper end connects with thread joint 1
Connect, lower end is the guide shoe of fishing socket；
Spring leaf cuts on fishing socket body and made.More than three layers of spring is opened in the different height for salvaging cylinder
Piece, the inscribed circle diameter of spring leaf should be less than salvaged 20-30 millimeters of junk external diameter depending on the size of salvaged junk
Between；The shape of guide shoe determines according to the state in well of shape and junk for salvaging junk, mainly have serration type, it is semi-circular and
Three kinds of wall hook formula.
The utility model is in use, specific as follows：
When needing to salvage shaft-like junk, in the utility model lower going-into-well, abundant circulating fluid, well inner product sand is cleaned,
Wellbore stability is kept, then transfers fish head；Pressure when being hampered mustn't exceed 5kN, as long as there is display, prevent that pressure is excessive
Guide shoe is squeezed into the borehole wall.
Serration type guide shoe is mainly used on junk and the more situation of sand setting around junk, sawtooth play remove sand setting and
Milling effect is covered, the gap of guide shoe and the borehole wall is less than 15 millimeters in this case, prevents fish head to be squeezed between guide shoe and the borehole wall,
Trip-out is considered as when entering fish head difficulty and changes semi-circular guide shoe.
When semi-circular guide shoe is salvaged, fish finding is transferred, after being hampered, one side of note enters, and lifts drill string, rotates 180 °, then past
Test, after being hampered, then remember that a side enters, the difference that two sides enter is exactly the discrepancy in elevation of guide shoe, and now selecting party enters that more
Position is that position test of the low side contact fish head of guide shoe, after being hampered, somewhat above carries 0.10~0.15m and rotates 180 ° again, its
Purpose is to allow the flash of guide shoe that fish head is introduced fishing socket, then transfers dipper, if the low side of guide shoe is not hampered, illustrates that fish has been drawn
Enter dipper, salvaging can be transferred, fish is entered within spring leaf can pull out of hole.
When wall hook formula guide shoe is salvaged, fish finding is transferred, after being hampered, one side of note enters, and lifts drill string, rotates 180 °, then past
Test, after being hampered, then remember that a side enters, the difference that two sides enter is exactly the discrepancy in elevation of wall hook, and now selecting party enters that more
Position is that position test of the low side contact fish head of guide shoe, after being hampered, somewhat above carries 0.10~0.15m and gently dials fish again, its
Purpose is to allow wall hook that fish head is introduced fishing socket, then transfers dipper, if the low side of guide shoe is not hampered, illustrates that fish has been introduced into dipper,
Salvaging can be transferred, fish is entered within spring leaf makes spring leaf block fish can to pull out of hole.
When salvaging shaft-like junk using the utility model, as long as judging that junk comes into dipper and just do not rotated easily again
Rotating disk, prevent spring leaf failure in rotation process or break.
The invention fishing success ratio is high and simple in construction, cost is cheap, and situ of drilling well, which can gather materials on the spot, to be processed, it is deep by
The welcome of situ of drilling well worker.
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.
