Description
Technical field
The utility model, more particularly, to one kind for sucker-rod fishing tool in casing.
Background technique
Sucker rod pumping is widely used in foreign countries, and as oilfield exploitation difficulty is increasing, inclined shaft, deviated directional drilling are increasingly
More, pump is hung deeper and deeper.Sucker rod becomes increasingly complex in underground force status, and the factors such as pipe, the burn into eccentric wear of bar, fatigue are led
It causes pipe, the tripping of bar, disconnected de- phenomenon more frequent, causes to seriously affect to crude oil production.It is normally produced to restore oil well, need pair
The sucker rod fallen into well carries out fishing.
The sucker-rod fishing tool of field application is broadly divided into two classes at present:
One kind is tubular, such as three ball fishers, overshot with slot, Combined fishing cylinder.Their common feature is
Intracavitary realization is introduced into from junk top of fish end to salvage.When junk top of fish is complex-shaped or size is larger, then it can not salvage；
Two classes are that bar is hanging, are such as bent fisher, hook fishing tool.Hook fishing tool adapts to cyclic annular top of fish and salvages.
Bending fisher is not easily accessed salvaging mouth after cross section orthodrome sets right junk from structure.The reason is that cross section is short
Arm open outer side face is plane, and junk is stopped to enter.
Therefore, it is necessary on the basis of existing, design and laterally pumps in structurally reasonable, high construction efficiency the casing of one kind
Bar fishing tool.
Utility model content
Purpose of utility model: purpose of the utility model is to solve the deficiencies in the prior art.A kind of structure conjunction is provided
Reason, the fishing tool for laterally salvaging sucker rod junk top of fish of various shapes.The tool construction advantages of simple, it is easy to operate, beat
Fish out high success rate, reduction on-site construction processes, raising working efficiency.
Technical solution: in order to achieve the goal above, technical solution adopted in the utility model are as follows:
A kind of lateral sucker-rod fishing tool, including drill string connector, the connecting rod being connected with drill string connector, Yi Jiyu
The coupler body part of connecting rod connection,
The hook body segment point salvages structure including the cone cell that the shank side is arranged in a shank and one；
It includes two parts that the cone cell, which salvages structure, is respectively: a long-armed arc of shank bar wall side is arranged in
Guide portion, and a galianconism arc guide portion of the shank bar wall other side is set；
The long-armed arc guide portion and galianconism arc guide portion intersection form the cylindrical cavity of a lateral openings, described
The axis of the cylindrical cavity of lateral openings is parallel with the axis of the shank, also, the cylindrical cavity of the lateral openings is interior
Diameter is greater than the bar wall outer diameter of sucker rod, less than the outer diameter of rod collar.
The drill string connector, connecting rod and the connection of shank three's coaxial threaded.
The radian of the radian and internal surface of sleeve pipe of the long-armed arc guide portion is mutually fitted.
The top of the cylindrical cavity of the lateral openings is equipped with horn mouth.
The lateral sucker-rod fishing tool of the utility model compare with existing sucker-rod fishing tool, have below beneficial to effect
Fruit:
When salvaging junk, slowly transfer after visiting to top of fish to top of fish lower part.Anticlockwise drill string stirs top of fish and enters salvaging work
Have lower part cone cell to salvage in structure, is allocated at junk top of fish position laterally by the long-armed arc guide portion that cone cell salvages structure side
Inside, since the radius of arc guide portion is larger, when rotation, arc guide portion is almost the tube wall close to casing, it is possible to
Sundries most of in casing is salvaged, the sundries pushed in casing by long-armed arc guide portion is again by galianconism arc guide portion
The cylindrical cavity for leading into lateral openings, since the diameter of the cylindrical cavity design of lateral openings is between sucker rod bar diameter
Between the diameter of rod collar, sucker rod can be stuck, and then above mention drill string and arrest junk.
Drill string observation load variations are above proposed, judge whether to arrest junk.
When arresting, act drill string and fishing tool.
Drill string and left-handed to arresting junk is transferred when not arresting.
Lateral sucker-rod fishing tool described in the utility model is simple and reasonable, easy to operate, in casing
Sucker rod junk top of fish of various shapes easily arrests, fishing success ratio height, reduces on-site construction processes, improve working efficiency.
