Description
Technical field
Petroleum industry well workover fishing tool is the utility model is related to, specifically a kind of underground continuous oil pipe fishing is used
Cut and drag for integrated tool.
Background technology
As the well of coiled tubing construction operation is more and more, during continuous oil pipe operation, due to sand bury sand card,
The coiled tubings caused by reason such as trouble of lost tool in hole or dirt card, viscous crude or high-content wax oil card, casing damage card are disconnected de- or are stuck in well
Interior phenomenon happens occasionally, and the coiled tubing that at this moment we just need to fall into salvages.
At present, existing salvaging mode is salvaged by back-off, and still, due to the particularity of coiled tubing, pipe string is without connecing
Hoop, wall thickness are relatively thin and yielding, and when bit freezing occurs for coiled tubing, the bumper jar that coiled tubing can only be used to carry carries out jarring
Unfreezing, card can be caused to bury if unfreezing is unable to, and due to the heterogeneity of current continuous oil pipe operation, coiled tubing is in sand washing
In operation process, typically not with bumper jar；Unfreezing means is limited after coiled tubing generation bit freezing.
Meanwhile existing salvaging mode when the coiled tubing for not being broken completely is salvaged, it is necessary to first will be not complete
The coiled tubing being broken entirely, which is cut off, to be salvaged, it is necessary to which multiple tripping strings are salvaged, and which not only adds worker's
Labor intensity, while the cycle is longer, cost is higher, also, salvaged using existing conventional workover tool, to wellbore casing
Larger abrasion be present, so, a kind of fishing socket of new structure is badly in need of to solve these problems in scene.
The content of the invention
Goal of the invention of the present utility model is：For above-mentioned the deficiencies in the prior art, there is provided one kind salvaging cost is low, beats
Efficiency high is dragged for, reduces the number of tripping strings and reduces and cause cutting for abrasion to drag for coiled tubing integration salvaging to sleeve pipe
Cylinder.
Technical scheme is used by the utility model：A kind of underground continuous oil pipe fishing drags for integral chemical industry with cutting
Tool, including short circuit body, the inside of the short circuit body are from top to bottom sequentially disposed with locking lid, tension spring, drag for a watt assembly
With cutter assembly, it is described drag for watt assembly drag for watt seat and cutter assembly is fixed in short circuit body by shear pin respectively
Portion, the external diameter for dragging for the internal diameter of watt assembly in the quiescent state and being matched with underground continuous oil pipe, the cutter assembly is in the quiescent state
Internal diameter is matched with the external diameter of underground continuous oil pipe, and the inside of the short circuit body has the guiding being in below static cutter assembly
The conical surface.
Further, the short circuit body is provided with the cutter torsion pass screw for extending radially to inside, the cutter torsion pass
Screw is in above the guiding conical surface of short circuit body, and the inner of the cutter torsion pass screw is connected on the outer wall of cutter assembly.
Further, described drag for is provided with spacer ring between watt assembly and cutter assembly.
Further, watt assembly that drags for mainly is dragged for a watt cylinder, drags for watt and drags for a watt seat and formed by what axial order combined, described
Drag for the inwall of watt seat for ramp structure, there is the guiding conical surface to dragging for watt.
Further, described drag for watt is provided with spacer ring between assembly and tension spring, and the upper end of the tension spring abuts
It is connected in locking lid upper and lower end on spacer ring.
With further, the locking lid is tubular structure, and the tension spring is sleeved on the outer wall of locking lid.
Further, the upper end of the short circuit body with top connection, lower end with lower contact.
The beneficial effects of the utility model are：The utility model sets cutting to connect by the short circuit body interior in fishing socket
The cutter assembly of continuous oil pipe, after the coiled tubing being embedded in card in well is cut, the continuous oil that will be cut off by dragging for watt assembly
Pipe salvages well, effectively solves the problems, such as repeatedly to be salvaged tripping strings, so not only reduces the labor of worker
Fatigue resistance, effectively shorten and salvage the cycle, reduce salvaging cost, also, reduce the abrasion deposited to wellbore casing.
