Description
Technical Field
The utility model relates to a fishing tool field especially relates to an oil recovery well fishing tool.
Background
In the oil recovery well operation in-process, often the cable drops to in the well, claw formula overshot in the common use this moment, and the inside jack catch of traditional overshot is mostly the integral type, and it is difficult to dismantle, and the jack catch catches infirm with cable articulate department when upwards pulling after snatching the cable, and the structure is reasonable inadequately.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough to the above-mentioned that prior art exists, provide a rational in infrastructure oil recovery well fishing tool.
The utility model aims at realizing through the following technical scheme:
The utility model provides an oil production well fishing tool, includes the couple, an inner claw fishing barrel, hexagon socket head cap screw, the couple middle part has the cardboard, and the cardboard outside has a string tooth, hangs the inside arc wall that has of tooth, and the cardboard rear portion has the riser, and the riser top has the roof, riser middle part symmetric distribution baffle, and the riser bottom has an arc bottom plate, the inside symmetric distribution thread groove of riser, jack catch in the inner claw fishing barrel lower part evenly distributed, the inboard evenly distributed cardboard groove of inner jack catch, cardboard groove middle part have the riser groove, and riser groove top has the roof groove, riser groove outside symmetric distribution baffle groove, riser tank bottom portion have arc bottom plate groove, riser inslot symmetric distribution step screw hole, the cardboard is put into the cardboard inslot, and the baffle is put into the riser inslot, and the roof is put into the roof inslot, and the arc bottom plate is put into the arc bottom plate inslot.
The top of the inner claw overshot is provided with a connecting thread seat, the inner claw overshot is in threaded connection with a fishing cable through the connecting thread seat, an inner hexagon bolt is inserted into a step threaded hole and is in threaded connection with a threaded groove, and a hook is connected with the inner claw overshot.
Has the advantages that:
the arc wall is the partly of round hole, hangs the tooth and articulates the back with the cable, and the cable can hang and put in the arc wall, and it is difficult for upwards scurrying out, and is rational in infrastructure, and the roof is put into the roof inslot, and the riser is put into the riser inslot, and the arc bottom plate is put into the arc bottom plate inslot, and the baffle is put into the baffle inslot, and it cooperates mutually can evenly bear the gravity load that receives when carrying and the swing load that the cable dead weight caused when carrying, makes to connect firmly, and is rational in infrastructure.
