The utility model aims to solve when the dynamic logging of long-term production is under construction, adopt oil pipe transport technology operating time long, working strength is big, wastes time and expense the problem of expense cost of labor, provides a production logging instrument cable in pit and throws and drag for the instrument, should throw and drag for the instrument and change original process flow, improves work efficiency, reduces construction cost.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:
a production logging downhole instrument cable fishing tool comprises a tool outer sheath, a sliding locking release sleeve, a locking steel ball and a lead screw linear motor; the inner diameter of the lower part of the outer sheath of the tool is larger than that of the upper part; the sliding locking release sleeve, the locking steel ball and the screw rod linear motor are assembled in the outer sheath of the tool.
The utility model discloses further improvement lies in:
the lead screw linear motor is a polished rod.
When the fishing tool is in a grasping state, the screw rod linear motor drives the sliding locking release sleeve and the locking steel balls to move towards the small-diameter part at the upper part of the outer sheath of the tool, so that the locking steel balls are in a locking state, and the fishing head of the underground instrument or tool is locked.
When the fishing head needs to be separated from the cable fishing tool, the screw rod linear motor drives the sliding locking release sleeve and the locking steel balls to move towards the position with the large diameter at the lower part of the outer sheath of the tool, so that the locking steel balls are in a release state, and the release function of the underground instrument or the tool is realized.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model is simple in operation, safe and reliable, the effectual problem of wasting time and energy in having solved the work progress. Secondly, the utility model discloses simple structure, the reliability is high, can bear great pulling force, repeatedly usable. Finally, the utility model discloses change original process flow, improved work efficiency, reduce construction cost.
