Abstract
The utility model relates to a fishing tool, in particular to a downhole catching fisher; the technical scheme of the downhole catching fisher is as follows: the downhole catching fisher mainly comprises an upper joint, an anti-blocking guiding cap, a slip mandrel, tooth sections, a pin and a restoring spring, wherein the upper joint is in threaded connection with the slip mandrel; the anti-blocking guiding cap is fixed at a connecting place between the slip mandrel and the upper joint; a rectangular slot is arranged under the slip mandrel; the tooth sections are fixed inside the rectangular slot by the pin and the restoring spring; the number of the tool sections is more than two groups; and the downhole catching fisher has the beneficial effects: the defects or shortcomings of the prior art can be effectively overcome or avoided, the downhole catching fisher is very well suitable for the downhole operation of barefoot wells, the unfreezing and fishing operation of the barefoot wells is effectively solved so that the downhole operation can be normally carried out, and the operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil field downhole tool, and the card fisher is grabbed in particularly a kind of down-hole.
Background technology
At present; In oil exploitation, open hole well is more and more, because the particularity of open hole well wellbore trajectory; So adopt conventional downhole tool just to exist many being inconvenient to reach very big risk to the open hole well well workover; Particularly, often cause down-hole accident complicated, influence the process of underground work for cable in open hole well and the sleeve pipe and various rope salvaging.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art; Provide a kind of down-hole to grab the card fisher; The shortcoming or the deficiency that can overcome effectively or avoid existing in the above-mentioned prior art; Adapt to the underground work of open hole well well, solve the operation of open hole well unfreezing fishing effectively, underground work is normally carried out.
Its technical scheme is: mainly draw cap, slips mandrel, tooth sheet, pin, back-moving spring by top connection, anti-sticking and form; Top connection is through the slips mandrel that is threaded; Cap is drawn in the junction of slips mandrel and top connection fixedly anti-sticking; The below of described slips mandrel is provided with rectangular slot, passes through fixedly tooth sheet of pin and back-moving spring in the rectangular slot, and described tooth sheet is more than two groups.
The bottom of above-mentioned slips mandrel is provided with guide shoe.
The beneficial effect of the utility model is: the shortcoming or the deficiency that can overcome effectively or avoid existing in the above-mentioned prior art; Adapt to the underground work of open hole well well; Solve the operation of open hole well unfreezing fishing effectively, underground work is normally carried out, improve job run efficient.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: top connection 1, anti-sticking draw cap 2, slips mandrel 3, tooth sheet 4, pin 5, back-moving spring 6, guide shoe 7.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly draws cap 2, slips mandrel 3, tooth sheet 4, pin 5, back-moving spring 6 and guide shoe 7 by top connection 1, anti-sticking and forms; Top connection 1 is through the slips mandrel 3 that is threaded; Cap 2 is drawn in the junction of slips mandrel 3 and top connection 1 fixedly anti-sticking; The below of described slips mandrel 3 is provided with rectangular slot, passes through fixedly tooth sheet 4 of pin 5 and back-moving spring 6 in the rectangular slot, and described tooth sheet 4 is more than two groups; The bottom of above-mentioned slips mandrel 3 is provided with guide shoe 7.
During use, when the tooth sheet passes trouble of lost tool in hole, rely on the elastic force of back-moving spring that the tooth sheet is ejected; Realization is fished for junk; The shortcoming or the deficiency that can overcome effectively or avoid existing in the above-mentioned prior art adapt to the underground work of open hole well well, solve the operation of open hole well unfreezing fishing effectively; Underground work is normally carried out, improved job run efficient.
