Abstract

The utility model relates to a downhole tool used in an oil field, in particular to a multifunctional drift well gauge tool. The technical proposal is as below: the drift well gauge tool comprises a drift well gauge tool body, the bottom of which is provided with saw teeth, wherein, the inner wall of the drift well gauge tool body which is 10 to 30cm away from the bottom is provided with a plurality of triangular barbs inclining inwards. The multifunctional drift well gauge tool has the advantage that the mill sleeving and the sand washing are convenient, thereby saving the time and improving the work efficiency; when a drift well pipe is retained, the well can be circularly washed so as to facilitate the treatment of accidents; the multifunctional drift well gauge tool has simple structure and easy operation.

Description

Multi-functional drift size gauge tool

One, technical field:

The utility model relates to a kind of oil field downhole tool, particularly relates to a kind of multi-functional drift size gauge tool.

Two, background technology:

At present, the function of existing drift size gauge tool mainly is: 1, finish foreign material such as scraping internal surface of sleeve pipe burr, fouling, scale; 2, the sand post is lower than under the prerequisite of 50-100m, when recoiling the sand washing well operations, easily causes tubing string because of repeatedly removing the wearing and tearing of screw thread, simultaneously, and shortcomings such as activity duration length, operating worker labour intensity height, operating cost expense height.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of multi-functional drift size gauge tool that tubing string is short because of the wearing and tearing, the activity duration that repeatedly remove screw thread, alleviate operating worker labour intensity, saving operating cost expense of avoiding is provided.

Its technical scheme is: comprise the drift size gauge tool main body, in the bottom of drift size gauge tool main body sawtooth is set, wherein, the inwall of 10-30 centimetre drift size gauge tool main body is provided with the barb of a plurality of triangles in the distance bottom, and barb slopes inwardly.

Preferred scheme is that described barb is three isosceles triangles, be evenly distributed on the inwall of drift size gauge tool main body, and the inwall of the drift angle of isosceles triangle and drift size gauge tool main body is 30 degree angles.

The beneficial effects of the utility model are: by bottom hard sawtooth is set at existing drift size gauge tool, cover mill the sand washing construction convenient, not only save time but also increase work efficiency.When the drifting tubing string is met card, can anti-circulation well cleanup, be convenient to accident treatment, simple in structure, easy operating.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Five, the specific embodiment:

In conjunction with the accompanying drawings, the utility model will be further described:

Its technical scheme is: comprise drift size gauge tool main body 1, one end is provided with tubing thread 4, in the bottom of the other end of drift size gauge tool main body 1 sawtooth 2 is set, wherein, the inwall of 10-30 centimetre drift size gauge tool main body 1 is provided with the barb 3 of a plurality of triangles in the distance bottom, and barb 3 slopes inwardly.Described barb 3 is three isosceles triangles, be evenly distributed on the inwall of drift size gauge tool main body 1, and the inwall of the drift angle of isosceles triangle and drift size gauge tool main body 1 is 30 degree angles.

Foreign material around the sawtooth 2 of the bottom of drift size gauge tool main body 1 can be used for clearing up top of fish, simple in structure, the easy operating of the utility model, it both can keep original common drift size gauge tool function, can also be used under the prerequisite that the sand post is lower than 50-100cm, and the sand washing well operations recoils; It utilizes the hard sawtooth 2 of bottommost can adopt the mode of transferring tubing string while rotating to overlap to mill the sand washing construction, both saved the activity duration, improved operating efficiency again, effectively alleviated the labour intensity of operating worker, simultaneously, avoided tubing string because of repeatedly removing the wearing and tearing that screw thread is caused.

During use, meet card as the drifting tubing string, can anti-circulation well cleanup, be convenient to accident treatment, during anti-flushing well, utilize the barb of inwall to pull in the pit shaft in the past foreign material such as the left rubber of operation out.
