Abstract

The utility model relates to a special tool for cleaning the oil pipe, which consists of a body, a cutter, a steel wire brusher and an adjusting screw. The body presents the 'PI' shape; inclined through-hole is opened on the pipe wall on the upper end of the body; the cutter is a taped leptospira with the diameter at the both ends over that in the middle; the cutter is jacketed on the external pipe wall of the body by the protection guard on the upper and lower end of the cutter; the steel wire brusher and the adjusting screw are arranged in turn below the protection guard; the adjusting screw can be used to adjust the diameter at the middle part of the cutter; the utility model can efficiently remove the inside dirty, wax and rust and so on, has an especially obvious cleaning effect to the oil pipe with deformation and diameter reduction, etc. and in the high temperature and corrosive environment.

Description

A kind of oil pipe cleans specific purpose tool

Technical field: the utility model relates to a kind of oil pipe and cleans specific purpose tool, belongs to oilfield oil well production technique field, is used in particular for the downhole tool technical field of drifting.

Background technology: at present, the on-the-spot oil pipe that uses cleans specific purpose tool in the oil field, by the centre is that hollow latus rectum bar, jack rabbit, wire brush constitutes, combination between latus rectum bar and the jack rabbit is installed as fixedly connected, and jack rabbit is the common thickened steel-tube that an external diameter is slightly less than pipe aperture, can not contact fully with tube inner wall, there is following defective in the on-the-spot use: can only play the effect that detects pipe aperture, if tube inner wall has incrustation scale, the cement residue, burrs etc. will bit freezing; If meet sand production or tubing deformation, undergauge etc., also can cause bit freezing, not only efficient is low, and personnel labor intensity is big, and has aggravated the wearing and tearing of oil pipe, and the operating cost height is long in time limit, influences oil well yield.

Summary of the invention: the purpose of this utility model is the drift size gauge tool function singleness that overcomes wash oil well tubing internal diameter in the background technology, meet the defective that sand production or tubing deformation, undergauge etc. cause bit freezing, and a kind of oil pipe that can effectively improve the job execution effect of design cleans specific purpose tool.

The utility model is made up of body, cutter, wire brush, adjusting nut, and body is " П " font structure, has oblique through hole in the top on the tube wall; Cutter is the reducing conveyor screw, and the two ends diameter is less than the middle part diameter, and the shielding cover by its upper/lower terminal is installed wire brush and adjusting nut successively under low protection cover on the outer tube wall of body.

The invention effect: the utility model can be effectively except that the dirt of removing tube interior, wax, corrosion etc., and particularly remarkable to high temperature, corrosive atmosphere and oil pipe cleaning performances such as tubing deformation, undergauge, the scope of application is wide, and installation, maintenance is convenient.

Accompanying drawing 1 is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model is described further:

By accompanying drawing 1 as can be known, the utility model is made up of body 3, cutter 6, wire brush 9, adjusting nut 10, and body 3 is " П " font structure, has oblique through hole 2 in the top on the tube wall; Cutter 6 is the reducing conveyor screw, and the two ends diameter is less than the middle part diameter, and the

protective cover

4,8 by its upper/lower terminal is enclosed within on the outer tube wall of body 3, at low protection cover wire brush 9 and adjusting nut 10 is installed successively for 8 times.

The utility model is put into the oil pipe 1 that needs cleaning, exterior power sprays into the High-Pressure Water that is added with cleaning fluid to oblique through hole 2 feedings of body 3, cutter 6 along with High-Pressure Water input and rotate and advance, rotary speed is adjusted by feed speed, when meeting tubing deformation, undergauge, slight bending, adjusting adjusting nut 10 moves axially the protective cover 8 of cutter 6, change cutter 6 middle part diameters, then scraping is carried out in dirt, wax, the corrosion of tube wall, afterbody wire brush 9 is scrubbed simultaneously, further to reach the purpose of thorough cleaning.

Claims

1, a kind of oil pipe cleans specific purpose tool, is made up of body (3), cutter (6), wire brush (9), adjusting nut (10), it is characterized in that body (3) for " П " font structure, has oblique through hole (2) in the top on the tube wall; Cutter (6) is the reducing conveyor screw, and the two ends diameter is less than the middle part diameter, and protective cover (4), (8) by its upper/lower terminal are enclosed within on the outer tube wall of body (3), and wire brush (9) and adjusting nut (10) are installed under low protection cover (8) successively.
