Embodiment 1

[0016] see figure 1 , the tool is cleaned in the oil pipe, and the cleaning knife includes three parts from left to right: a cutter body section 3, a grinding section 6 and a brush section 7, and a multi-ring ring-shaped scraper 2 is arranged on the outer peripheral surface of the cutter body section 3. A layer of polishing layer 5 is provided on the outer peripheral surface of the grinding section 6 , the outer surface of the brush section 7 is covered with a steel wire brush 8 , and the right end of the brush section 7 is also provided with an internal thread interface 9 .

[0017] When this embodiment is in use, the cutter body section 3 first extends into the oil pipe, and the internal thread interface 9 at the end of the brush section 7 is connected to the rotating device to drive the entire cleaning knife to rotate and push the cleaning knife into the oil pipe, and the cutter body section 3 is rotating When the scraper 2 on the surface scrapes and cuts the dirt on the in...

Embodiment 2

[0019] This embodiment is optimized as follows on the basis of Embodiment 1: the interior of the cutter body section 3, the grinding section 6 and the brush section 7 are all provided with connected water holes 4, and the front part of the cutter body section 3 , the middle part and the middle part of the brush section 7 are all provided with a water outlet hole 1 communicating with the water hole 4 and the external space.

[0020] The water hole 4 of this embodiment is used to pass through the decontaminated sewage, and the decontaminated sewage can moisten and soak the dirt on the inner wall of the pipe through the water outlet 1, which can increase the cleaning effect, make the cleaning more complete, and reduce the damage of the structure at the same time. The service life is extended, and the water outlet hole 1 is located at the front and middle of the cutter body section 3 and the middle of the brush section 7 so that the decontaminated sewage can be fully mixed with the...

Embodiment 3

[0023] This embodiment is further optimized on the basis of any of the above embodiments, specifically: the grinding layer 5 is a WC cemented carbide layer.

[0024] In this embodiment, WC cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, so the grinding layer 5 adopts Made of WC cemented carbide not only can meet the working requirements of the downhole, but also has strong wear resistance, which greatly prolongs the service life of the grinding layer 5 .

[0025] Preferably, the thickness of the grinding layer 5 is 8-12 mm. While prolonging the service life of the grinding layer 5, the waste of materials is reduced, so the thickness of the grinding layer 5 is 8-12 mm, which can not only ensure the normal use of the grinding layer 5, but also reduce the waste of materials.

Abstract

The invention discloses an inner-oil-tube cleaning tool. The inner-oil-tube cleaning tool sequentially comprises a tool body section (3), a polishing section (6) and a hairbrush section (7) from left to right, a plurality of annular scrapers (2) are arranged on the circumference face of the outer side of the tool body section (3), a polishing layer (5) is arranged on the circumference face of the outer side of the polishing section (6), the outer lateral side of the hairbrush section (7) is covered with a steel wire hairbrush (8), and an inner thread connector (9) is further arranged on the end portion of the right side of the hairbrush section (7). The inner-oil-tube cleaning tool in the design is complete and thorough in cleaning, low in cost and long in service life, and brings convenience to cleaning.

Description

[0001] technical field [0002] The invention relates to the field of oil pipeline cleaning, in particular to a cleaning tool for cleaning stains in oil pipelines. Background technique [0003] With the continuous development of the petroleum industry, the large number of sewage injection wells in various oil fields has increased the demand for various oil pipelines and water pipelines. After long-term use of oil and water pipelines, there will be many oil stains and dirt on the inner wall of the oil pipelines. Impurities, when the oil and water pipes are used for dynamic monitoring work such as oil well testing and pressure measurement, and when oilfield water injection is relatively clogged, it will affect the monitoring results and bring difficulties to water injection. Inconvenient; nowadays, when cleaning the oil pipe, a weighted rod or some cleaning tools are often used to clean the inner wall of the pipe, but either it is troublesome to clean, or the cleaning effect i...
