[0002] In oilfield production, oilfield pipeline transportation involves various fields. Due to the characteristics of internal sealing of the pipeline, many attached oil residues and other substances will be produced inside the oilfield pipeline after long-term use, which will cause the internal space of the oilfield pipeline to narrow, thereby affecting the efficiency of internal oil transportation. In severe cases, the pipeline may be blocked. Therefore, it is necessary to clean the inside of the oilfield casing from time to time.

[0003] The applicant has found that the existing oilfield casing generally uses a scraper or high-pressure impact method to clean the oil residue and other substances inside the oilfield casing during internal cleaning. However, the scraper or high-pressure impact method is easy to damage the casing wall and reduce the service life of the casing. Secondly, it is not conducive to efficient cleaning of the oil residue and other substances remaining on the inner wall of the oilfield casing, which is not conducive to use. Therefore, an oilfield casing cleaning anti-blocking structure is proposed to solve the above-mentioned problems. Utility Model Content

The many technical effects (A, B, C) that can be produced by the preferred technical solution among the many technical solutions provided by the utility model are described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: preferably, the oilfield casing cleaning and anti-blocking structure provided by the utility model comprises a water-gas transmission sleeve, the top of which is respectively connected with a high-pressure water pipe and a high-pressure air pipe, the bottom of which is rotatably connected with a rotating assembly, the bottom of which is fixedly connected with a cone column, the outer side of which is fixedly connected with an anti-blocking spiral blade, and a rotating wiping assembly is arranged on the outer side of the rotating assembly;

[0006] The rotating assembly includes a rotating sleeve, a guide plate and a nozzle. The rotating sleeve is rotatably connected to the bottom of the outer side of the water-gas transmission sleeve. The bottom of the rotating sleeve is fixedly connected to the top of the cone column and is connected. The guide plate is respectively connected to three circles of the outer side of the rotating sleeve, and the nozzle is opened on the outer side of the guide plate.

[0007] Preferably, the rotary wiping assembly comprises a support rod and a wire brush, wherein the support rod is fixedly connected to three circles of the outer side of the rotary sleeve, and the wire brush is fixedly connected to the outer side of the support rod;

[0008] Preferably, a pressure-assisting hole is opened on the outer side of the cone column, and the pressure-assisting hole is located on the inner side of the anti-clogging spiral blade;

[0009] Preferably, a cone needle is fixedly connected to the bottom of the cone column, and the cone needle is located at the bottom of the anti-clogging spiral blade;

The two can also be passed at the same time for coordinated use, and then the high-pressure water or high-pressure air entering the water-gas transmission sleeve quickly surges into the guide plate outside the rotating sleeve, and then because its guide plate is in an arc-shaped curved shape, the high-pressure water or high-pressure air entering the guide plate is sprayed outward to the inner wall of the oilfield casing through the nozzle opened on the outside of the guide plate. , so that after being ejected at high speed through the nozzle, a reverse impulse is generated, which prompts the guide plate to drive the sleeve to rotate clockwise at high speed on the outside of its water and gas transmission sleeve, so that the high-pressure water or high-pressure gas ejected from the nozzle at high speed washes away the oil residues and other substances on the inner wall of the oil field casing. At the same time, the rotation of the guide plate drives the cone column and the anti-clogging spiral blades at the bottom of the sleeve to rotate and push into the inside of the oil field casing, so as to decompose the oil residues blocked in the oil field casing, and further enhance the flushing and cleaning of the oil residues by the nozzle, and at the same time, the wiping assembly located on the outside of the sleeve rotates at high speed and generates friction with the inner wall of the oil field casing, thereby further washing away the oil residues and other stains attached to the inner wall of the oil field casing, and the overall coordination can achieve the effect of efficiently cleaning the oil field casing, and reduce the degree of damage to the inside of the oil field casing, so as to facilitate use.
