Description

Technical Field

[0001] The utility model relates to the technical field of petroleum engineering, in particular to a device for cleaning the inner wall of a water injection pipe in a petroleum engineering project. Background Art

[0002] During the use of petroleum water injection pipes, scale, silt and other impurities will inevitably accumulate. If these impurities are not cleaned in time, they will pollute the water quality. The accumulation of impurities and sediments will cause the inner diameter of the pipe to shrink, the flow rate to decrease, and even cause pipe blockage. The sediment and impurities in the pipe will increase the friction loss of the fluid and reduce the transportation efficiency of the pipe. The accumulation of sediment and impurities will also cause corrosion and wear on the inner wall of the pipe, shortening the service life of the pipe. Cleaning work can timely discover and deal with safety hazards in the pipeline, prevent production accidents caused by pipeline blockage, leakage and other problems, and ensure production safety.

[0003] After searching, the Chinese patent announcement number is CN218361132U, which discloses a device for cleaning the inner wall of a petroleum engineering water injection pipe for circulating water, including: a collecting barrel, a movable shell and a water injection pipe, the bottom and top ends of the collecting barrel are both threadedly connected to a barrel cover, and a filter plate is fixed inside the collecting barrel, a dual-axis motor is fixed inside the movable shell, and the output end of the dual-axis motor is connected to a roller, an electric telescopic rod is installed in the middle of the movable shell, a servo motor is fixed inside the protective cover, and the output end of the servo motor is fixedly connected to a crushing roller, a cleaning rod is fixed on the outer side of the crushing roller, and a cleaning plate is fixed on the right side of the cleaning rod, and the water injection pipe is located on the outside of the movable shell.

[0004] The above patent can clean the inner wall of the water injection pipe and can adapt to water injection pipes of different diameters and depths. However, when adjusting the depth, the roller is likely to damage the inner wall of the water injection pipe, causing wear on the water injection pipe and reducing the service life of the water injection pipe.
