[0002] During oil and gas drilling and production, the oil pipe and casing are used underground for a long time, and the inner wall of the casing will rust and slightly deform, and the inner wall of the oil pipe will corrode and condense wax. The occurrence of these two abnormal phenomena will greatly affect the normal oil and gas production operations. In serious cases, there will even be accidents of casing and oil pipe blockage, forcing the oil and gas drilling and production operations to be unable to proceed, causing great losses to the oil and gas production work.

[0003] At present, the common practice to deal with this phenomenon is to use casing inner wall cleaning tools (including scrapers, brushes, magnetic columns, etc.) to remove rust and wax deposits inside the oil casing. However, due to the wide variety and structure of such products on the market, there is no measurement equipment for the cleaning effect of each tool, which makes it impossible for oil field technicians to make judgments. The selection of products and the setting of usage parameters have been in the test and exploration stage, and it is impossible to accurately guide field operations. There is an urgent need for a scraper field simulation test equipment to simulate casing scraping tests on products of different manufacturers and types, determine product performance, obtain the best usage parameters, and ensure accurate and efficient field use.

[0004] For this simulation test equipment, our design idea is to design two major components, one of which is used to clamp, position and rotate the test cleaning product, and the other is used to drive the simulation sleeve that slides on the test cleaning product to move up and down to simulate the cleaning process. Because there was no related equipment in the industry to learn from before, how to design the two major components of the simulation test equipment has become a technical problem that needs to be solved urgently.

[0018] The movable support part 2 includes a support shaft 8 vertically fixed on the base 4, a rack 9 is arranged on the inner side wall of the support shaft 8 along its height direction, the rack 9 is meshed with a gear 10, the gear 10 is installed in the installation cavity of the limiting top rack 11, the limiting top rack 11 is movably sleeved with the support shaft 8 and extends in the horizontal direction, and a movable limiting top rack 12 is arranged at the bottom of one end of the limiting top rack 11 away from the support shaft 8. Since the gear 10 is meshed with the rack 9, when the gear 10 rotates, the gear 10 can move up and down along the rack 9, thereby driving the limiting top rack 11 to move up and down to adapt to the test cleaning products 3 of different heights, and the movable limiting top rack 12 on the limiting top rack 11 is pressed against the head end of the test cleaning product 3, thereby realizing the limiting fixation of the test cleaning product 3.
