Description

Technical Field

[0001] The invention relates to the technical field of experimental research on erosion and wear of oil and gas field pipes, in particular to a high-temperature and high-pressure dynamic simulation erosion test system. Background Art

[0002] The erosion and wear of gathering and transportation pipes is a surface damage phenomenon caused by the fluid carrying solid particles flowing through the pipe surface. The factors affecting this phenomenon mainly include the metal properties of the pipe itself, such as hardness, ductility, etc.; the viscosity of the fluid and the shape, size, hardness, speed and angle of impact on the metal surface of the solid particles it carries. In addition, studies have shown that the ambient temperature and pH are also important influencing factors.

[0003] More than 70% of oil and gas wells in the western part of the South China Sea have sand production to varying degrees, and the current mechanical sand control methods can only prevent large particles from entering the wellbore. Erosion and wear are still one of the main forms of equipment failure. Various types of downhole tool adapters, elbows, Christmas trees, nozzles, and surface manifolds have many failures caused by erosion and wear. High-speed fluids carrying solid particles will cause a significant decrease in the equipment's carrying capacity, and even worse, it will cause perforation of the pipe wall, causing serious safety hazards in production.

[0004] The erosion and wear of various metal materials of petroleum machinery in oil and gas fields is a complex behavior involving many influencing factors. Due to the nature of the metal materials themselves, it is difficult to come up with a universally applicable theory. Therefore, there is an urgent need for an erosion test system with complete functions that can highly simulate the actual erosion conditions on site, so as to enhance researchers' deeper understanding of erosion and wear behavior through more refined experimental research.
