Description

technical field [0001] The invention relates to the technical field of oil and gas resource development, in particular to an erosion wear test equipment. Background technique [0002] Erosion wear refers to a kind of wear phenomenon in which the surface of the material is damaged when it is impacted by small and loose flowing particles. Its definition can be described as the loss of surface material when the solid surface is in contact with the fluid containing solid particles for relative motion. The fluid carrying the solids can be a high-velocity gas stream (known as sandblasting-type erosion) or a liquid flow (known as mud-type erosion). Erosion wear is a common form of wear in modern industrial production, and it is one of the important reasons for equipment and its parts to be damaged and scrapped. [0003] A large number of multiphase flow conditions are involved in the whole process of oil and gas field exploration and development. The erosion failure of tools and e...

AI Technical Summary

Problems solved by technology

[0004] However, the current research on material erosion mostly focuses on a single fluid erosion condition, that is, the multiphase fluid is impacted on the test piece at a certain speed and angle through the nozzle to complete the erosion of the test piece, which cannot be used for fracturing. Simulate the complex working conditions of pipeline material erosion failure in construction, reverse flow, well killing and blowout, high-pressure gas well sand production, etc., and obtain reasonable and effective experimental data to guide on-site safety production
