Aiming at the problem of erosion and wear of fluid parts of drilling equipment during oilfield development, on the basis of summarizing the existing erosion theories, five typical erosion wear theories including micro-cutting wear theory, deformation wear theory, extrusion forging theory, adiabatic shear theory and secondary erosion theory were systematically expounded. The main research methods of erosion wear and the research status at domestic and abroad were summarized and analyzed. The latest research results of erosion wear test device and numerical simulation was introduced in detail. The problems and research directions of the current research on erosion and wear of drilling and production equipment was pointed out. Theoretical reference was provided for research on erosion and wear protection of drilling and production equipment.
