Research Progress and Prospect of Erosion and Wear of High Pressure Manifold in Hydraulic Fracturing Conditions

Abstract

In hydraulic fracturing construction, the inner wall of the high pressure manifold withstands the erosion and wear of high-velocity and high-strength proppants in the sand-carrying fluid, which can easily lead to damage and failure.By summarizing the existing erosion theory and erosion experimental device, the research results on the erosion and wear of high pressure manifold materials at home and abroad were systematically introduced.Then, the applicability of rotary, jet and pipe flow test devices to the erosion and wear of high pressure manifold under hydraulic fracturing conditions was compared and analyzed, and the influence law of test parameters on erosion rate of high pressure manifold in jet erosion and wear test was emphatically analyzed.Finally, the problems and future research directions in the research on erosion and wear of high pressure manifolds under current hydraulic fracturing conditions were pointed out.
