Description

technical field [0001] The invention belongs to the field of oil and gas drilling devices, and in particular relates to an erosion test device. Background technique [0002] The internal blowout prevention tool belongs to the fast blowout prevention tool in the well control equipment, which can effectively control the occurrence of blowout and kick accidents during drilling. It is an important safety equipment in the field of oil and gas drilling. During the drilling process, the erosive wear of drilling mud mixed with cuttings and other solids on the internal blowout preventer tool is one of the main failure modes. The simulated erosion test model based on the erosion theory is an important means to study its erosion failure. The design optimization and process improvement of the product are carried out through the obtained experimental data, and its service life in the erosion and wear environment in various working conditions is verified. The existing erosion test devi...
