To investigate the influence of rotational speed and drilling pressure on the milling efficiency of flat-bottomed milling shoes, a three-dimensional milling model of flat-bottomed milling shoes and deformed casing was established by using ABAQUS finite element software, and the optimal parameter combinations of milling efficiency were investigated at rotational speeds of 70~90r/min and drilling pressures of 5~25kN. The results show that: with the increase of drilling pressure and rotational speed, the mass loss of casing and the amount of footage of the grinding shoe increase, and the grinding and milling efficiency is optimal under the process parameters of rotational speed of 90r/min and drilling pressure of 15kN. This paper provides an analytical method for the subsequent optimization and improvement of the evaluation of the pipe repair process and promotes the technological development of the research on the casing change mechanism and prevention and control countermeasures in shale gas wells.
