Mechanical Analysis and Parameter Optimization Design of Sleeve Milling Operation String
This article presents an analysis of the mechanism of casing damage caused by casing grinding and milling operations,with a focus on the dimensions of wellbore conditions,the structure of the operation string,the performance of well repair fluids,and the construction parameters of the casing grinding and milling process.Additionally,a design method for casing grinding and milling operations has been established,and a software program has been developed for the mechanical analysis and parameter optimization design of casing grinding and milling operations.The software was employed to facilitate the calculation of wellbore trajectories,casing mechanics analysis,torque and tension calculations,casing grinding and milling tool combination optimization design,and construction hydraulic parameter optimization.The practical application of the software demonstrates its ability to calculate the load of the wellhead hook,the torque at the position of the casing milling cylinder,the torque of the overall casing milling pipe column,the dynamic wear resistance of the pipe column along the depth of the well,strength verification,and safety analysis.The error between the calculated results and the actual test results is within 5.5%.
