Abstract：In viewofthe difficulty in force analysis of tools in casing sidetracking processof oil wells and the lack of casing sidetracking software in China，a dynamic model of milling tools and flexible subs was established，and the development of casing sidetracking-aided software with core technical modules was developed based on finite element theory.This software featured a casing sidetracking tool structure design， analysis ofthe hydraulic parameters of the whipstock’sseting， mechanical analysis and safety evaluation，as wellas visualization ofthe casing sidetracking process.By combining the force simulationresults of the casing sidetracking tool of a certain well in the Bohai Oilfield with theon-site operation data， the accuracy of the software simulation was verified.When the footage is about 2.65 meters，the cuting force and torque are relativelysmallAtthis point，alow rate ofpenetration（ROP）anda high weighton bit （WOB）should be adopted to enable the shoe to quickly passthrough the dead point position and ensure that the ROP during the casing sidetracking process is relatively stable，and thewindow length is suficient.This software provided a theoretical basis for the casing sidetracking process and has certain guiding significance for the parameter controlin on-site construction.

Key words：casing sidetracking; dynamic model; software development; mechanical analysis
