采用仿真方法进行PDC钻头切削参数的量化是钻头个性化设计的重要技术手段。为提高PDC钻头钻进仿真的效率及精度，并与钻头三维设计系统实现无缝连接，在PDC钻头切削参数理论及切削量计算方法的基础上，利用UG软件的布尔运算功能进行了二次开发，基于UG/OPEN快速获取切削量的原理建立了 PDC钻头井底模型，将钻头的切削过程等效为几何结构的布尔减运算，通过数值运算获取切削体积、接触面积、切削力等参数。研究结果表明，切削参数仿真结果与既有数值方法仿真结果的变化趋势相同，并且具有更高的精度和仿真效率。基于UG/OPEN的PDC钻头切削参数仿真方法为切削参数获取提供了一种新的方法，可以为个性化PDC钻头的快速设计提供参考。

T he quantification of PDC bit cutting parameters using simulation method is an important technique for drill bit customization .To improve the efficiency and accuracy of PDC bit drilling simulation and realize a seamless connection with 3D design system of drill bit ,UG/OPEN was imported in the study . Based on PDC bit cutting parameters theory and original computing method of cutting volume ,the Boolean operation of UG software was used for redevelopment .Meanwhile ,the principle of UG/OPEN quick access to the cutting volume was utilized to build the bottomhole PDC bit model ,In this way ,the cutting process was simulated equivalent to the geometric Boolean subtraction ,and numerical computation was made to ob-tain cutting volume ,contact area ,cutting force and other parameters .The study showed that the simulation of cutting parameters revealed the same tendency as the existing numerical simulation ,and has higher accu-racy and simulation efficiency .Therefore ,the new method of cutting parameters simulation based on UG/OPEN provided a technical foundation for rapid customization of PDC bit .
