摘　　要：结合目前广泛采用的钻进基本方程,对钻时录井资料、钻头磨损资料进行处理,运用优化反演法求取钻进方程中的各项系数,开发出基于系数反演法的钻井参数优化计算系统。应用该计算系统对河南油田南88井的钻进参数和水力参数进行了优化计算,进而对钻进过程的累计进尺和钻进时间进行了预测,计算结果与实际钻井数据基本符合。The data of drilling time log and drill bit wearing were processed in combination with basic drilling equations which were widely used.The optimized inverse methods were deployed to derive parameters in well drilling,a system for optimizing drilling parameters based on coefficient inversion was developed.The system is used for optimally calculating the drilling and hydraulic parameters of Well Nan 88 in Henan Oilfield,consequently the accumulated rate of penetration and drilling time are predicted.The result is consistent with actual drilling data.
