采用优化反演法,并且综合了当前广泛采取的钻进基本方程,通过对钻时录井资料以及钻头磨损程度的情况进行分析处理。得到钻进方程中的各项数据系数,以此研发以系数反演法就计出的优化计算系统。通过对油田的各项系数进行计算和优化,得到了与实际结果基本吻合的钻进过程的累计进尺和钻进时间的预测数据。 Adopting the optimization inversion method and integrating the drilling basic equations which are widely adopted at present, the logging data and the degree of bit wear are analyzed and processed. The data coefficients in the drilling equation are obtained, so as to develop the optimization calculation system which is calculated by the coefficient inversion method. By calculating and optimizing the coefficients of the oilfield, the accumulated footage and drilling time prediction data are obtained which are basically in accordance with the actual results.
