以阵列全波列声波测井资料为主，结合常规测井、高分辨率地层倾角测井资料以及RFT地层压力测井资料对地层岩石综合力学机械特性进行了深入的分析。在正确、合理地处理资料并计算数据的基础上，重点讨论了岩石破裂压力在井眼稳定性分析中的作用。特别是钻井过程中钻井液比重的确定。利用数理统计的方法得到了区域性声波阻抗与横渡时差的经验公式，对于没有进行全波列声波测井的井也可以由该公式计算出横波时差，从而进一步求出岩石弹性力学参数。利用岩石自然破裂压力系数在裂缝发育段预测合理钻井液比重取得良好的效果。
Based on the array full-wave acoustic logging data, combined with conventional well logging, high-resolution dip logging data and RFT formation pressure logging data, the synthetic mechanical properties of the strata are analyzed in depth. On the basis of correctly and reasonably processing data and calculating the data, the role of rock burst pressure in wellbore stability analysis is mainly discussed. In particular, the determination of the proportion of drilling fluid during drilling. The empirical formula of regional acoustic impedance and transit time difference is obtained by using mathematical statistics method. For the wells without full-wave acoustic logging, the time-difference of transverse wave can be calculated by this formula, and further the rock mechanics parameters can be obtained. The natural rupture pressure coefficient of rock was used to predict the specific gravity of drilling fluid in the fracture development well.
