摘要
利用地震资料经处理提取地层层速度数据 ,然后进行地层孔隙压力的预测 ,在此基础上利用史蒂芬法进行地层破裂压力的预测 ,该方法在塔里木和吐哈油田的两个构造上使用 ,预测精度达 90 %以上 。
Formation velocity data are abstracted from seismic data, and the pore pressure is predicted according to petroleum industry standard, 'SY/T 5623 1997'. Based on this condition, formation fracture pressure can be predicted. This method has been used in two structures in Tarim and Tuha oilfields. Its precision is up to 90%, which can meet the requirement of engineering design.
