摘要
本文通过井约束反演数据体提取层速度 ,建立精确速度场 ;从井出发 ,应用傅里叶趋势分析求取正常压实趋势层速度 ;经过衍生 Fillippone法计算压力系数 ;在压力系数数据体中分析目的层压力分布规律 ,研究压力异常与油气藏关系 ,结合构造、储层等资料预测油气有利分布区。实钻验证 ,本文压力预测结果与钻井数据吻合
Through taking interval velocity by well constrained inversion data body, the paper constituted accurate velocity for normal compaction trend by using Fourier trend analysis starting from well, analyzed the rule of pressure distributions in objective interval in data body of pressure coefficients after calculating pressure coefficients with derivative Fillippone method, studied the relation between pressure anomaly and oil gas reservoir and predicted the prospective area by combining with structure and reservoir data. The pressure prediction coincides with drilling results after drilling examination.
