摘要
详细介绍了欠压实和流体膨胀这两类形成异常高压地层成因的 σ- V曲线的区别 ,提出了一套用卸载参数来分析异常压力形成原因的方法 ,并利用该方法在新疆两个油田上的两个构造进行了利用地震资料预测地层孔隙压力的研究 ,经实测资料验证 ,预测的结果较为理想。
The differences between undercompaction and fluid expansion which are two main reasons formed the σ- V curve of abnormal high pressure formation are introduced in detail and a set of methods using unloading factor to analyze the causes of abnormal pressure are also provided. By use of the methods to predict formation pore pressure of two structures in two certain oilfields in Xinjiang, the field test data show that the results of prediction are desirable.
