摘要
异常地层压力包括异常低地层压力和异常高地层压力,高异常压力是石油工作者主要研究对象。形成异常地层压力的原因主要有成岩作用、热力作用、生化作用、构造作用、渗析及流体密度差异作用等。异常地层压力的预测方法总结起来不外乎三大类:地球物理勘探方法、钻井资料分析法、地球物理测井方法,这三种方法都有本身的局限性。异常地层压力的研究对指导油田的勘探、开发和钻井工程都具有极其重要的意义。
Abnormal formation pressure includes ultra - low formation pressure and ultra - high formation pressure. High abnormal pressure is main studying objective for researchers. The reasons forming abnormal formation pressure mainly includes digenesis, thermogenesis, biochemical action, tectonic action, dialysis, and fluid density difference action. Predictions of abnormal formation pressure include three methods, geophysical prospecting, drilling data analysis, and geophysical logging. It is of significance for guiding exploration and development and drilling engineering of the oilfield to conduct the study on abnormal formation pressure.
