利用泥岩或页岩流体孔隙度的变化来预测地层孔隙压力的方法很多。本文重点叙述文留油田用声波测井法预测地层孔隙压力,采用试采法和等效深度法计算地层压力,并例举实例说明这两种方法的效果以及使用中应注意的问题。
There are many ways to predict the formation pore pressure using changes in the fluid porosity of shale or shale. This paper focuses on the prediction of formation pore pressure by acoustic logging in Wenliu Oilfield. The formation pressure is calculated by trial mining method and equivalent depth method. An example is given to illustrate the effectiveness of these two methods and the problems to be noticed in their use.
