摘要
传统渗流力学考虑储层是均质的,但是,实际的裂缝性油藏大多处于非均质地层中。因此,考虑应力敏感和启动压力梯度的影响,研究裂缝性油藏渗流规律,建立变形三重介质油藏有限导流垂直裂缝模型,并作出相应的样板曲线,讨论了各个参数对压力的影响。
Traditional percolation mechanics considering reservoir is homogeneous,however,the actual fractured reservoir is mostly inhomogeneous formation.In this paper,considering the stress sensitivity and the influence of the start-up pressure gradient,the seepage rule of the fractured reservoir was studied,a limited diversion vertical cracks model of deformation triple medium reservoir was established,corresponding template curves were gained,and the influence of various parameters on the stress was discussed.
