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 seepage mechanics considers reservoirs to be homogeneous, however, most of the actual fractured reservoirs are in heterogeneous formations. Therefore, considering the influence of stress sensitivity and starting pressure gradient, the seepage law of fractured reservoirs is studied, and the finite conductivity vertical fracture model of deformed triple reservoir is established. Corresponding model curves are also discussed. The influence of each parameter on pressure is discussed.
