| 摘 要： | 在介绍具有连续基质颗粒大小分布和孔间表皮裂缝性油藏的不稳定压力分析模型的同时。提出了代表实际变化的裂缝密度和均匀性油藏的基质岩块大小分布概率密度函数，给出Laplace空间井筒压力解。该理论通过裂缝跨度变化拓宽了以前的双孔隙油藏模型，在不考虑孔间表皮的情况下，对非均匀裂缝性油藏压力动态进行了分析。

| Abstract: | The paper introduces the transient pressure analysis model for fractured oil reservoir with continuous matrix grains size distribution and skin between fractures. At the same time, fracture density, which indicates actual variation, and the probability density function of basement rock size distribution in homogeneous reservoir are presented and the solution of well-bore pressure is supplied in Laplace domain. Through the variation of fracture span, the theory improved the dual-porosity reservoir model. Pressure behavior is presenteded without skins between fractures in the heterogeneous fracture reservoir. |
