| 摘 要： | 四川盆地大多数气藏属于裂缝孔隙型气藏,气藏非均质性强.经典的径向均质复合试井解释模型与气藏实际情况不相符,解释结果与实际地质情况出现抵触现象.针对这种情况,建立了多区双重孔隙介质复合地层模型,求得了该模型的拉氏空间解,分析了其典型的压力动态特征,并对影响因素可能对曲线产生的影响进行了分析.

| Abstract: | Many gas reservoirs in Sichuan basin belong to crack porosity one,of which non-uniform is much high.Classical radial uniform com- pound interpreting model is not match with actual situation of gas reservoir that makes the results colliding to actual geology condi- tions.According to those cases,percolation mathematic model in compound gas reservoir with dual medium of many sections has been established to acquire Laplace space solution,analyze its typical pressure dynamic property,and construe the influence of other influ- ence factors to pressure curves. |

| Keywords: | excessive section dual medium radial compound mathematic model Laplace transform typical curve dynamic performance |
