本文目的是调查具有不规则特征的天然裂缝油藏的不稳定压力动态。本研究建立在以往研究成果的基础上 ,这些研究表明一些油藏的裂缝网络具有不规则的参数。因此 ,根据这个假设 ,在拉普拉斯区间导出了双重孔隙系统的近似的解析解。将这个解与有限元的解进行了对比 ,得到了一致的结果。给出了一个拟稳定流动状态的解析解 ,并举例论证了分析单井的拟稳定状态流动压力和不稳定压力数据的重要性。以便充分表征具有不规则几何形状的天然裂缝油藏 The purpose of this paper is to investigate the unsteady pressure dynamics of natural fractured reservoirs with irregular characteristics. This study is based on previous research that shows that some fractures in the reservoir have irregular parameters. Therefore, based on this assumption, an approximate analytic solution of the double porosity system is derived in the Laplace interval. Comparing this solution with the solution of the finite element method, we get the same result. An analytic solution of the quasi-steady flow state is given and an example is given to demonstrate the importance of analyzing quasi-steady flow pressure and unsteady pressure data of a single well. In order to fully characterize natural fractured reservoirs with irregular geometries
