| 摘 要： | 非均质性是油气藏的基本特性,也是影响油气面采收率的重要因素.它是反映油气藏的渗透率、孔隙度、有效厚度及其连通性的综合特征参数.不同油气藏在投入开发后,其产量随时间变化的分布曲线与油气藏自身的非质均性有密切关系.利用伽马分布描述油气藏产量随时间的变化,研制了典型曲线的理论图版,通过拟会求解,可判断油气藏的非均质程度.

| Abstract: | The heterogeneity is a basic characteristic of oil and gas reservoirs. At the same time,it is a complex characteristic factor including permeability, porosity, effective thickness and connectivity. For different oil and gas reservoirs,it is considered that the distribution curve between the production and time has intimate relation with its heterogeneity. Authors describe the relationship of the production versus the time by gamma distribution,and develops the theoretical plate of typical curves,which can be applied to determine the degree of the heterogeneity of oil and gas reservoirs,using matching solution technique. |
