摘要
针对双重介质油藏物模试验技术的复杂、特殊性,进行了双重介质物模的制备、相似准数的选择及三维岩块渗吸、周期注水试验等一系列物模基础试验技术的研制攻关,并对辽河油区各类岩性双重介质油藏的渗流特征进行了系统的整理归纳分析,初步确定了渗流特性指标,为双重介质油藏改善开发效果方式的确立提供了重要的试验基础参数。
The experiment technique of physical modeling for dual-media reservoir is sophisticated and special. A series of basic experiment techniques of physical modeling has been developed, including preparation of dual-media physical model, selection of scaling coefficient, 3D rock imbibition, and cyclic water injection test. Percolation characteristics of dual-media reservoirs with various lithologies in Liaohe oil province are systematically sorted and analyzed, and tentative percolation index has been determined, thus providing important basic experiment parameters for improving development effect of dual-media reservoirs.
