基于Buckley-Leverett油水两相非活塞驱替理论、原苏联油藏专家ЭΦPCD艾富罗斯)的实验理论及中国已故院士童宪章的计算储量的经验公式,结合现场生产资料和油藏流体的物性参数,推导出求取油藏原始含油饱和度和目前油藏含油饱和度的一种新方法。利用介绍的方法求取L油藏原始含油饱和度和目前含油饱和度,并将结果与实验方法进行了对比,其误差仅为1.45%。

Based on the theory of Buckley-Leverett of the oil being displaced by water in non-slug flooding and the laboratory test of an expert in oil field development named ЭФPCO of former USSR and the empirical formula of caculating reserves of Tong Xianzhang who was an academician of the Chinese-Academy of Engineering. Combining the production data with reservoir fluid data and its parameters, this paper deduced a new method to get the initial oil saturation and current oil saturation in a reservoir. Using the method of the paper's introduction, we get initial oil saturation and current oil saturation and compare initial oil saturation with experimental result, the error of calculation is less than 1.45%.
