研究鄂尔多斯盆地镇泾油田长8油层组储集层沉积相、成岩相和孔隙结构, 利用岩心、薄片、钻井和测井等资料, 分析长8油层组储集层岩石物理相, 对储集层相对渗透率进行分类评价. 按照沉积相、成岩相和孔隙结构, 归纳总结出4类岩石物理相. 基于岩石物理相分类, 优选prison水相相对渗透率模型和普适公式油相相对渗透率模型, 分别作为研究区水相、油相相对渗透率的计算模型. 结果表明, 基于岩石物理相分类计算的油、水相对渗透率完全满足评价储集层的产液情况, 从而进行研究区长8 储层的油、水层的划分.

The sedimentary facies, diagenetic facies and pore structures of the Upper Triassic Yanchang Formation Member 8 (Chang 8) reservoir in the Zhenjing region are studied by using core observation, thin section analysis, well logging and drilling data. The petrophysical faices of Chang 8 oil layers are analyzed to evaluate and classify the relative permeability. The petrophysical facies are classified into four types according to sedimentary facies, diagenetic facies and pore structure. The prison model of water relative permeability and universal formula of oil relative permeability are chosen to calculate water relative permeability and oil relative permeability, respectively. The results show that the calculated oil and water relative permeability based on the classification of petrophysical facies can be used to fully match with the production data, which verifies the accuracy of the proposed method to be used to evaluate the oil and water layers of Chang 8 reservoir.
