鄂尔多斯盆地某油区延10储层非均质性特征分析 摘要：储层非均质性研究是油气田勘探与开发地质研究中的重要基础工作, 影响地下油水的运动规律, 控制着剩余油的分布。本文针对储层的区域地质背景、沉积条件和特征,应用现代石油地质学、储层地质学、油层物理学、地球物理测井等理论为指导,分析储层小层的The analysis of Yan 10 reservoir heterogeneity in certain oilfield in Ordos basin Abstract：Study of reservoir heterogeneity is important basis in the study of oil and gas field exploration and development of geological work, sedimentary microfacies, fault, fluid properties and sandwich various geological factors such as comprehensive show reservoir heterogeneity within the reservoir, affect the movement of underground water, controlling the remaining oil distribution, the study of the exploration deployment and adjustment of oilfield injection-production well spacing, extract and improve recovery can provide scientific basis for effectively. Yan 10 reservoir in the study area, the author of this paper the regional geological background, sedimentary conditions and reservoir rock characteristics, application of modern petroleum geology, reservoir geology, reservoir physics, geophysical well logging theory as the instruction, from micro, layer, interlayer and plane in four aspects analysis Yan 10 reservoir heterogeneity characteristics of three small layers, it is concluded that the study area Yan 10 section of reservoir heterogeneity stronger as a whole.
