基于单砂体内部特征(岩性、物性、厚度及其分布等)控制着驱油效率与波及体积,且又受控于其沉积过程,根据单砂体成因、形成过程,确定了微相单砂体及其内部能量单元的沉积模式,进而实现单砂体内流动单元的划分.以杏南PⅠ4单元远砂坝微相为例,建立了远砂坝能量相单元沉积模式,在此控制下,将远砂坝划为4类流动单元6级能量单元,并将远砂坝内部能量相单元、形成机制、流动单元有机结合,揭示了远砂坝内部流动单元平面分布规律.
Based on the characteristics of single sand body (lithology, physical property, thickness and its distribution), the efficiency and volume of oil displacement are controlled and their deposition process is controlled. According to the formation and formation process of single sand body, Sand bodies and their internal energy units, and then to realize the division of the flow units in the single sand body. Taking the microfacies of the distal bar of the PⅠ4 unit in Xingnan as an example, the depositional model of energy facies unit of the distal bar is established. Under this control, The long-distance sand dam is divided into 6 types of energy units of 4 types of flow units, and the energy phase units, formation mechanisms and flow units inside the long-barrage are organically combined to reveal the plane distribution rules of the flow units inside the far-sand bar.
