摘　　要：在注水开发中后期,储层单砂体相互之间连通关系和剩余油三维空间展布特征是研究的重点。扶余油田西5-8区块在经历溶解气驱、注水开发和3次大规模加密调整后,单砂体剩余油分布复杂,加大了后期有效注水开发的难度。按照单砂体划分原则和方法,采用单砂体精细刻画划分后,根据单砂体平面及剖面展布特征,分析研究井点剩余油控制因素、平面剩余油控制因素和纵向剩余油控制因素,得到主力砂体的水洗厚度变化情况从而知道各单砂体剩余油分布。During the mid-late stage of water flooding in reservoirs,the study is mainly focused on the communication between the single sand bodies and the 3D distribution of the remaining oil. After solution gas driving,water flooding and three large-scale infill well adjustments at Block West 5-8 of Fuyu oil field,the distribution of remaining oil in single sand bodies has become complex, increasing the difficulty of later water flooding. After fine description and division of single sand bodies by following the division principles and methods for them,the planar and sectional features of sand bodies are studied,the controlling factors for the remaining oil at the well point,or in the horizontal and vertical planes are analyzed. Then the variation in the thickness of the main sand bodies already flushed by water can be obtained to know distribution of the remaining oil.
