濮城油田东区沙二上1油藏东部、北部被边水圈闭,西部、南部为岩性尖灭,属于构造-岩性油气藏,沉积主体主要为来自东北部无缘的末端扇沉积,含油砂体主体以末端扇的分流河道砂体和近水道漫溢砂体沉积为主。油藏内部构造复杂,含油区域多受断层封闭,但为一套油水系统。经过长期的注水开发,油藏内部油、水分布变得异常复杂,控制和影响剩余油分布的因素较多,应用油藏数值模拟技术,结合测井、沉积相等因素进行分析,确定了该油藏的剩余油分布规律和控制因素,指出了油藏调整挖潜的区域。
The eastern and northern parts of the Es2 reservoir in the eastern part of Pucheng Oilfield are trapped by marginal water in the eastern part and the northern part of the reservoir. The western part and the southern part of the reservoir are lithologic extinction, belonging to the tectonic-lithologic reservoirs. The sedimentary bodies mainly consist of terminal fan with no margin from the northeast, The main body of the sandbody is mainly the distributary channel sandbody of the end fan and the diffusive sandbody sediment of the near channel. The internal structure of the reservoir is complex, and the oil-bearing area is mostly closed by the fault but is an oil-water system. After long-term waterflood development, the distribution of oil and water inside the reservoir becomes extremely complicated. There are many factors that control and influence the distribution of remaining oil. By using reservoir numerical simulation technology, combining logging and sedimentary factors, the oil The remaining oil distribution and control factors of the reservoir indicate the area where the reservoir is adjusted and the latent potential is adjusted.
