摘　　要：通过对当前国内外剩余油研究方法、模式的调研,结合中国东部老油田勘探开发的实际和复杂断块油气藏的特殊背景,采用了“油藏数值模拟法、水驱曲线法和产量递减法三结合”的剩余油研究思路,突出油藏的静动态结合,分析剩余油的形成和分布规律。并将次模式应用于S23断块东部单元沙二下一砂组剩余油分布规律研究,通过分析表明该方法实用,效果较好,这对于加深对剩余油分布新认识,为油田挖潜治理和合理开发奠定了坚实基础。According to the investigation and research on the ways and models of remaining oil in the domestic and international,the thinking is presented in the paper that the three ways:type A water drive curve,the reservoir numerical modeling,and the rule of the output decline are combined under the special background of complex fault block reservoir and the exploration and development of the old oil field in east china.And at the same time,the new thinking for the research on remaining oil calculations has put emphasis on the combination of static and dynamic reservoir.Meanwhile,it also validates the results of distribution regularity and reasons for the remaining oil of one sand set of S23 fault block.It indicates that the new way is effective,and according to the comparison among the three methods,the type A water drive curve and the reservoir numerical modeling have more useful results than the method of rule of the output decline.So the way for the three methods' combination provides the solid basis for the deepen new understanding for the distribution of remaining oil and increases of outputs of oil and gas in the oil field.
