摘要
沈 8 4块是指静安堡复式油气聚集带中段、沈 84-安 12断裂背斜构造北部的沙三油气富集断块。为了研究该油田进入高含水开发阶段影响剩余油分布的主要因素 ,从油田地质、测井及实际生产情况入手 ,通过实例分析得出构造、储层非均质性及增产措施是影响该区块剩余油分布的主要因素 ,并认为构造及微构造高部位、封闭性断层附近、纵向上非均质性强的部位和平面上物性较差的区域是剩余油分布的有利区域 ,而且如果合理使用增产措施 ,会使剩余油富集在易于开采的区域。
Block Shen 84 is an oil gas accumulation fault block in Shasan formation located in the middle of Jing an bao oil gas pay zone and north area of Shen 84 An 12 anticline.Since the first production in 1984,this oil field has produced oil up to more than 3.5 million tons and its water cut has reached 55% by July,1998,i.e.,it has entered into high water cut stage.This paper analyzes the influence on remaining oil distribution of the block structure,reservoir heterogeneity in the block and stimulation treatment,and also gives a few application examples.From above analysis,the possible remaining oil distribution areas are deduced.
