双河油田进入高含水后期开发以来,研究厚油层层内夹层分布规律,并对强水淹厚油层层内剩余油进行挖潜成为一种新的开发方向。针对双河油田高含水后期的主要特点,从夹层的成因和形成机理入手,通过双河油田438块厚油层层内细分对比研究,总结出438块各单层夹层分布规律,分析厚层内剩余油分布的特点及规律,提出如何寻找剩余油,进而如何挖掘剩余油,达到提高油田开发效果的目的。成果对油田高含水后期强水淹厚油层层内剩余油挖潜工作具有重要的指导作用。 Since the late development of Shuanghe Oilfield, the research on the distribution of sandwiches in thick oil reservoirs and the exploitation of remaining oil in the heavily flooded thick reservoirs have become a new development direction. According to the main features of the high water cut in the Shuanghe Oilfield and the formation and mechanism of the intercalation, 438 blocks of oil layers in Shuanghe Oilfield were subdivided and compared. The distribution of 438 single layers was summarized, The remaining oil distribution characteristics and rules, put forward how to find the remaining oil, and then how to tap the remaining oil, to achieve the purpose of improving the development effect of the oil field. The results have an important guiding role in the potential oil tapping of residual oil in the strong water-flooded reservoir in the late stage of high water cut in the oilfield.
