摘　　要：针对八区克上组油藏S4+5层长期注水不满足,地层压力持续下降,加之油水井井况变差,井网不完善,全区产量不断下降,油藏急需进行调整。2008年进行精细油藏描述,采用多种技术方法,定量描述油藏剩余油分布,研究剩余油分布规律。平面上,剩余油集中分布在克乌断裂附近、井网不完善且有效厚度较大的部位;纵向上,剩余可采储量主要集中在S51、S52-2、S41-1、S42-2层。根据剩余油研究,部署控制井及试验井组符合率高,为油藏整体二次开发,提高油藏采收率,提供了依据。According to the situation that the eight grams of the reservoir in Area S4+5 layer does not meet the long-term injection and reservoir pressure keeps declining,combined with the deterioration of the oil wells condition,the imperfect patterns and the region declining production,the reservoir needs to be adjusted.With detailed reservoir characterization for 2008 and a variety of technical methods,the distribution of the remaining oil is described quantificationally and distribution rules of remaining oil is researched.On plane,the remaining oil concentrated near the fault in Ciu,and where patterns are imperfect with a large part of effective thickness;Vertically,the remaining recoverable reserves mainly concentrated in the S51,S52-2,S41-1,S42-2 layer.According to the research of residual oil,deployment control group wells and test wells are highly consistenty with each other,which provides the basis for the secondary development of the whole reservoir and higher oil recovery rate.
