摘　　要：江苏油田整体属于复杂小断块油田,储集层平面展布形状对开发井网部署起着不可忽视的控制作用,一定程度上决定了储量的品位,现有油藏分类研究未能针对性地全面考虑。以复杂性科学研究为指导思想,提出了综合考虑储集层物性、分布形状及流体性质等因素,采用权重评判计算方法,构造了一种动静态结合、量化的油藏分类评价方法。该方法首次将储集层平面展布因素考虑到复杂小断块油藏分类评价中,结果表明,储集层平面展布不但对复杂小断块油气田油藏分类影响较大,而且提高了油藏分类对复杂小断块油藏开发的指导作用。Jiangsu oil field is characterized by reservoirs with several complex minor fault blocks. The arrangement of well patterns for development them is controlled by their configurations in plane distribution, which decide reserves quality in a certain extent. However, they have not been considered completely in current researches of reserves classification. The paper presents a comprehensive reservoir classification method that considers such development and geologic factors as reservoir physical property, distribution, fluid property and reservoir shape, using complexity scientific study and weight assessment. Among them the reservoir plane distribution as an important factor is considered into such a reservoir classification and evaluation in the first place. The results indicate that this factor is of an active effect on the reservoir classification and taken as a guidance for in-depth development of the complex minor fault block reservoirs.
