针对克拉玛依油田二中西八道湾组湿地扇相砾岩储层岩性粗和非均质强等特点,综合各种地质、测井、化验分析及开发动态资料,优选出影响流体渗流的6项特征参数,将砾岩储层划分为E,G,M,P等4种流动单元类型。根据储层岩性、物性及微观孔隙结构特征,对储层流动单元进行了分类评价。通过流动单元与剩余油饱和度平面图叠合分析,总结了不同流动单元剩余油的分布特点。E类流动单元储集渗流能力最好,平面上呈条带状分布,注入水易形成高渗通道,采出程度高,剩余油饱和度低;G类流动单元储集渗流能力次之,分布面积大,为中等—弱水淹,剩余油相对富集,是下一步挖潜的主要目标。
According to the characteristics of coarse and inhomogeneous fan-facies conglomerate reservoirs in the second Badaowan Formation of Karamay Oilfield, the six features that affect fluid seepage Parameters, the conglomerate reservoir is divided into E, G, M, P and other four kinds of flow cell types. Based on lithology, physical properties and microscopic pore structure characteristics of reservoirs, the flow units of reservoirs are classified and evaluated. Through the superposition analysis of the flow unit and the remaining oil saturation plan, the distribution characteristics of remaining oil in different flow units are summarized. Class E flow units have the best seepage capacity and strip distribution in the plane, which is easy to form high permeability channel with high water production rate and low residual oil saturation. The flow capacity of Class G flow units is second, Large area, medium - weak flooding, the remaining oil is relatively rich, is the next major goal of tapping the potential.
