摘　　要：应用杏二区中块三采试验区丰富的静、动态地质资料 ,以密井网条件下的精细储层描述和构造描述为基础 ,对 16口取心井资料做多元逐步回归分析 ,建立了砂体厚度、沉积微相与岩性、物性参数之间的关联式 .利用关联式可求取生产井储层物性参数 ,确定表征存储能力和渗流能力的存储因子和渗流因子 .运用聚类分析方法 ,定量划分该区块主力油层的流动单元 ,并采用储层模式预测描述法在平面上划分流动单元 ,实现了对储层平面非均质性的进一步描述 .根据示踪剂检测和动态监测资料检验了划分流动单元的结果 ,表明示踪剂推进速度。Using abundant dynamic and static data of tertiary oil recovery pilot area in the central block of Xing 2 area, based on detailed reservoir description and structure description results under the condition of infill well pattern, with multiple core data regression analysis of 16 wells, a correlation of sand body thickness, sedimentation microfacies, lithology and physical characteristic parameter was built. By using the correlation, many reservoir physical characteristic parameters of producer were calculated, as well as the storage factor and fluid flow factor ,which characterize the storage capacity and fluid flow capacity respectively. By using cluster analysis method, the flow unit of main pay zone in the block were divided quantitatively. By using predication description method of reservoir mode, the horizontally flow unit were divided; Further areal heterogeneity was described. The division results of flow units were vertified according to the tracer detection and dynamic surveillance method. The comparison indicated that the tracer moving speed, the relative water absorbtion quantity,and the relative liquid production all showed positive correlation with the fluid flow parameters.
