| 摘 要： | 秦家屯油田松南142 区块经多年开采已经进入高含水阶段，为分析注采关系、预测剩余油分布和提高原油采收率，在本区开展了储层流动单元研究。结合岩心、录井、测井资料，确定本区主要发育扇三角洲前缘水下分流河道、水下分流河道间、河口坝、席状砂4 种沉积微相，农Ⅷ ～农V 整体表现为一套扇三角洲前缘的进积式沉积。运用多参数模糊聚类分析将本区储层划分为由好至差的A、B、 C、D、E5 类储层流动单元，并依此确定了研究区储层流动单元类型的回判标准。在储层流动单元展布特征研究的基础上，对区内油、水井之间的注采关系进行了分析，并对剩余油分布的有利区带进行了预测。利用研究区生产动态资料对该研究成果进行检验，证明分析结果与油田实际生产状况吻合。

| Abstract: | The Songnan 142 block of Qinjiatun Oilfield has entered the high-water-contain stage after years of exploitation． In order to analysis the relation of inection to production，predict the distribution of remaining oil and promote the oil recovery，we have studied the reservoir flow unit in this area． On the basis of the drilling core and well logging data，we found that there were four microfacies in this area，including the underwater distributary channel，underwater distributary interchannel，mouth bar and sheet sand． The Nong VIII --Nong V area showed an integrand deposition of fan delta front． Using the multi-parameter fuzzy cluster analysis，we divided the reservoirs of this area into five reservoir flow units of A，B，C，D and E in decreasing order of frequencies，and built the standards of types of reservoir flow units． Based on the study of the distribution of reservoir flow units，we analyzed the injection-production relation between the oil wells and water wells and also predicted the favourable zones of remaining oil． The results with production performance data were checked，which showed the consistency of the theory analysis results and the actual production conditions． |
