摘　　要：目前水驱油藏窜流通道识别多借助于各类特殊监测资料,针对受资料条件限制而无法广泛应用的问题,提出了基于灰色关联分析的窜流通道识别新方法。该方法利用常规的生产动态资料和采油井、注水井的普通监测资料,通过计算注采单元内注水井的视吸水指数与任一采油井的产液指数间的注采关联度,判断该注采单元内注水井、采油井之间的连通性,进而确定窜流通道的发育方向。该方法在大庆葡北油田的应用结果表明,注采单元内注水井与采油井的关联度越接近于1,子序列与母序列之间的相关程度越高,则相关注水井和采油井之间窜流通道的发育几率越高。At present,the channeling path of water-drive reservoir is mainly recognized by using various production logging data,which can not be widely used because of limited data.Therefore,the identifying method of channeling path in water-drive reservoir based on injection-production relevance degree is proposed in this paper.Through using the production performance and logging data of producer and injector,and calculating the injection-production relevance degree of apparent water injectivity and production fluid index in flooding unit,the method is implemented to recognize the growth direction of channeling path.The application in Pubei Oilfield of Daqing indicates that the higher relevance degree of subfamily and predecessor is,and the more vegetal channeling path is when the closer to 1 the injection-production relevance degree of apparent water injectivity and production fluid index is.
