针对目前油田注采分析存在的困难 ,提出了用动态测井资料确定油水井注采关系的方法。利用注产剖面测井资料得出分层注水量和分层产液量 ,以此为基础结合井口生产数据 ,生成一定时间的产液、吸水量数据序列 ;根据灰色关联分析法确定油、水井连通性、注水受效时间 ;根据多元回归分析法确定注水井对周围油井不同层的水量分配。这种方法在大庆油田萨北过渡带 112口油、水井注采分析中取得了预期的效果。
Aiming at the difficulties existing in oilfield injection and production analysis, a method to determine the relationship between injection and production of oil and water wells by dynamic logging data is proposed. Based on the well production data and stratified production, the data of production fluid and water absorption of a certain period of time are generated, and the oil and water wells are determined according to the gray relational analysis Connectivity, water injection time; according to multiple regression analysis method to determine the injection wells on the surrounding oil wells in different layers of water allocation. This method has achieved the expected results in the analysis of injection and production of 112 oil and water wells in the Saibei transitional zone of Daqing Oilfield.
