摘要: 自1993年以来,大庆油田先后开展并结束了5次三元复合驱矿场试验。为评价试验效果,在第3次试验即杏二区西部三元对复合驱结束后钻了杏2-2-检试1密闭取心检查井,从井网、注采关系及取心目的层PⅠ3层的空间分布上看,该井是很有代表性的。对杏树岗油田北部PⅠ3层密闭取心检查井水驱与三元复合驱的驱油效率对比分析表明,两种不同的驱替方式具有相同的驱油效率,说明三元复合驱的优越性并没有显示出来,所以仅从提高采出程度对三元复合驱效果作简单评价是远远不够的。

Abstract: Since 1993,five times of alkali-surfactant-polymer (ASP) flooding pilots have been engaged in Daqing Oilfield. After the third pilot,a closed coring and inspecting well,named Xing2-2-Jian p1,was drilled in order to evaluate the flooding results. The comparison of the efficiencies of water flooding and ASP flooding in the coring well of the northern Xingshugang Oilfield shows that the advantages of ASP flooding is not obvious,which shows that it is not enough to evaluate the effectiveness of ASP flooding only by using recovery factor. The evaluation standard for ASP flooding should be further studied.

Key words: Daqing Oilfield, alkali-surfactant-polymer flooding, oil displacement efficiency, development result, evaluation
