摘　　要：分析了大庆油田萨北过渡带地区四点法面积井网注聚过程中的动态变化特征及取得的试验效果 ,重点介绍了聚驱开发过程中所采取的综合调整措施。分析认为 ,在聚驱过程的不同开采阶段及时采取多种措施 ,如注入井的跟踪调整 ,采油井的增产措施等 ,可以有效地减少层间矛盾 ,延长采油井的有效期 ,改善注采状况。由于试验区地处过渡带 ,其井网、油层条件和原油性质具有特殊性 ,这些因素将影响过渡带地区聚合物驱油的开发效果。本次先导性矿场试验为今后过渡带地区工业化推广聚合物驱油技术 。This article analyzed the properties of the flow performance that present in polymer injecting by four spot pattern polymer injection in transitional zone of Sabei in Daqing Oilfield and the result of the test as well. Its main description is that the means of integrated modification that is taken into practice in polymer flooding. The analysis stated that taking different steps on different stages in polymer flooding such as injector modification and producer stimulation can decrease interlayer interference effectively, lengthen producing well validity and advance injection production. The test area whose well pattern, reservoir conditions and crude oil properties are special, which will affect the effectiveness of polymer flooding in transitional zone. Here, field pilot test has offered practical basis to spread the technology of polymer flooding, increase its application and lengthen stable production period in coming transitional zone.
