摘要
早期注聚油田由于所处的开发阶段存在多种增产调整手段，部分生产井的聚驱效果判断难度较大。探索了2种数值模拟新方法：利用ECLIPSE示踪剂关键字技术结合分层系分析，判断生产井含水下降漏斗是否为聚驱效果；利用物质平衡理念结合数模流体分区，进行物质平衡流量计算和统计，判断注聚井组和外围生产井的聚驱效果。新方法在一定程度上解决了早期注聚油田中聚驱效果判断的难题，对早期注聚油田开发调整具有指导意义。
It is difficult to judge the effect of polymer flooding in production wells due to different kinds of adjustment and stimulation used in the development stage of oiffields with early polymer flooding. Two new numerical simulation methods are explored： to judge whether the water-containing cone of depression is the effect of polymer with ECLIPSE tracer key point technology combined with strata series analysis; to judge the polymer flooding effect on polymer-injection pattern and surrounding producers with material balance theory combined with technique of area division by numerical modeling fluid calculating and collecting the statistics of material balance flow. The new methods solve the problem of judging the effect of early polymer flooding in oilfield to some degree and are significant for guiding the development adjustment in oilfields with early polymer flooding.
