摘要
针对江苏油田F14块的油藏条件和生产历史，设计了三种不同的三次采油方案（注烃类气体、注CO2、聚合物驱），并使用UTCOMP软件分别进行了数值模拟。结果表明注CO2混相驱替可以大幅度地提高原油采收率，并且由于江苏黄桥地区有充足的气源，注入成本较低，是这三个方案中最优的一个。
Three EOR methods(polymer flooding, dry gas injection and CO2 injection) were selected for F-14 Block of JiangSu oilfield according to its reservoir character and production history. Numeried simulation was carried out using UTCOMP, an compositional model with polymer option. The results show that CO2-miscble injection gives the highest recovry, and its driving efficiency is better than polymer flooding and dry gas flooding. Since the supply of CO2 is abundant with the discovery of a giant CO2 reservoir in JiangSu province,CO2 flooding will be a cost effcetive EOR method for the reservoir studied here.
