摘　　要：注CO2 吞吐是提高复杂小断块油田采收率的有效途径之一,相态和数值模拟研究是确定目标区块吞吐可行性研究的重要参考依据。在注CO2 吞吐相态实验和CO2 粘温关系研究的基础上,对低渗纵向非均质油藏兴北S3 块进行可行性论证和数值模拟预测,同时对该区块CO2 吞吐的注采参数进行了数值模拟优化研究。结果表明:在辽河兴北S3 块进行CO2 吞吐具有较好的效果,模拟井组CO2 吞吐效果较好,在300d内可累积产油1 577t,累积增油410t,换油率达到2. 05。It is an efficient way for complex small faulted block to CO_2 injection and production. Phase behavior and simulation studying can help us much more of knowing whether the reservoir suits for this process. After phase behavior of Xingbei S_3 faulted block crude oil in Liaohe was studied, CO_2 injection and production from well Xing was simulated. Results indicated this block had good potential of CO_2 injection. It would be produced 1577t oil within 300 days. Ratio of CO_2 shift oil is up to 2.
