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1577t,累积增油410t,换油率达到2.05。

Abstract: It is an efficient way for complex small faulted block to CO2 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 S3 faulted block crude oil in Liaohe was studied, CO2 injection and production from well Xing was simulated. Results indicated this block had good potential of CO2 injection. It would be produced 1557t oil within 300 days. Ratio of CO2 shift oil is up to 2.

Key words: CO2, phase behavior, simulation, enhanced oil recovery
