通过对国内外注CO_2技术应用现状调查,对比CO_2吞吐适用条件,证实了马北区块CO_2吞吐是可行的。在此基础上,根据实验分析和数值模拟结果对马北区块CO_2吞吐方案进行了优化设计,并对现场实施情况进行了效果分析,提出了下步改进吞吐效果的建议。 By investigating the application status of CO2 injection at home and abroad, comparing with the applicable conditions of CO 2 throughput, it is proved that it is feasible to huff and puff CO_2 in Mabei block. On this basis, based on the experimental analysis and numerical simulation results, the optimization design of the CO 2 huff and puff in the Mabei block was carried out. The effect of the site implementation was analyzed and suggestions for improving the throughput were put forward.
