| 摘 要： | CO2吞吐是一种改善复杂油藏开发效果的有效方法,针对致密油藏多级压裂水平井的应用还不多见,其影响因素还不明确,潜力评价方法也不成熟。本文针对加拿大B油田实际情况,从转吞吐时机、周期注入量、注入速度和焖井时间四个方面对CO2吞吐的影响因素进行了综合分析。在此基础上,利用响应面方法建立了CO2吞吐潜力评价模型,提出了CO2吞吐潜力预测的新方法。

| Abstract: | CO2 huff and puff is an effective method for improving complex reservoir development effect. For the application of multi-stage fracture horizontal well in the tight reservoir are rare, and its influence factors is not clear, potential evaluation method is not mature. According to the actual situation of B oil field, four influence factors on the effect of CO2 huff and puff, such as time to huff and puff, injection volume, injection speed, soaking time are synthetically evaluated and analyzed. On this basis, established a potential prediction model of CO2 huff and puff for multi-stage fracture horizontal well, presented a new method to predicted the latent capacity of CO2 huff and puff. |

| Keywords: | tight oil reservoir multi-stage fracture horizontal well CO2 huff and puff potential prediction model |
