| 摘 要： | 多元热流体吞吐热采技术是一种新型的提高稠油采收率技术,目前在渤海湾NB-XX油田已经得到尝试并获成果,然而对于其降黏增产机理的认识并不清楚。通过模拟计算及室内实验研究,对多元热流体作用机理进行初步探讨分析,揭示了多元热流体增加稠油单井产能、改善稠油开发效果的作用机理,为该技术在其它稠油油田的运用提供了一定的理论依据。

| Abstract: | Huff and puff stimulation with multiple thermal fluids is a kind of new enhanced heavy oil recovery technology,and this heavy oil recovery technology has been used in NB-XX oilfield in Bohai Bay,with good oil recovery results.However,it is not clear about the viscosity reduction and enhanced oil recovery mechanism.Through mathematic simulation and laboratory experiments,the mechanism of multiple thermal fluids has been analyzed.Through this study,the mechanisms of increasing heavy oil productivity in individual well with multi-thermal fluids and improving heavy oil development effects have been made clear.It provides a theoretical basis for the application of this technology to other heavy oil fields. |
