摘　　要：高渗透油藏具有典型的三高特征,即"高渗透率、高产能、高丰度"。我国的高渗透油气资源所占比例较低,但众多学者并没有放弃对高渗透油藏提高采收率的研究,其后期开采阶段的采收率有待进一步提高。本文基于人造高渗透岩心开展CO_2驱油实验,观察注入压力和注入PV数对最终油气采收率的影响。最终优选出最佳注入压力为12.1MPa,最佳注入PV数为2.0PV。High permeability reservoirs have three high characteristics, namely ＂high permeability, high pro- ductivity, high abundance＂. China＇s high penetration of oil and gas resources accounted for a lower proportion of its post-stage recovery phase of the recovery rate to be further improved. In this paper, carbon dioxide flooding exper- iments were carried out on the basis of artificial high permeability cores to observe the effect of injection pressure and implantation PV on the final oil and gas recovery. Finally, the optimum injection pressure is 12.1MPa, and the optimum implantation number is 0.62PV.
