| 摘 要： | 针对低渗透油藏的地质及开发特点,在PVT实验和相态拟合的基础上,应用数值模拟技术研究了天然气驱开发方式对开发效果的影响。研究结果表明,注天然气可以较大幅度的提高低渗透油藏的采收率;气水交替驱是最佳的开发方式,并且水驱后气水交替驱的效果比投产初期就采用气水交替驱效果更好。 |
| 关 键 词： | 低渗透油藏 天然气驱 数值模拟 气水交替 非混相驱 开发方式 |

| Abstract: | In view of geologic and development characteristics in the low - permeability oil reservoirs and based on PVT experiments and phase behavior match, the influence of the development mode of natural gas drive on the effectiveness was studied by the use of numerical simulation technique. The results shows that the natural gas flooding can enhance oil recovery largely in the low - permeability oil reservoirs, water - gas alternating flooding is the optimal development mode, and the effect of WAG flooding after water flooding is better than the one of WAG flooding in the early production stage. |
| Keywords: | natural gas flooding numerical simulation water alternating gas immiscible flooding development mode |
