| 摘要: |
| 在与三次采油油藏筛选标准对比、与国内外已实施三次采油区块类比以及气源条件分析、最小混相压力计算 和油藏数值模拟等研究的基础上,进行冀东油田深层中低渗透油藏气驱适应性分析。研究表明:水气交替烃类气驱 为该油藏优选的三次采油技术;南堡油田的发现为烃类气驱提供了充足的气源,气驱过程中可达到混相或近混相; 气驱技术实施后可有效地提高原油采收率，获得较好的经济效益。 |

| Abstract: |
| Based on the research of comparison with screening criteria of tertiary oil recovery reservoir, analogy to developed blocks with enhanced oil recovery in China and abroad, analysis of gas source conditions，calculation of minimum miscibility pressure and reservoir simulation, adaptability analysis of gas flooding was conducted for deep reservoir with low to medium permeability in Jidong Oilfield. Research results show that the optimum technology is water alternating hydrocarbon gas injection. The foundation of Nanpu Oilfield provided sufficient gas sources and it is possible to reach the state of miscible phase or near miscible phase. It is efHcient to enhance oil recovery and obtain considerable economic benefits after application of gas flooding technology. |
