摘　　要：针对涠洲11-4油田主力油层——角尾Ⅱ油组换大泵提液、开发东区和高含水井侧钻等主要措施增产效果不理想的问题,以涠洲11-4油田生产历史数据为基础,通过对国内外大量文献的调研,利用建立的等效模型对涠洲11-4油田注气提高采收率方案进行了预测。结果表明,连续注气、间歇注气及水气交替这3种开发方案的开发效果较差,而泡沫驱方案增油效果明显,建议积极开展泡沫驱进一步实验和研究工作。In allusing to the problems of poor stimulation effects of fluid production with big pumps, development in east area and sidetracking in high water-cut wells in the main oil reservoir——Jiaowei Ⅱ Oil Formation of Weizhou 11-4 Oilfield at the late period of development, and based on historical production data of Weizhou 11-4 Oilfield, and by investigation of literatures both at home and abroad. An equivalent model was used to predict the enhanced recovery scheme by injecting gas in the oilfield. The simulation results show that the effect of continuous gas injection,intermittent gas injection, and water alternating gas is poor, but the effect of foam flooding is obvious and effective, it is suggested that further experimental study should be made on foam flooding.
