摘　　要：运用油藏工程和数值模拟方法 ,对孤岛中二中东区稠油油藏进行提高开发效果研究 ,以选择合理的开发措施 ,形成配套的应用技术 ,提高油田最终采收率。研究结果和现场应用表明 :采取相应的堵水提液措施是控制水侵的重要手段 ;一定量的边水 ,能补充注蒸汽的能量 ,有利于提高开发效果。通过实施配套工艺技术 ,累积增油 2 1 2× 10 4t,减少作业费用 2 699 5×10 4元 ,预计可提高采收率 8 4 % ,增加可采储量 2 4 3 6× 10 4t。Reservoir engineering and numerical simulation are utilized for improving development result of heavy oil reservoir in Gudao Zhong 2 middle-east area. In this way to screen out reasonable development measures, develop suitable matching techniques and achieve better final recovery. Study result and site application demonstrate that appropriate water blocking is key to control water invasion. A certain amount of edge water, however, will complement the steam injected and increase better development results. When matching techniques put into practice, the accumulative oil production reaches 21.2×10 4 t,operation cost lessens RMB 2.669 5×10 7, the increase of recovery rate and the recoverable reserve are 8.4% and 2.436×10 5 t, respectively.
