摘要
大庆油田烃气非混相驱矿场试验手1989年4月在大庆萨中开发区进行。注气后改善了吸入和产出剖面，减慢了含水上升速度，累积产油比正常水驱增加了119829t，提高采收率4．3％，预计最终采收率可提高9．0％左右，经济效益显著，可获得纯利润9211．68万元，为投资的2．64倍。
The pilot test of natural gas immiscible flooding begins on April, 1989 at Sazhong developing area in Daqing. After WAG in-jection, the injection profile and the liquid production profile have been improved, the rising of water cut has been decreased.Comparing with the normal waterflooding, the cumulative oil production has increased by 119, 829 t, and oil recovery has al-ready been increased about 4. 3%. According to the prediction, the ultimate recovery can be increased about 9. 0%, and theeconomic efficient is noticeable. The pure profit obtained can be up to about 92 million Chinese Yuan, which is 2. 64 times ofthe investment.
