摘　　要：低渗透稠油油藏开发中面临注水困难、效果差等问题,注气驱是动用此类难采储量的有效方法之一。室内实验结果表明,烟道气—气水交替驱与CO2—气水交替驱能有效提高采收率,可作为首选注气方式。In low - permeability heavy oil reservoirs, the efficiency of oil recovery with water flooding process is poor or its development faces the problems of water injection difficulty. The experiment results in laboratory show that flue gas- gas/water alternating flooding and C02 -gas /water alternating flooding can improve effectively EOR. It＇s thought as the preferred way of gas injection.
