摘　　要：模拟马寨油田卫95块地层渗透率、润湿性、温度、原油粘度及地层水条件,用仿真微模型首次对弱碱水复合驱驱油机理进行了研究。结果表明,最佳复合驱驱油体系以油珠变形、拉伸、形成油丝的方式启动剩余油。Formation permeability, wettability, temperature, crude oil viscosity and conditions of formation water in Block Wei 95 of Mazhai Oilfield are simulated, a micro-simulating model is used for the first time to study the displacement mechanism of alkalescent water composite flooding. The result indicates that the optimal composite displacement system is to drive remaining oil by ways of oil bead deformation, stretching, and forming oil threads.
