摘　　要：最小混相压力是确定低渗透油藏注气技术适应性的重要指标之一。通过对国内外文献资料的调研,分为实验测定与理论计算两大类详细论述了各种最小混相压力的确定方法,介绍了各种方法的适用条件以及优缺点,通过实例计算对比了通过各种方法确定的最小混相压力,提出了最小混相压力研究中存在的问题,进而为注气提高采收率技术的高效、合理开发奠定理论基础。The research of determining methods of minimum miscible pressure is the foundation of efficient development ofgas flooding for EOR in low permeability reservoirs. The determining methods of minimum miscible pressure both by experimentaldetermination and by theoretical calculation are discussed in detail. The application conditions as well as merits and demerits amongthe methods are given. The minimum miscible pressures determined by different methods are compared. These can help to provide atheoretical foundation for the efficient,rational exploitation of gas injectiontechnology.
