摘　　要：综述了自发渗吸提高采收率机理,包括毛管力、电化学力等,论述了复杂程度不同的页岩渗吸机理模型进展,为数值模拟优化提供参考,总结了自发渗吸提高采收率的控制因素,包括储层岩石、流体性质、温度及压力的影响。指出了自发渗吸提高采收率存在问题及发展方向,为未来提高页岩油渗吸采收率提供理论基础。The mechanisms of spontaneous imbibition to enhance oil recovery,including capillary force,electrochemical force,etc.,are reviewed.Imbibition mechanism models and influencing factors for shales of varying complexity are expounded.The factors which control spontaneous imbibition are summarized,including reservoir rock,fluid properties,temperature and pressure.The issues of spontaneous imbibition and the ways forward are noted,which provides a theoretical basis for improving EOR of shale oil in the future.
