摘　　要：本文综述了CO2对储层渗透率和储层岩石润湿性的影响、CO2与水间的相互作用,以及CO2、水与矿物(石英、硅酸盐和碳酸盐等)之间的相互作用。指出储层物性的改变会直接影响CO2的封存和EOR的效率;二氧化碳注入储层后,与地层水、储层岩石之间发生复杂的矿物溶蚀和沉淀作用是改变储层物性的直接原因。本文给出了大量可能发生的化学反应,讨论了影响反应速率的因素、研究中存在的问题和发展趋势,为今后实施CO2封存和EOR提供参考。This study presents an overview on some related results,including the effect of CO2 flooding on permeability and wettability of the reservoir formation,CO2-water interactions and CO2-water-minerals（quartz,silicate and carbonate） interactions.The authors consider the efficiency of CO2 sequestration was controlled by the variations of reservoir properties.After CO2 having injected into the right reservoir formation,complicated interactions of CO2-brine-rock are important reason for the change of reservoir properties.This paper presents a large amount of the potential chemical reactions and factors that affect the rate of reactions to provide the reference for further studies on CO2 sequestration and EOR.In addition,existing problems and the development tendency are also discussed.
