摘　　要：利用深部咸水层进行CO_(2)封存是缓解全球气候变暖的有效手段之一,作为获取地层信息最直接的手段,测井资料的应用对深部咸水层的评价至关重要。通过对咸水层评价的文献进行调研,得出咸水层矿化度、电阻率、纵波速度、孔隙度、渗透率以及渗透率各向异性是影响咸水层CO_(2)溶解机制、储存容量和储存时限的重要因素。其中,咸水层矿化度对咸水层的CO_(2)溶解机制和储存容量有直接的影响。在调研总结的基础上,重点讨论了咸水层矿化度测井评价方法,针对CO_(2)地质封存,对比了各种矿化度测井评价方法的优缺点,利用测井方法评价咸水层矿化度可为CO_(2)在咸水层中的地质封存提供重要的理论指导。The use of deep saline aquifers for carbon dioxide storage is one of the effective means to mitigate global warming.As the most direct means of obtaining formation information,the application of geophysical logging data is crucial to the evaluation of deep saline aquifers.Through the investigation of the current literature on the evaluation of saline aquifers,it is concluded that the salinity,reservoir resistivity,P-wave velocity,porosity,permeability and permeability anisotropy of the saline aquifers are the main factors that affect the CO_(2)dissolution mechanism and storage in the saline aquifers.Among them,the salinity of the saline aquifers is particularly important,which has a direct impact on the CO_(2)dissolution mechanism and storage capacity of the saline aquifers.On the basis of the investigation and summary,this paper focuses on the salinity log evaluation methods in saline aquifers.For CO_(2)geological storage,the advantages and disadvantages of various salinity log evaluation methods are compared.Evaluation of salinity of saline aquifers by logging method can provide important theoretical guidance for the geological storage of CO_(2)in saline aquifers.
