【摘要】In order to understand the current situation of carbonate reservoir water saturation models,and to offer basic infor-mation for saturation evaluation in heterogeneous reservoir,this paper summarizes the current saturation interpretation models. According to study objects,conductive mechanism and study methods,the carbonate reservoir saturation interpretation models are divided into four types:Archie and its extended empirical saturation models,saturation models of dual and triple porosity system based on different porosity types,saturation models of dual and triple porosity system based on different porosity size, and saturation models based on effective medium theory. The conductive mechanism,assumption and application of different saturation interpretation models have been discussed. It points out that the Archie formula is concise,and always equivalent in the numerical sense after scaled by the data of experimental analysis and the triple-model will be the most conventional one that we expected currently,and based on the discussion we suggests that rock conductive mechanism,petrophysics experiment and the calculation of model parameters need further research,and that the pore network
