摘　　要：自然电位曲线是常用的测井曲线,应用方便。在测井储层评价过程中,依据自然电位曲线特征,结合岩心化验分析、地质研究成果,探寻自然电位曲线特征指示的各种地层因素及其地质意义,应用于地质分层、沉积相研究、储层物性判别等,实现测井与地质的结合,提高测井储层评价精度,拓展测井曲线资料的应用空间。Spontaneous potential(SP)curve is a commonly used logging curve,which is convenient to use.In the process of logging reservoir evaluation,based on the characteristics of the SP curve,combined with core laboratory analysis and geological research results,various stratigraphic factors indicated by the characteristics of the SP curve and their geological significance are explored.And then the research results have been applied to geological stratification,sedimentary facies research,reservoir physical property identification,etc.,to realize the combination of logging and geology,improve the accuracy of logging reservoir evaluation,and expand the application space of logging curve data.
