Abstract: This paper reviews the electric logging interpretation method that had been used before 1990's and introduces the study progress of PetroChina made in formation electrical property and electric logging interpretation method of low amplitude reservoir-low resistivity pay and pre-Cretaceous extra low permeability reservoir in the last decade. The progress includes clay additional electric conductivity in shaly sand, the influence of drilling mud invasion on response of dual lateral log and dual induction log, electric property of complex pore types and extra low permeability reservoir, and distribution law of logging saturation-resistivity in various reservoirs. The study progress indicates that the electric logging is an important method in reservoir evaluation.
