  • The quantitative characterization of petrophysical properties such as porosity, permeability, and saturation in 3D space has been a technical problem for the development of porous carbonate reservoirs. In order to establish a reliable geological model of porous carbonate reservoirs, taking reservoir F in the Zagros Basin as a prototype, a geological modeling method based on sedimentary facies coupled rock type was studied and put forward. Based on geological research, we combined well logging data with seismic data, and established a sedimentary facies model. Controlled by the sedimentary facies model, 3D distribution models of porosity and rock type were built. Then, based on the porosity-permeability mathematical model and saturation height function controlled by rock type, 3D permeability and water saturation distribution models were established by using deterministic modeling method. The results showed that the geological model established by using the proposed method was reliable, which laid a solid geological foundation for the development of reservoir F, and the method proposed in this paper could provide guidance for the geological modeling of this kind of reservoir.
