Abstract

RQI (Rock Quality Index) and FZI (Flow Zone Index) have proved to be effective methods of dividing the flow unit in the carbonate reservoir of the R oil field. The method utilizes the porosity and permeability of the core rock samples to divide the flow unit. The field consists of six flow units, and they represent different flow characteristics. The FZI can be accurately predicted by establishing a mathematical model of the log curves where core is not available, and the FZI/DRT (Discrete Rock Type) model of the whole reservoir is established by geostatistics method. With the DRT model and the porosity model, the permeability model can be estimated by using the characteristics of each flow unit with unique porosity-permeability relationship. The results show that the permeability model established by this method does not require a perm multiplier, the difficulty of curve fitting is greatly reduced and the work efficiency is improved in the numerical simulations.
