چکیده:

Accurate prediction of relative permeability for various reservoir rocks at various saturation conditions has been of concern for a long time in petroleum industry. Relative permeability is known as one of the most significant parameters in simulation of actual multi-phase flow through porous media during life-time of a hydrocarbon reservoir. In addition, it plays important role in oil production and well completion. Direct experimental measurement in order to determine relative permeability of porous rock has long been recorded in petroleum related literature. However, empirical methods for determining relative permeability are becoming more widely used, particularly with the advent of digital reservoirsimulators. In this paper, a new generalized model for prediction of two-phase relative permeability is proposed which just utilizes end-points of phases. Furthermore, experimental studies on Berea sandstone for two-phase (water-oil) system are done during drainage process. The relative permeability curves predicted by proposed model are in good harmony with experimental results and compared to Corey and Naar-Henderson models, the proposed model has more accuracy
