چکیده مقاله:

displacement of oil water in porous media of reservoir rocks is described by relative permeability curves , which are importand input data to resevoir performance simulation and drive mechanism studies. Many core studies , such as multiphase relative permeability , capillary pressure and saturation exponent determination depend on the volume fractions of multiphase fluids present in the studied rock samples.X-ray scanners are increasingly used for measurement of fluids saturation in the core samples during core studies mainly due to expanding need of modeling and measuring reservoir condition fluids flow behavior and its safer issues than other radioactive sources like gamma-ray. incorporating X-ray in - situ saturation measurements into the rlative permeability , capillary pressure and intrinsic wettability characterization of reservoir rocks may imporve reservoir management and productivity prediction. this paper describes two - phase immiscible fluid flow behavior of oil displaced by water though water -wet porous media interpreted by X-ray data utility , according to saturation profile shapes incorporated by history matching of oil production and differential pressure history in low oil to water viscosity ratio fluid flow . in -situ saturation profiles have been obtained with 1% saturation accuracy.
