Experimental Determination of Steam Water Relative Permeability Relations
Abstract/Contents
- Abstract
- A set of relative permeability relations for simultaneous flow of steam and water in porous media have been derived from experiments conducted under conditions that eliminate most errors associated with saturation and pressure measurements. These relations show that the relative permeability for steam phase in porous media varies linearly with saturation. The liquid phase, however shows a variation close to that observed by Corey (1954) in water/gas experiments. This departure from the nitrogen/water behavior indicates that there are fundamental differences between steam/water and nitrogen/water flows.The saturations in these experiments were measured by using a high resolution X-ray computer tomography (CT) scanner. In addition the pressure gradients were obtained from accurate measurements of liquid phase pressure over portions with flat saturation profiles. These two aspects constitute a major improvement in the experimental method compared to those used in the past.Comparison of the saturation profiles measured by the X-ray CT scanner during the experiments shows good agreement with those predicted by numerical simulations. To obtain results that are applicable to general flow of steam and water in porous media similar experiments should be done at higher temperature and with porous rocks with different wetting characteristics and porosity distribution.
