Abstract

Abstract

NMR (nuclear magnetic resonance) method is used to obtain the property of porous media without damage. But the measurement of wettability in the porous media is still in quasi-quantitative. The capillary and surface tension methods are used to measure the relationship between the concentration of the reagent and the wettability of the glass plate. And then the wettabilities of the porous media are demarcated by NMR and the scales of a series of porous media are obtained. The results of analysis indicate that the variation of wettability in porous media corresponds with the measured data under the condition of dichlorodimethylsilane concentration from water-wet to oil-wet (?) from 0% to 0.7%. If out of this range, resonance time still increases with the concentration of reagent but it does not relate with the scale of the wettability.
