Abstract
The method for determining equilibrium wettability of an interface between a void space and a solid phase of a rock sample comprises obtaining a three-dimensional image of the internal structure of the sample. On the obtained image of the internal structure of the sample, a void space and a solid phase are differentiated. An interface between the void space and the solid phase of the sample and distribution of minerals on this surface are determined. Wettability of the solid phase at each point of the interface between the void space and the solid phase of the rock sample is determined. A process of oil migration to the void space filled with stratum water at the initial stage of formation of an oil and gas field is numerically simulated, and finally, the equilibrium wettability of the interface between the void space and the solid phase of the rock sample is determined.
