WATER SATURATION OF THE PAYS IN MENGGULIN BRECCIA OF ERLIAN BASIN

With the analytical data on rock samples recovered by drilling mud with oil matrix, water saturation of the pays in Menggulin Breccia was evaluated. Volcanic breccia is highly water-saturated due to its fine pore geometry and poor physical properties; while gravelly sandstones and sandy conglomerates are low water-saturated with relatively high oil saturation.
