Аннотация

By data of laboratory studies of mineral composition, analytical estimation of hydrophobicity of rocks by adsorption and NMR methods, pyrolytic studies of organic matter of Bazhenov Formation rocks, dependencies were determined between organo-mineral matrix composition and wettability of the solid surface. Influence of secondary effects on changes in hydrophobization of rocks were revealed. For carbonate minerals, catagenetic substitution of calcium cations for magnesium and iron results in polar changes in attitude of the rock to water fluids. Evaluation was made of the proportion of generated autochthonous and parautochthonous hydrocarbons of the oil series, heteroatomic compounds and kerogen in the overall balance of the organic component of the Bazhenov rocks, and an attempt was made to establish dependency of these proportions versus measured hydrophobicity of rocks. After dissolution of the light fraction of petroleum hydrocarbons, a decrease in combustion rate of the residual organic matter in air flow was observed for hydrophobic varieties. There are no obvious dependencies of surface hydrophobization versus mineral composition and organic matter of a rock in the 'rock-water-oil' system.
