The results of an electron-microscopy study of hydrophobic organic layers in the pore space of carbonate rocks, which change the wettability of the formation, making the rock hydrophobic, are presented. This significantly affects the technology of hydrocarbon field development. A technique for studying adsorbed layers based on morphological analysis is proposed. The data of microprobe studies of organic layers are presented, showing a higher carbon content in them compared to calcite. The results of morphological studies of the structure of samples of carbonate rocks of an oil field are shown, which make it possible to identify and study organic adsorbed layers on the surface of mineral particles formed because of the adsorption of the polar components of matrix oil. The thickness of the organic layers is determined. [ABSTRACT FROM AUTHOR] |
