Synthetic water-hydrocarbon inclusions in quartz, as evidence of the possibility of oil and gas formation in the process of interaction of bituminous rocks with hydrothermal solutions
The article provides experimental data on the phase composition, state and transformations of liquid and gas hydrocarbons (HC), based on the use of synthetic fluid inclusions in quartz. The experimental novelty of the research was that the growth of quartz with trapped inclusions was carried out in the same experiments in which the interaction of bituminous and carbonaceous rocks with hydrothermal solutions took place in the temperature range 240 - 550 °C and pressures of 7 - 150 MPa. As a result, it was proved that bituminous and carbonaceous rocks are an almost inexhaustible source of liquid and gaseous hydrocarbons and, upon reaching certain temperatures and pressures, are capable of active migration in the Earth's interior in the form of homogeneous supercritical fluids.
