Modeling of the mechanism of generation, accumulation and hydrocarbons migration ways in the south-caspian basin
The aim of this work is to study the mechanisms of generation, migration, accumulation and spatial distribution of hydrocarbon accumulations in the section of the South Caspian basin. Geological modeling of the space-time filling and deepening of the sedimentary basin is presented with account of the accompanying processes of thermo-catagenetic transformations of generation processes, migration of hydrocarbons and their accumulation in deposits. The study of the processes of hydrocarbons migration and accumulation confirms once again that the dominant form of natural fluids flow is the inter-formational (inter-stage) pulsation-injection subvertical migration along the conductive disjunctives planes, increased fracturing and decomposition zones, contacts of diapiric implants, eruptions of mud volcanoes, lithofacies disagreements and other disturbances of rocks continuity. Analysis of the studies and modeling of the oil and gas potential of the South Caspian basin confirms that large accumulations of hydrocarbons in deposits and fields are mainly closely related to mud volcanism and thermobaric conditions. Simulation of this system gives grounds to use the results obtained for further researches and projection of exploration works.
