Петин А.Н., Немец К.А., Немец Д.К., Немец А.Д.
Methodology for assessing the prospects of oil and gas basins and separate structural-tectonic areas on the basis of a combination of atmospheric, hydrological, gas geochemical exploration groups of criteria is proposed. At the first stage examines the thermopressure conditions of the selected region, built cards dive certain isotherms and maps of reservoir temperature at the depth slices. Geothermal researches allow to highlight the positive geothermal anomalies and outline perspective areas with intensive тепломассопереносом. Geopressure researches are based on the study of the allocation by hydrostatic background and abnormally high reservoir pressure. At the second stage examines the structure of the water system of the region. Stand out The hydrodynamic zones and their hydrogeochemical characteristics are distinguished. The distribution of the concentrations of the components and micro-components of groundwater depending on the depth and modern reservoir temperatures is analyzed. At the third stage, we study the complex features of the allocated hydrodynamic zones. The dependencies densities of free gas concentrations of their components, the location and the size of the gas, gas condensate and oil deposits to the depths and modern reservoir temperatures are discovered. The technique allows to distinguish the advanced in search of hydrocarbon accumulations horizontal sections and vertical zones incision in the region.
