Hydrodynamical features development and oil deposits in Caspian Paleozoic
The results of experimental studies of oil recovery factor in the displacement of oil by water on the example of oil -giant fields in the Carboniferous deposits of the Caspian region, which can be used in the exploration and exploitation of the Paleozoic deposits in the waters. Presented various research organizations to determine the permeability of Paleozoic rocks, as well as the capillary pressure phase "oil-water ". Observed dependence of residual oil saturation on the permeability of the rocks, which is expressed by mathematical law. Graphically shows the relative permeability to oil and water, and depending on the capillary pressure of water saturation, which can be expressed by the equation regressive dependence. Determining capillary pressures of the gas saturation method is carried out on samples of discharge rocks. Experience in the development of Paleozoic oil is an important confirmation of the high petroleum potential of Paleozoic sediments in the North Caspian Sea, as success of exploration of such deposits is 100 %.
