| Popis: | Water pressure system of Southern Pre-Uralian groundwater and man-made changes to it in the areas of hydrocarbon production are considered. The hydrogeological zoning is given and the aquifers complexes based on geological structure of the region are represented. The hydrodynamic connection of aquifers through halogen-sulfate deposits Iren' horizon of Kungurian stage, separating the upper and lower floors of underground water is proved. In the development of and gas fields decreased reservoir pressure and change levels of reservoir water. According to model of reservoir pressure dynamics with time after the cessation of hydrocarbon production, at the Orenburg gas condensate field the influx of water from the surrounding aquifer the recovery pressure to 50% from 7 to 15 MPa occured after about 500 years, and to 97%, to 20 MPa after 1500 years. |
