ABOUT ENS URING ENVIRONMENTAL SAFETY OF WATER RESERVOIRS OF ECONOMIC-DRINK PURPOSE OF OIL-FARMING OF ORENBURG REGION

In the oil and gas bearing areas of the Buzuluk depression with water resources deficiency and the development of environmental pollution (OC) processes, zones of groundwater concentration have been identified, both in the upper and lower hydrodynamic floors, in order to ensure water and environmental safety of the region, and oil fields - technical water for systems Maintaining reservoir pressure. We have established that the zones of concentration of fresh groundwater are gravitating toward riverine areas and are practically absent in their parts. They are vulnerable to pollution, and they can be used as indicators of the state of the OS. To protect water resources from pollution, it is recommended to place the projected engineering infrastructure, taking into account the scheme of typing the territory for protection against pollution, built by us. To protect groundwater from pollution, barrier technologies should be used, a number of which have been developed by the authors. Our geological-geophysical and neotectonic analysis of hydrogeological materials made it possible to identify the zones of concentration of brines and saline waters, which it is advisable to replace fresh water in the systems of maintaining reservoir pressure. For the same purpose, it is necessary to utilize wastewater from oilfields that can not be effectively cleaned. The proposed set of measures will increase the level of environmental safety of the oil producing regions of the Orenburg region and with the same purpose can be used in other similar regions.
