(57) Abstract: The present invention relates to mining and can be used to obtain salt from extracted along with oil and gas produced water. The inventive salt is produced from brine residue from the use of associated natural gas as fuel. As the brine used is extracted along with oil or gas produced water. The technical result - the expansion of raw materials, utilization of associated gas. The present invention relates to mining and can be used to obtain salt from extracted along with oil and gas produced water. It is well known that commercial production of table salt is made from natural deposits of rock salt, with subsequent grinding or from natural surface waters such as the Gulf of Kara-Bogaz-Gol, through natural evaporation in open ponds. A disadvantage of known methods is the rigid adherence to the deposits of salt and climatic conditions. Closest to the proposed technical solution is the way underground, the AK oil and salt reservoirs, pumping out oil and flaring of associated gas by using the heat produced by the heated leach solution, which is then pumped into the production well is then pumped out of them brine and using associated gas as fuel is evaporated brine, getting salt. The disadvantages of this method are the need to match deposits of salt oil field, which is relatively rare; the need for drilling production wells and injection preheated leach solution, the obtained pumping brine from wells, which significantly increases the cost of the process of obtaining salt. The tasks of the proposed method is an extension of the resource base to produce salt with simultaneous reduction of its receipt. This is accomplished by obtaining salt from the brine residue using associated gas as fuel, the brine used is extracted along with oil and gas produced water. The method is as follows. Example 1. Park primary oil treatment, where OI water using heat from gas flaring, moreover, depending on the composition of produced water, the residue is purified produced water produced at 80-95% of the original volume. In the process residue obtained brine periodically or continuously filtered with the mission of the Department of crystallization of salt and a drop of hardness salts. The remaining residue returned to the Park system primary oil treatment. To clean salt from hardness salts and other possible pollutants received technical salt dissolved in distilled water, filtered and the recrystallization of using heat from gas flaring get food table salt, and oparka lead to 93-98% of the original volume, and the remainder of the brine pumped into the system Park primary oil treatment. Example 2. Park primary oil treatment, where the separation of oil from produced water and associated gas, the standard equipment is the residue produced water using heat from gas flaring. In the process residue obtained brine periodically or continuously filtered with the mission of the Department of crystallization of salt and a drop of hardness salts. Get technical table Sol which separates the oil from produced water and associated gas, standard equipment is the residue produced water using heat from gas flaring, and, depending on the composition of produced water, the residue is purified produced water produced at 80-95% of the original volume. In the process residue obtained brine periodically or continuously filtered with the mission of the Department of crystallization of salt and a drop of hardness salts. The remaining residue returned to the Park system primary oil treatment. Get technical table salt. The proposed method provides the expansion of raw materials for the production of technical and food salt with simultaneous solution of the problems of disposal of produced water and useless flared associated gas. The method of obtaining salt, including the evaporation of the brine using the heat from combustion of produced oil gas, characterized in that as the use brine produced from oil and gas produced water.
