The work is devoted to the problem of increasing the production of gas condensate in gas condensate fields. It is established that ammonium carbonate salts, in the absence of chlorocalcium-type waters, interact with carbonate rocks, increase the permeability of reservoirs. Solutions of ammonium carbonate salts in interaction with formation water of the chlorocalcium type form chemically precipitated chalk in the pore space, while the permeability of carbonate rocks decreases. A set of experimental studies was carried out in order to displace and wash the properties of ammonium carbonate salts. It was found that ammonium carbonate salts have high displacing properties, the coefficient of displacement of kerosene by NH4HCO3 solution is 0.75-0.80, while reservoir water – 0.55-0.58. According to the results of laboratory studies of displacement and washing characteristics of ammonium carbonate salts, conclusions were made about the effect of bicarbonate solution (ammonium carbonate salts) on the production characteristics of the well in formation conditions at temperatures of 80-100 ° C and above. Industrial tests of ammonium carbonate salts showed an increase in gas flow by 30-50% at wells № 23 of Opishnya, № 115 of Mashivka, № 3 of Tymofiivka gas condensate fields. The effect of treatment of the formation with ammonium carbonate salts is achieved due to the cleaning of the bottomhole zone of the formation and increase the permeability of the reservoir. Condensate factor increase by 22-35% was observed at wells № 56, 108 of Yablunivka and № 58 of Tymofiivka gas condensate fields. Thus, experimental and industrial tests confirmed the effectiveness of using ammonium carbonate salts to increase hydrocarbon production. Prospects for further research are aimed at developing a technology to increase the production of liquid hydrocarbons through the use of ammonium carbonate salts.
