Increasing the production of gas condensate by using ammonium carbonate salts

The work is devoted to the problem of increasing gas condensate production in fields. It was found that ammonium carbonate salts, absence calcium chloride type waters, interact with rocks, increase permeability reservoirs. Solutions salts when interacting formation water form chemically precipitated chalk pore space, while rocks decreases. A set experimental studies carried out study displacing and washing properties salts. have high properties, displacement ratio kerosene by NH 4 HCO 3 solution 0.75-0.80, reservoir – 0.55-0.58. According results laboratory characteristics conclusions were made about effect bicarbonate (ammonium salts) on a well conditions at temperatures 80-100 °C above. Industrial tests showed an flow 30-50% wells № 23 Opishnia, 115 Mashivka, Tymofiivka treatment achieved due clearing bottom zone permeability. At 56, 108 Yablunivka 58 fields, observed 22-35%. effectiveness this associated simultaneous bottomhole cleaning from asphalt-resinous contaminants increase, as hydrophilization space mobility result carbon dioxide effect, which rejected decomposition carbonate. Thus, industrial Tymofiivka, fields Poltava region confirmed using hydrocarbon production. prospect further research aimed developing technology for liquid hydrocarbons
