DEVELOPMENT OF WELLS WITH USE OF EXHAUST GASES FROM DIESEL ENGINES Russian patent published in 1997 - IPC

FIELD: oil and gas industry. SUBSTANCE: to prevent formation of explosion-risky mixture, nitrogen is used. Nitrogen application technology requires complex cryogenic equipment, delivery of nitrogen from production plant in liquid state at temperature of -160 C and its subsequent evaporation at temperature of 20 C, compression, and injection into well. Realization of this process in areas of oil fields remote from large industrial centers is very difficult and expensive. At same time, surrounding atmosphere contains 79% of nitrogen and 21% of oxygen. Exhaust gases of diesel engine contains 79% of nitrogen and up to 0.9% of products of incomplete combustion of diesel fuel (carbon monoxide, nitrogen oxide, benzopyrene, etc.) because oxygen is used up for oxidation of fuel. Offered is utilization of exhaust gases of diesel engine which drives compressor in function of inert gases in development of oil and gas wells. This closed-cycle technology: diesel engine - compressor - well intensifies well development process, sharply reduces expenses, prevents air pollution. EFFECT: high efficiency. 3 dwg
