PLANT TO INCREASE RESERVOIR RECOVERY AND HEAT RECUPERATION OF EXHAUST GAS FROM GAS-TURBINE UNIT OF PETROLEUM INDUSTRY ENTERPRISE

摘要

FIELD: oil and gas industry.SUBSTANCE: heat recuperation plant for exhaust gas from a gas-turbine unit that uses associated petroleum gas and/or natural gas from development of hydrocarbon-bearing formation as a working medium includes afterburner, closed circulation loop of low-boiling organic compounds and compressor feeding exhaust gas to petroleum-bearing stratum, which are locates in-series along the flow of exhaust gas. For driving of compressor feeding exhaust gas to petroleum-bearing stratum energy is used that is produced at the shaft of gas-turbine unit and turbine with closed circulation loop of low-boiling organic compounds.EFFECT: invention allows increase of development intensity for petroleum and gas deposits and use of heat recuperated from exhaust gas of the gas-turbine unit operated by petroleum industry enterprise.1 dwg
