Method and device for utilizing flow separated from oil gas water separator for integral generation

Abstract

The invention relates to a comprehensive power generation method and a device thereof, which uses high-pressure high thermal energy fluid separated by an oil-gas-water separator, and adopts the method that the water processed by the oil-gas-water separator is discharged from a water outlet pipeline, and then enters a hydroelectric generator unit and / or a geothermal water power generation unit, wherein, the hydroelectric generator unit uses pressure energy and mechanical energy for producing water to drive a generator to generate power and uses geothermal energy of the produced water from separation to drive a steam turbine to generate power, and uses terrestrial heat for heating, thereby realizing the comprehensive, high-efficient and cascade utilization of the energy of the strata output; the gas processed by the oil-gas-water separator enters a turbine power generation unit via a natural gas outlet pipeline and is used for driving the steam turbine to generate power. The method has the beneficial effects that the pressure energy, thermal energy and gravitational potential energy of the water and the gas processed by the oil-gas-water separator are comprehensively used for pushing an impeller of a prime motor to rotate and driving the generator to generate power, thus realizing the purpose of using the residual energy and pressure producing the discharged water and gas for pushing the water turbine or a gas turbine to generate power, realizing the utilization of the residual energy and pressure, providing clean and unpolluted power source for oil fields, reducing the consumption of fossil energy, and realizing energy conservation and emission reduction.
