ULTRA-SUPERCRITICAL WORKING AGENT GENERATOR Russian patent published in 2020 - IPC E21B36/00 E21B43/24 F22B1/02 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to equipment for oil and gas industry and can be used for generation of ultra-supercritical working agent injected into petrocylogenic-containing formations. Generator of ultra-supercritical working agent contains the first heat generating module, in lower part of housing of which heat carrier is arranged, above which in housing cavity first, second and third heating sections are located. First heating section is located in the upper part of the housing and is equipped with an inlet header having the possibility of connection with the feed water supply line. Second heating section is located in the lower part of the housing directly above the device of heat carrier generation, its inlet is connected to the output of the first section, and by its output - to the input of the third heating section located in the cavity of the housing between the first and the second sections. At that, the generator is equipped with the second heat generating module, which includes heat carrier generation device, located in the housing lower part of this module, overheating section, a sealed container mounted in the housing above the heat carrier generation device, in which a closed circulation channel filled with a heat generating agent is formed. Generator is additionally equipped with a heat-generating agent circulation mechanism located in the circulation channel, in which the overheating section is also located, its input is connected to the output of the third section of the first heat-generating module, and the output can be connected to the user of the working agent.

EFFECT: technical result is higher efficiency and efficiency of generator, as well as reduction of its weight and size characteristics due to more efficient heating of overheating section.
