APPARATUS FOR GENERATING AN ULTRA-SUPERCRITICAL WORKING FLUID Russian patent published in 2020 - IPC E21B36/00 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to equipment for oil and gas industry and can be used for generation of working agent of high temperature and pressure. Plant comprises a water treatment module, an ultra-supercritical working agent generation module, a first pump unit for feeding water from the water treatment module to the ultra-supercritical working agent generation module, to the output of which there connected is a line for discharging the generated working agent to the well, as well as a separator and a line for separation of the separated water supplied to the separator. Separator inlet is connected to discharge line of working agent generated in the module, and in this line pressure reducer is installed, which is intended for reduction of pressure supplied to separator of working agent. Second pump unit, cooler, storage tank and third pump unit are built in series to separate separator from separator. Controlled shutoff valve is arranged at outlet of said line. Between which and the third pump unit, a main line is connected to the line by an input and connected to a water treatment module by an output, wherein in this line a controlled shutoff valve is installed.

EFFECT: higher efficiency of the plant due to reduced losses of the obtained working agent before its injection into the well.
