METHOD OF GAS PUMPING OUT FROM GAS MAIN SHUT-OFF SECTION AND MOBILE PLANT FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2018 - IPC F04D25/02 F04B41/00 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions refers to the repair of main or distribution gas pipelines. Method for pumping gas out of a shut-off section of a gas pipeline, which consists in that the shut-off section of the gas pipeline is connected to compressor 4 through pipelines and shut-off valves and pumped to the required pressure in the shut-off section of the gas pipeline. Gas from the shut-off section is pumped out by means of compressor 4, the parameters of the pumped gas are measured by means of instrumentation. Parameters are supplied to calculating unit 5, from which information is supplied to control unit 6, where it is analyzed, processed and generated into a control signal to compressor 4 for squeezing the pumped gas, after which the parameters of the compressed gas are measured and through calculating unit 5 the parameters are fed to control unit 6 to generate signals coming through telemechanics line 8 to the valves of cylinders 7, after which cylinders 7 are filled with compressed gas.

EFFECT: technical result consists in the mobility and automation of the system for pumping out, storing and storing gas from the sections of trunk pipelines, gas distribution pipelines and branch pipelines that have been repaired.
