SYSTEM FOR AUTOMATICALLY ADJUSTING ENERGY-SAVING TECHNOLOGICAL MODE FOR OPERATING A GAS WELL Russian patent published in 2007 - IPC E21B47/10 

FIELD: engineering of equipment for automatically controlling and monitoring technological processes, possible use in gas industry during extraction and underground storage of gas.

SUBSTANCE: in internal adjustment contour system contains gas flow indicator (well debit indicator), mounted at line of gas outlet from well, automatic gas flow controller (automatic well debit controller) and adjusting choke, mounted at gas outlet line of well. gas flow indicator is connected to first input of well debit controller, and output of well debit controller is connected to adjusting choke. Additionally system contains acoustic pressure indicator in internal control contour, mounted on well face, automatic controller of acoustic pressure and acoustic pressure master. Acoustic pressure indicator is connected to first input of automatic controller of acoustic pressure, and to second one - acoustic pressure master is connected, while output of automatic controller of acoustic pressure is connected to second (setting) input of automatic well debit controller.

EFFECT: maintenance of energy saving debit of well and increased reliability of gas extraction, and also decreased gas recovery coefficient of bed.
