METHOD FOR OPERATION OF GROUP OF WATERING WELLS Russian patent published in 2019 - IPC E21B43/00 F17D1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the gas industry, in particular to the exploitation of gas wells in fields under conditions of falling gas production. Method of operation of a group of watering wells, which are equipped according to the packerless scheme and are united by one gas collector, includes the construction of a process pipeline from a modular compressor unit to a gas-flashing device. Technological pipeline connects the lower backward line of each well of the bush through remote-controlled valves. Each lower dividing line of the well is equipped with stop valves. Beginning of the elimination of the liquid column is determined by reducing the wellhead parameters from the established. Valves of the process pipeline and the bottom of the drop line of the well is opened. Compressed gas is supplied from the modular compressor unit to the annulus of the well. After the liquidation of the liquid column, the valves are closed. Gas is vented in the process pipeline to the gas torch device and continues to operate the well group.

EFFECT: increase the life of wells to enter the inactive fund.
