METHOD OF DEVELOPMENT AND OPERATION OF WELLS WITH USE OF DISSOLVED GAS AND INSTALLATION OF INSTALLATION FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC E21B43/12 

FIELD: soil or rock drilling; mining.

SUBSTANCE: group of inventions relates to a method of development and operation of wells using dissolved gas and a method of mounting an installation for its implementation. Method involves accumulation of gas released from the gassed fluid at least under one packer to bypass pressure exceeding the pressure inside the tubing string. Accumulated gas is bypassed via bypass device or device from under packer inside tubing string. Additionally, at least one acoustic radiator is forced by forced release of gas from the gassy fluid at least under one bypass device with possibility of regulation and control of the process of forced release of gas depending on supplied power of the signal from the acoustic generator. At that intensity of gas accumulation under packer is changed. For this purpose, inclusion of emitters is performed simultaneously or in series, thereby controlling intensity of forced release of gas. At least one acoustic radiator is switched on or off periodically for a given period of time or according to a predetermined program. Volume of forced gas is pre-set by adjusting the distance between packer and productive formation, increasing or decreasing it. First, depth interval or specified depth of packer arrangement is defined with possibility of creating volume of under-packer space for gas accumulation with preset bypass pressure. Bypass of forced gas is performed periodically with possibility of periodical development of well during its operation. Depending on the amount of dissolved gas in the gassy fluid, the number of acoustic emitters in the apparatus is determined.

EFFECT: technical result is increased intensity of development and efficiency of operation of production wells, especially gas lift and fountain, due to increased inflow of carbonated fluid from formation at forced release of dissolved gas and its accumulation in sub-packer zone.
