METHOD OF OPERATION OF SELF-EXTRACTING GAS WELL Russian patent published in 2018 - IPC E21B43/22 C09K8/514 C09K8/536 

FIELD: oil production industry.

SUBSTANCE: invention refers to the oil and gas production industry, in particular to the operation of gas wells at the final stage of development, in the mode of self-pressing. Method of operating a self-extracting gas well, which involves the introduction of a foaming agent on the bottom of the well in the form of solid blocks with a surfactant - SBS, amount of which is due to the sufficiency for foaming the accumulated fluid on the face and bringing it to the surface, the composition of the base of these SBSs being the same, a portion of said SBSs are pre-coated with a gelatin shell, and the casings for the SBSs have different dissolution times. Invention is developed in subclaim.

EFFECT: technical result is an increase in the period between treatments of the surfactant well, an increase in its productivity due to the absence of a negative influence of the liquid column throughout the time between treatments.
