SIMULATED COMPLETION METHOD FOR GAS WELL PRODUCTIVE FORMATIONS Russian patent published in 2014 - IPC E21B43/11 E21B43/27 

FIELD: oil and gas industry.

SUBSTANCE: flow sting with a re-entry guide is run in up to the perforated interval. Through the flow string to the perforated interval one or several shape-charge perforators are run in at the logging cable, depending on the interval size, the perforators are equipped with a connected container filled with a chemical compound, for example, with foam compound or gas- and foam generating composition. At first the container is actuated by breaking the protective shell. The chemical compound reduces density of the solution inside the perforated interval of the well, in result depression is formed (P_ar>P_bth). The perforators are ejected. When in result of perforation communication with the formation appears, the foamed liquid (aerated mixture), remains of the drill mud are lifted to the surface by the gas flow.

EFFECT: reducing labour and material costs to perform measures on the well cleaning from drill mud, industrial liquids, hydrates and improving quality of simulated completion, reducing time of the well transfer to the optimum process conditions.
