Claims (1)

Вторичное вскрытие продуктивных пластов газовых скважин при депрессии и равновесии на пласт с ускоренной очисткой призабойной зоны пласта газовых скважин, включающий спуск НКТ до искусственного забоя, перевод скважины на жидкость вторичного вскрытия пласта, установку воронки НКТ на 10 м выше выбранного интервала перфорации и последующую перфорацию продуктивных пластов, отличающееся тем, что после установки воронки НКТ на 10 м выше выбранного интервала перфорации, газом из соседней освоенной скважины куста, или инертным газом при помощи компрессора высокого давления, вытесняют жидкость вторичного вскрытия из скважины до создания равновесного давления или депрессии в интервале перфорации, перфорируют нижние 5-10 м интервала, вызывают приток газа, производят отработку скважины до полного выноса техногенных жидкостей из скважины газом и очистки призабойной зоны пласта, производят сокращенный комплекс газодинамических исследований, после чего перфорируют оставшуюся верхнюю часть продуктивного пласта при равновесии в газовой среде с последующей кратковременной отработкой и проведением полного комплекса газодинамических исследований.Secondary opening of productive strata of gas wells during depression and equilibrium to the stratum with accelerated cleaning of the bottom-hole zone of the gas well stratum, including lowering the tubing to artificial bottom hole, transferring the well to the secondary opening fluid, installing a tubing funnel 10 m above the selected perforation interval and subsequent perforation of the productive strata, characterized in that after installing the tubing funnel 10 m above the selected perforation interval, with gas from a neighboring well in the bush, or with an inert gas using high-pressure compressor, displace the secondary opening fluid from the well until equilibrium pressure or depression is created in the perforation interval, perforate the lower 5-10 m of the interval, cause gas to flow, produce a well until the technogenic liquids are completely removed from the well by gas and clean the bottom-hole formation zone, a reduced set of gas-dynamic studies, after which the remaining upper part of the reservoir is perforated at equilibrium in a gaseous medium with subsequent short-term development oh and conduct a full range of gas-dynamic studies.
