Claims (1)

Способ увеличения продуктивности эксплуатационной нефтяной скважины, включающий закачку в скважину оторочки газожидкостной смеси и последующее освоение скважины, отличающийся тем, что оторочку газожидкостной смеси закачивают в объеме 0,5 - 1 объема пор пласта в призабойной его зоне при кратности содержания газовой фазы 0,25 - 6 по отношению к жидкости в пластовых условиях, после чего в скважину последовательно закачивают газовую оторочку, состоящую из взрывобезопасного газа или смеси таких газов, и жидкую оторочку теплоносителя, причем объем газовой оторочки в пластовых условиях составляет не менее объема теплоносителя, вслед за чем указанную жидкую оторочку продавливают в пласт жидкостью, обеспечивающей глушение скважины, а освоение скважины осуществляют путем откачки жидкости глушения и последующего создания глубокой депрессии на пласт при подкачивании газового агента в затрубное пространство скважины до прорыва в последнюю газа из газовой оторочки.A method of increasing the productivity of a production oil well, including injecting the rims of the gas-liquid mixture into the well and subsequent development of the well, characterized in that the rim of the gas-liquid mixture is pumped in a volume of 0.5 - 1 pore volume of the formation in its bottom zone with a multiplicity of gas phase content of 0.25 - 6 in relation to the fluid in the reservoir conditions, after which a gas rim consisting of an explosion-proof gas or a mixture of such gases and a liquid rim of the coolant are sequentially pumped into the well, the gas rim in the reservoir conditions is not less than the coolant volume, after which the specified liquid rim is pushed into the reservoir with a fluid that kills the well, and the development of the well is carried out by pumping the killing fluid and then creating a deep depression on the reservoir when pumping the gas agent into the annulus of the well before breaking into the last gas from the gas rim.
