Claims (1)

Способ ликвидации зон поглощения в скважине, включающий размещение в скважине трубы, нижний конец которой установлен в интервале зоны поглощения, раздельно-одновременную подачу отверждаемого тампонирующего состава и газа в зону смешивания, связанную с верхним концом трубы, последующую закачку в скважину через трубу полученной газотампонирующей смеси и размещение этой смеси в зоне поглощения, отличающийся тем, что закачку газотампонирующей смеси в скважину осуществляют через трубу, нижний и верхний концы которой имеют уменьшенное проходное сечение, если давление в интервале расположения зоны поглощения находится в одном порядке с атмосферным, или через трубу, верхний конец которой имеет уменьшенное проходное сечение, если давление в интервале расположения зоны поглощения соизмеримо с давлением в этой трубе при закачке.A method for eliminating absorption zones in a well, including placing a pipe in the well, the lower end of which is installed in the interval of the absorption zone, supplying simultaneously a curable plug composition and gas to the mixing zone associated with the upper end of the pipe, and then injecting the obtained gas-containing mixture into the well through the pipe and placing this mixture in the absorption zone, characterized in that the gas-containing mixture is pumped into the well through a pipe, the lower and upper ends of which have a reduced odnoe section, if the pressure in the absorption zone range location is in the same order with atmospheric or through the tube, the upper end of which has a reduced flow cross-section, if the pressure in the absorption zone arrangement interval commensurate with the pressure in the pipe when injection.
