Abstract
Способ откачки газа из отключенного участка газопровода, включающий подачу газа в сопло газового эжектора и перекачку этим газовым эжектором газа из отключенного участка газопровода в параллельную нитку или в участок, следующий за отключенным участком, отличающийся тем, что к отключенному участку газопровода дополнительно подключают жидкостно-газовый эжектор, сопло которого сообщено с гидронасосом, а выход из жидкостно-газового эжектора через сепаратор сообщают с параллельной ниткой газопровода или с участком газопровода, следующим за отключенным участком, при этом вход в гидронасос сообщают с емкостью с жидкостью, размещенной под сепаратором, после чего по мере уменьшения интенсивности откачки отключают газовый эжектор, и производят откачку газа из отключенного участка газопровода жидкостно-газовым эжектором, включив подачу жидкости на его сопло.A method of pumping gas from a disconnected section of a gas pipeline, including supplying gas to a nozzle of a gas ejector and pumping gas from a disconnected section of a gas pipeline to a parallel string or to a section following a disconnected section, characterized in that a liquid-gas additionally is connected to the disconnected section of the pipeline an ejector whose nozzle is in communication with the hydraulic pump, and the outlet of the liquid-gas ejector through the separator is communicated with a parallel line of the gas pipeline or with a section of the gas pipeline, as follows behind the disconnected section, while the entrance to the hydraulic pump is communicated with a liquid container located under the separator, after which, as the pumping intensity decreases, the gas ejector is turned off and gas is pumped out of the disconnected section of the pipeline by the liquid-gas ejector, turning on the liquid supply to its nozzle.
