Abstract: Изобретение относится к нефтегазодобывающей промышленности и может быть использовано для отбора газа из затрубного пространства скважины, оборудованной штанговым глубинным насосом. Компрессор к станку-качалке содержит прикрепленные к балансиру станка-качалки и его опоре шарниры цилиндра и штока поршня, трубопровод, связывающий полость цилиндра с затрубным пространством, и отводящий трубопровод с соответствующими всасывающим и нагнетательным клапанами. Цилиндр компрессора частично заполнен снизу маслом, а поршень по периметру герметично взаимодействует с внутренней поверхностью цилиндра с возможностью возвратно-поступательного движения, разделяя цилиндр на верхнюю и нижнюю полости, сообщенные обводным каналом с клапаном, пропускающим в сторону верхней полости. Цилиндр изготовлен дифференциальным, состоящим из нижнего широкого цилиндра с нижней полостью и верхнего узкого цилиндра с верхней полостью. Трубопровод от затрубного пространства скважины сообщен с нижней полостью. Снизу цилиндр снабжен соосной цилиндрической масляной камерой. Поршень сверху соединен со штоком, изготовлен ступенчатым, состоящим из верхней и нижней частей под соответствующие верхний и нижний цилиндры, оснащен снизу цилиндрическим соосным выступом под масляную камеру, с которой взаимодействует при перемещении поршня вниз относительно цилиндра. Поршень оснащен каналом, сообщающим масляную камеру и верхнюю полость цилиндра через клапан, пропускающий масло снизу вверх. Масляная камера сообщена с емкостью, заполненной маслом, через масляный клапан, пропускающий внутрь нижней камеры и настроенный на большее усилие открытие, чем другие клапаны. Обводной канал может быть оснащен охладителем.
