Скважинный гидродомкрат относится к нефтяной и газовой промышленности и может быть использован при установке в стволе скважины устройств, требующих больших осевых усилий. Для повышения надежности и долговечности силового устройства в скважинном гидродомкрате, в каждом из последовательно соединенных силовых блоков, поршень соединен со штоком с возможностью радиального перемещения относительно корпуса гидроцилиндра; кроме того, поршень по периметру снабжен полостью, заполненной антикоррозионной смазкой, контактирующей с внутренней поверхностью гидроцилиндра и гидравлически связанной с областью высокого давления. Такое конструктивное решение позволяет снизить трение в сальниковых узлах, в результате чего повышается КПД устройства.Well hydraulic jack refers to the oil and gas industry and can be used when installing in the wellbore devices that require large axial forces. To increase the reliability and durability of the power device in the borehole hydraulic jack, in each of the series-connected power units, the piston is connected with the rod with the possibility of radial movement relative to the hydraulic cylinder body; in addition, the piston around the perimeter is provided with a cavity filled with anticorrosive lubricant in contact with the inner surface of the hydraulic cylinder and hydraulically connected with the high pressure area. Such a constructive solution allows to reduce friction in the packing units, as a result of which the efficiency of the device is increased.
