Abstract
Скважинное устройство для перепуска затрубного газа, расположенное в колонне насосно-компрессорных труб с муфтой и содержащее обратный клапан и радиальный гидравлический канал, отличающееся тем, что радиальный гидравлический канал расположен в нижней части муфты и связан с одной стороны с затрубным пространством скважины через обратный клапан, а с другой стороны - с полостью НКТ через струйный аппарат, причем оси радиального гидравлического канала и струйного аппарата пересекаются в области сопла последнего; кроме того, устройство содержит отклонитель газожидкостного потока, выполненный в виде втулки и с возможностью фиксации в муфте колонны НКТ, а длина отклонителя потока меньше расстояния между приемом и выкидом струйного аппарата, при этом муфта НКТ имеет внутренний паз, а отклонитель газо-жидкостного потока - кольцевой держатель, при том оси радиального гидравлического канала и струйного аппарата перпендикулярны.A downhole annular gas bypass device located in a tubing string with a coupling and comprising a check valve and a radial hydraulic channel, characterized in that the radial hydraulic channel is located at the bottom of the coupling and is connected on one side to the annulus of the well through a check valve, and on the other hand, with the tubing cavity through the jet apparatus, the axes of the radial hydraulic channel and the jet apparatus intersect in the nozzle region of the latter; in addition, the device contains a gas-liquid flow deflector made in the form of a sleeve and with the possibility of fixing in the tubing string coupling, and the length of the flow deflector is less than the distance between the intake and discharge of the jet apparatus, while the tubing coupling has an internal groove, and the gas-liquid flow deflector an annular holder, while the axes of the radial hydraulic channel and the jet apparatus are perpendicular.
