Abstract
Изобретение относится к нефтяной промышленности, а именно к скважинным штанговым насосам, используемым при добыче нефти. Задачей изобретения является предотвращение утечки жидкости и попадания механических частиц в зазор между плунжером и цилиндром путём создания стабильной эмульсии в пескопроявляющих скважинах, эксплуатирующихся скважинными штанговыми насосами. Поставленная задача решается тем, что скважинный штанговый насос содержит цилиндр с всасывающим клапаном и размещенный в нем с зазором полый плунжер с нагнетательным клапаном, сверху на плунжер ввинчен ниппель и на корпусе ниппеля по поперечному сечению под углом 120° выполнены три резьбовых канала, направленные в сторону движения перекачиваемой жидкости и образующие с осью ниппеля угол 15-20°.The invention relates to the oil industry, namely to sucker rod pumps used in oil production. The objective of the invention is to prevent fluid leakage and the ingress of mechanical particles into the gap between the plunger and the cylinder by creating a stable emulsion in sand-producing wells operated by sucker rod pumps. The problem is solved by the fact that the downhole sucker rod pump contains a cylinder with a suction valve and a hollow plunger with a discharge valve placed in it with a gap, a nipple is screwed onto the plunger on top of the plunger, and three threaded channels are made on the nipple body along the cross section at an angle of 120 °, directed to the side movement of the pumped liquid and forming an angle of 15-20 ° with the axis of the nipple.
