Description

Известные устройства дл  пропуска полированного штока внутрь подъемных труб не защищают его от вредного действи  коррозии и абразива.The known devices for passing the polished stem into the lifting tubes do not protect it from the harmful effects of corrosion and abrasive.

Предлагаемое устройство не имеет этого недостатка, так как сальник выполнен с .плотно насаженным патрубком, заполненным чистой нефтью, газом или другим веществом.The proposed device does not have this drawback, since the epiploon is made with a tightly fitted branch pipe filled with pure oil, gas or another substance.

На чертеже показано предлагаемое устройство применительно к гидравлическим станкам-качалкам в трех вариантах исполнени .The drawing shows the proposed device as applied to hydraulic pumping units in three versions.

В первом варианте исполнени  (позици  а) внутри насосных труб 7 помещаетс  патрубок 2 в виде трубы, внутри которого перемещаетс  полированный щток 5, соединенный со щтангами 4. В верхней части патрубка смонтирован сальник 5, а насосные трубы переход т в выкидную линию 6. Полированный щток соедин етс  с порщнем 7 цилиндра 8 гидропорщиевого двигател .In the first embodiment (position a) inside the pump tubes 7 a pipe 2 is placed in the form of a pipe, inside which a polished brush 5 is moved, connected to the shafts 4. A gasket 5 is mounted in the upper part of the pipe and the pump pipes are transferred to the flow line 6. Polished the brush is connected to the piston 7 of the cylinder 8 of the hydraulic piston engine.

В процессе откачки пластовой жидкости содержащиес  в ней нефть и газ за счет разницы в удельном весе заполн т внутреннюю полость патрубка и тем самым изолируют щток и уплотнение от контакта с пластовой жидкостью, содержащей активные коррозионные воды и песок.In the process of pumping out the formation fluid, the oil and gas contained in it, due to the difference in specific gravity, fills the internal cavity of the branch pipe and thereby isolates the brush and seal from contact with the formation fluid containing active corrosive waters and sand.

Патрубок может быть также заполнен смазкой, имеющей здельный вес меньще удельного веса добываемой жидкости.The nozzle may also be filled with a lubricant having a gross weight less than the specific gravity of the produced fluid.

Во втором варианте исполнени  (позици  б) патрубок непосредственно соединен с цилиндром гидропорщневого двигател , что позвол ет упростить установку за счет исключени  сальника.In the second embodiment (item b), the nozzle is directly connected to the cylinder of a hydraulic piston engine, which allows to simplify installation by eliminating the stuffing box.

В третьем варианте исполнени  протектора, предназначенного дл  гидропривода с утопленным (подвижным цилиндром, защита полированного щтока производитс  по приведенной на чертеже (позици  в схеме.In the third embodiment of the tread designed for a hydraulic drive with a recessed (movable cylinder, the protection of the polished brush is made as shown in the drawing (position in the diagram.
