The invention relates to a technical production of oil, in particular to a plunger lift, such as its plunger,

rn s

It can be used in oil and gas pipes. Immersed in water, the temperature of the existing industry for which increases with increasing liquid from the oil and the depth of plunger immersion.

the rod 10 begins to extend, while its free end is 15 from 10

:, .-.,: air wells.

The purpose of the invention is to increase the efficiency of the work.

Fig. I shows a plunger for an unger: a first elevator, a general view; FIG. 2 is a section A-A in FIG.

Plunger for plunger lift socks with hollow expansion chamber 1; | ..; him 2 and lower 3 bottoms and pa-. -:,;: channels 4, sealing - element 5, mounted on the outer housing 1, forming the

The cement 16 moves along the screw groove 13 of the channel 12 of the hub 11, turning the flaps 9 at a certain angle (with two dampers, they turn 90) and closing off the valve 8 at 15 the bottom 3 of the housing 1. After that, the gas entering the well begins to lift the plunger while water, being above it, flows through the radial channels 4 into the hermetic i 7: plenum chamber 6, communicating with the 20 camera 6 and stretches the sealing v body of the housing 1 through its radial element 5, pressing it against the walls: 4 channels 4. The plunger is equipped with elevator pipes, no leakage tolerance

House 7, in the bottom bottom of the cylindrical raised volume of water, temperature-cus 1 is filled with windows 8 and in which it practically does not decrease.

The inner flap 9 is located on the inner side, the kine-rod is 25. At the same time, the rod 10 is not compressed and mathematically associated with the actuator 7 and the valve 9 reliably overlap the windows

installed with the possibility of overlap - 8 bottom bottoms 3. of windows B.

The actuator 7 is made in the form of a rod. At the wellhead, it is lifted in 10 and is connected to the lower day, 30 and is poured into the discharge line (3) with a hub 11 with channel 12 and is shown), the temperature around the ram groove 13, one end of the shaft rod 14 is lowered and the rod 10 is compressed, while the flaps 9 open the windows 8 of the lower bottom 3, and the seal is rigidly connected to the upper body 2 of the hollow cylindrical body I, and

The trigger 1 and its outer diameter decrease. The pressure below and above the plunger is released, and the plunger falls down again. The cycle of pumping water from well 40 is repeated.

Claims (1)

Invention Formula its other free end. 15 supplying the body element 5 is pressed against the spline flange m. 16, which is installed with the possibility of interaction with the screw groove 13 of the hub 11, on which the shutters 9 are fixed. The linear expansion coefficient of the material of the rod 10 is larger than linear expansion coefficient of the body material -1. The rod 10 is mounted in a protective housing 17 and is associated with the housing 1 super-1. Plunger for plunger lift, Xy through the struts 18 of the upper bottom 45 containing a cylindrical housing with upper and lower bottoms and radial channels, a sealing element mounted on the outer surface of the housing with the formation gg of an airtight chamber communicating with the cavity of the housing through its radial channels different from that that in order to increase efficiency 20 and below through struts 19. The shutters 9 are fastened to the hub 11, which is installed in the center of the bottom plate 3 of the housing 1 on the support 20. The plunger works as follows. During the descent of the plunger into the lift pipes (not marked), it moves downward under the force of gravity, it is equipped with a drive, and at the bottom, the rod 10 of the drive 7 is compressed so that 55 the bottom of the cylindrical body has its windows 15 The center of the rasp is at the extreme upper position and the dampers are blocked, kinematically, the links 9 do not overlap the windows 8 sealed with the drive and mounted with the tel element 5 due to their elasticity with the possibility of blocking the windows. Guest are pressed against the outer walls of the housing 1. All this allowed the plunger is free to move down the elevator The trigger 1 and its outer diameter decrease. The pressure below and above the plunger is released, and the plunger falls down again. The cycle of pumping water from the well is repeated. Invention Formula body element 5 is pressed against the core 2, POP-1 plunger, characterized in that the drive is made in the form of a rod and provided with a hub with a channel and a screw groove connected to the bottom head, one end of the rod is rigidly connected to the top bottom of the hollow cylindrical body, and the other has a slot. installed with the possibility of interaction with the screw groove of the hub on which the dampers are fixed, while the linear expansion coefficient of the rod material is larger than the linear expansion coefficient of the material of the body.
