The configuration of the present invention is simple, low energy consumption, and mining is high-efficient, the Rodless oil extraction operation suitable for high angle hole, horizontal well.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Oil pipe is shorted 5 hydraulic cylinder of hollow piston rod, 6 piston body 7 in 2 upper sleeve gasket, 3 cylinder barrel top connection 4 on 1
The lower oil pipe of lower 10 lower sleeve gasket of hollow piston rod, the 11 cylinder barrel lower contact 12 in 8 low pressure production fluid flow road 9 of high voltage power liquid channel is short
Connect under 13 hollow draw-bar connector, 14 cylinder barrel annular space on 15 cylinder barrel of annular space.
Specific embodiment
A kind of dedicated underground hydraulic motor that recovers the oil, including hydraulic cylinder 5,5 upper end of hydraulic cylinder are connected by cylinder barrel top connection 3
Tubing nipple is connected, upper oil pipe is shorted 1 for connecting with oil well oil conduit, upper sleeve gasket 2 is arranged at 3 center of cylinder barrel top connection, on
2 upper end of sealing shroud is connect with the concentric little oil pipe lower end of oil well, and the concentric little oil pipe upper end of oil well connects Surface power drive equipment；On cylinder barrel
Production fluid data feedback channel is provided on connector 3 is connected to hydraulic cylinder 5 with upper oil pipe short circuit 1, and 5 lower end of hydraulic cylinder passes through under cylinder barrel
Connector 11 connects lower tubing nipple, and lower oil pipe is shorted 12 and connect with oil pump sleeve, close under being arranged at 11 center of cylinder barrel lower contact
Big envelope 10.
Dual channel plunger is set in cylinder barrel, dual channel plunger include piston body 6, upper hollow piston rod 4 and under hollow work
Stopper rod 9 forms annular space 15 on cylinder barrel above piston body 6, forms annular space 14 under cylinder barrel, upper hollow piston below piston body 6
The diameter of bar 4 is less than the diameter of lower hollow piston rod 9, and piston body 6 is provided with high voltage power liquid channel 7 and low pressure production fluid flow road 8,
7 upper end of high voltage power liquid channel is connected to upper hollow piston rod 4, and upper 4 top of hollow piston rod is located in upper sleeve gasket 2, and low pressure produces
