Description
Technical field
the present invention relates to a kind of ground mining device of oil gas field oil well.
Background technology
traditional well recovery machine drives the work of lever reciprocating tractive sucker rod by motor by rocker-arm link.The mechanical energy of exporting by motor rises to certain height by sucker rod, and then sucker rod declines under the effect of self gravitation.In this course, by sucker rod, declined and the kinetic energy that produces is not utilized, caused the waste of energy.
Summary of the invention
The invention provides a kind of Oil/gas Well twin-well ground mining device, it can utilize sucker rod to decline and the energy of generation, reduces the waste of energy.
An Oil/gas Well twin-well ground mining device, comprises and can automatically realize the motor of rotating and by motor-driven lifting gear; It also comprises for a well oil cylinder of mining a well liquid, a well sucker rod, and for b well oil cylinder, the b well sucker rod of mining b well liquid; In described a well oil cylinder and b well oil cylinder, be respectively arranged with a well piston and b well piston; The top of described a well sucker rod is connected with a well piston through the lower cylinder of a well oil cylinder of sealing, and the top of described b well sucker rod is connected with b well piston through the lower cylinder of the b well oil cylinder of sealing; The top of described a well piston is connected with lifting gear, and described lifting gear can drive a well piston to pump at vertical direction; The lower cylinder of described a well oil cylinder and b well oil cylinder is filled with respectively fluid; Between described a well oil cylinder and b well oil cylinder, be provided with the connecting pipe that can make two fluid in oil cylinder be communicated with.
Described lifting gear is screw body.
Described motor drives lifting gear by deceleration device.
Advantage of the present invention is: the energy that a well sucker rod is moved downward to generation promotes the fluid column of b well oil cylinder by hydraulic power, and then the kinetic energy that b well sucker rod is moved downward by hydraulic power for promoting the fluid column of a well, saved energy.
