Summary of the invention
The utility model provides a kind of Oil/gas Well twin-well ground mining device, and it can utilize sucker rod to decline and the energy of generation, reduces the waste of energy.
A kind of 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.
The utility model has the advantages that: 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.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model;
Detailed description of the invention
A kind of Oil/gas Well twin-well ground mining device, comprises the lifting gear 3 that can automatically realize the motor 1 of rotating and be driven by motor 1; It also comprises for a well oil cylinder 4 of mining a well liquid, a well sucker rod 8, and for b well oil cylinder 5, the b well sucker rod 9 of mining b well liquid; In described a well oil cylinder 4 and b well oil cylinder 5, be respectively arranged with a well piston 6 and b well piston 7; The top of described a well sucker rod 8 is connected with a well piston 6 through the lower cylinder of a well oil cylinder 4 of sealing, and the top of described b well sucker rod 9 is connected with b well piston 7 through the lower cylinder of the b well oil cylinder 5 of sealing; The top of described a well piston 6 is connected with lifting gear 3, and described lifting gear 3 can drive a well piston 6 to pump at vertical direction; The lower cylinder of described a well oil cylinder 4 and b well oil cylinder 5 is filled with respectively fluid; Between described a well oil cylinder 4 and b well oil cylinder 5, be provided with the connecting pipe 10 that can make two fluid in oil cylinder be communicated with.
Described lifting gear 3 is screw body.
Described motor 1 drives lifting gear 3 by deceleration device 2.
In the time that a well sucker rod 8 of a well oil cylinder 4 moves downward, the fluid in a well oil cylinder 4 flows in b well oil cylinder 5 by connecting pipe 10, promotes the fluid column of b well oil cylinder 5.In the time that a well sucker rod 8 of a well oil cylinder 4 moves upward, the b well sucker rod 9 of b well oil cylinder 5, due to down motion under Action of Gravity Field, makes the fluid in b well oil cylinder 5 flow in a well oil cylinder 4 by connecting pipe 10, promotes a well sucker rod 8 and moves upward.
