Embodiment Construction

[0013] The intelligent hydraulic oil production well device of the present invention is composed of a hydraulic pump 1 and its hydraulic conduit 2 connected to a piston oil pump 3 under the oil production well shaft 4 . The hydraulic conduits 2 of the hydraulic pump 1 are two alternately pressurized conduits that enter the oil production wellbore 4 and are connected to the downhole piston oil pump 3, and the other constant-pressure pressurized conduit 5 is connected to the well sealing device 6 under the wellbore. The well sealing device 6 is connected and fixed with the piston oil well pump 3 as a whole. A channel 29 and a one-way valve 30 are provided in the sealing device 6 to connect the lower shaft 4 and the upper shaft 4 of the sealing device 6 in one direction.

[0014] The intelligent hydraulic oil production well device of the present invention has a driving piston 8 in the hydraulic cylinder 7 of the piston oil pump 3, and the driving piston 8 is fixedly connected wi...

Abstract

The intelligent hydraulic oil extraction well device comprises a hydraulic pump and a piston oil-well pump under the oil extraction well case connected with the hydraulic conduit. Two alternative pressurizing hydraulic pipes of the hydraulic pump stick into the oil-well case and connect with a piston oil extraction pump; a constant pressurizing pipe connects with a well sealer that combines with the piston oil extraction pump under the well case. Inside the hydraulic cylinder of the said piston oil extraction pump, there is a drive piston that combines with an oil extraction piston inside of the oil extraction pump cylinder. A hydraulic pipe joins a pump head hydraulic joint, which connects with the drive piston's bottom cavity inside the hydraulic cylinder through a pressure transmission pipe. And the hydraulic joint connects with the drive piston's upper cavity inside the hydraulic cylinder through a pressure transmission groove, and joins another hydraulic pipe. Reasonable in design, simple in structure, reliable in mechanical performance, low in deficiency rate, small in size and land occupation, it is energy saving, safe, high efficient, low in cost with high productivity and stable production.

Description

technical field [0001] The invention belongs to an oil production device, in particular to an intelligent hydraulic oil production well device. Background technique [0002] The traditional oil pumping unit is composed of a motor driving a lever through a rocker arm connecting rod to reciprocate and pull the sucker rod, commonly known as a kowtow machine. The equipment is widely used in the field of oil recovery, and its technology is mature. Its mechanism and principle have basically remained unchanged for a long time. This is incompatible with the current development of electromechanical technology and the development of new high-tech technologies that are widely used today, and its shortcomings have gradually emerged, such as the existing mechanical equipment is very large, high cost, high failure rate, energy consumption Big wait. Contents of the invention [0003] The invention aims at overcoming the deficiencies of the prior art, and provides an intelligent hydraul...
