Novel oil well pump for oil exploitation

Abstract

The invention discloses a novel oil well pump for oil exploitation. The novel oil well pump structurally comprises a pumping pipe, a pumping wire wrapping rod, a pumping pulling rope, pulleys, pulley shaft levers, pulley assembly heads, a pulley supporting rod, a pumping stress device, a permanent magnet attraction plate, a permanent magnet switch, an electromagnetic connecting wire, an electromagnet, a pumping filter head, oil pumping feed chutes and an oil pumping filter screen. The pulley supporting rod is cuboid-shaped, and the top of the pulley supporting rod is vertically locked to the pulley assembly heads. The pulley assembly heads are cuboid-shaped, the pulleys are embedded and fastened to middle portions of left and right sides of inner ends of the pulley assembly heads via the pulley shaft levers, and the pulleys are also embedded and fastened to upper sides of middle portions of the inner ends of the pulley assembly heads via the pulley shaft levers. When the device is used, a power source can be automatically recovered when attraction of the device is disconnected through a spring, pumping recovery can be more easy, the device can be well ensured to continue oil pumping, pumping recovery speed can be reduced by the pumping pipe of the device through a pumping telescopic pipe, and piston damage caused by fast recovery can be well prevented.

Description

technical field [0001] The invention is a novel oil well pump for oil exploitation, which belongs to the field of oil well pumps. Background technique [0002] The oil pump is a common downhole device driven by the pumping unit to pump the crude oil in the well to the surface. Ordinary oil well pump is mainly composed of four parts: pump barrel, suction valve, piston and discharge valve. According to the fixing method of the oil pump in the well, it can be divided into tube pump and rod pump. [0003] 1. Tubular pumps: Tubular pumps are also called tubing pumps, which are characterized in that the outer cylinder, bushing and suction valve are assembled on the ground and connected to the lower part of the tubing and lowered into the well first, and then the piston equipped with the discharge valve is used to pump oil. The rod is lowered into the pump through the tubing. [0004] The bushing is machined into several sections from the material and lined inside the outer cyli...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a new type of oil well pump for oil exploitation, so as to solve the problem that when the existing technology is used, it is easy to be unable to drag the pumping motor due to insufficient force of the oil pumping back pressure. As a result, the oil pump will not be able to automatically return pressure, which will cause the equipment to fail to guarantee continuous oil pumping, causing inconvenience in use
