Abstract

The invention belongs to an energy-saving type submersible progressive cavity pump oil production system used in the petroleum drilling and production industry. The system is characterized in that a submersible motor is arranged above a tubing anchor, and a motor protector, a speed reducer oil tank, a submersible speed reducer, a speed reducer protector, a lower suspension, a suction device, a screw pump, a suspension connecting device, a desilting unloading uniflow device, an oil conveying pipe, a liquid level monitoring device and a remote intelligent monitoring system are sequentially arranged above the submersible motor. The energy-saving type submersible progressive cavity pump oil production system is stable and reliable in work, remarkable in economic benefit, capable of being widely applied to oil wells under various work conditions for oil production, particularly suitable for inclined wells and horizontal wells, and particularly remarkable in offshore oil production.

Description

Technical field: [0001] The invention belongs to an energy-saving submersible screw pump oil extraction system used in the oil drilling industry, in particular to an electromechanical device integrating machinery and electrical control for oil extraction and coal field drainage and gas extraction. Background technique: [0002] The current submersible screw pump oil production is not perfect, and it can work continuously for up to 6 months. Equipment failures occur in mechanical parts, such as protectors, submersible reducers, suspension connection devices, etc., which reduces the utilization rate of equipment and has Reduced production efficiency. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming, and provide a kind of energy-saving submersible screw pump oil recovery system that works stably, reliably and economically. [0004] The technical solution to be solved by the present invention is: an energy-saving ...
