Problems solved by technology
At present, oil well production management belongs to extensive management, with oil wells as the smallest unit of energy consumption. How to reduce the energy consumption of each oil well per ton of liquid per day and per ton of liquid lifting has not achieved precise energy efficiency management and precise energy efficiency. Intelligent management, the reason is that the optimization of energy efficiency measures cannot be realized as a technical support, resulting in high operating costs and waste of power energy
Diagnosis and detection of oil wells and optimization and adjustment of operating parameters are seriously delayed. With the operation of oil wells, the operating parameters of oil wells have changed when energy efficiency adjustments are made, and the purpose of immediate adjustment cannot be achieved. The difference is huge, and it is necessary to carry out "one well, one policy" and real-time optimization and adjustment of operating parameters. Only by implementing energy-saving management with fine energy efficiency and intelligent optimization for each oil well can the energy consumption of mechanical oil recovery in the whole country be greatly reduced, and energy saving can be achieved. Substantial breakthrough in energy consumption and energy-saving management level
[0003] The problem to be solved in this patent is: since the production of oil wells is dynamically changing, real-time adjustment of operating parameters cannot be achieved manually, resulting in extremely low efficiency of the pumping unit operating pump, how to improve the operating pump efficiency of the pumping unit of the oil pumping equipment; Since the load sensor is installed in a fixed anti-unlocking method, the on-site operation is extremely inconvenient, which is not conducive to the real-time transmission and parameter correction of real-time parameters. Therefore, the problem to be solved in this patent is how to adjust and improve the original load sensor so that it can To achieve the purpose of real-time parameter transmission and parameter correction

The invention relates to an oil well mechanical production energy efficiency optimization system. According to the system, accurate optimization of energy efficiency is realized in two aspects: coordination intelligence of liquid supply and extraction is realized by identifying the fullness of an indicator diagram and adjusting the rotating speed of an oil pumping unit, and the fullness of a pumpis adjusted and improved at any time; due to reverse elastic deformation of a sucker rod string caused by load switching change at the loading and unloading moments of an upstroke sucker rod and a downstroke sucker rod of the oil pumping unit, accurate low-speed and time length matching is adopted, so that stroke loss is reduced, and effective stroke is increased; a sensor strong magnetic protection plate and a circuit superconducting material antimagnetic box are adopted. The system has the advantages of convenience in installation and maintenance, high compatibility, stable and reliable operation and high energy saving rate. With the system adopted, existing frequency converters can be integrated to control oil well resources; the front-end function of the Internet of Things can be achieved; and production cost can be greatly reduced. The system is a novel and distinctive oil well mechanical production energy efficiency optimization system.

Background technique [0002] Electricity consumption in oilfield production is the first cost of oilfield production, and the power consumption of pumping units is an important part of the cost expenditure. At present, oil well production management belongs to extensive management, with oil wells as the smallest unit of energy consumption. How to reduce the energy consumption of each oil well per ton of liquid per day and per ton of liquid lifting has not achieved precise energy efficiency management and precise energy efficiency. The reason for intelligent management is that the optimization of energy efficiency measure...
