Abstract

The invention relates to pumping unit intelligent multiplier controller. It mainly includes light and strong current parts. Its feature is that dynamic liquid level transducer and polished rod load and displacement transducer are connected with the CPU to realize exact closed-loop control for the pumping well. The light current part includes main control CUP and controlled CPU; the strong current part includes energy feedback, stand by power frequency, and power frequency conversion interlocking parts. The invention can increase pumping well system efficiency, realize its energy saving and consumption reducing, increase both production and income, input-output ratio, and economic benefit, can be suited for oil field electric network specificity and pumping well variability.

Description

Technical field [0001] The invention relates to an intelligent synergistic controller for pumping units, which is a high-performance industrial control device combining optomechanical and electronic information, and is mainly used in the intelligent synergistic control of oil production by pumping units in oil fields. Background technique [0002] At present, most oil fields in China are in the middle stage of exploitation, and certain technologies of secondary and tertiary oil recovery have great disadvantages, either destructive to the oil quality of the oil layer, or causing pollution themselves, which do not meet environmental protection requirements, that is to say Caused over-exploitation or eagerness for success. In fact, according to the laws of nature, certain oil wells can achieve good recovery effects through reasonable parameter adjustment and optimized management of ground control equipment, so that the system is always in the best operating state, and the optim...
