抽油机智能间抽节能控制系统研究

为稳定产量、降低能耗、提高系统效率和减少抽油机的维修费用，设计了一种抽油机智能间抽节能控制系统，以控制抽油机合理间抽为主要任务，即采用多种传感器采集油井信息，通过微处理器对抽油机井动态供液状况进行判断，同时结合新型的油井生产供排关系理论和液面变化规律，动态的选取抽油机的间抽标准和启停时间，运用对比优化的方法，更加有效地控制抽油机的启停，经过实验测试，达到了节约能源和智能化控制目的。

Research on Intelligent Inter-drilling and Saving Energy Control System of the Beam Pumping Unit

In order to keep production stable, reduce energy consumption, improve the efficiency of the system, and cut down the maintenance cost of the pumping units, an intelligent inter - drilling control system of the pumping unit has been de- signed in this paper. The main task of the system is keeping the inter - drilling rational. It collects oil well information with kinds of sensors, and esti- mates the fluid dynamic conditions of pumping wells by means of the microprocessor. Meanwhile, combining with the latest theory of supply - dis- charge balance of oil well production and the chan- ging rules of liquid level, applying the method of contrast optimization,it can control the stop- start of the pumping unit more effectively than before. Experimental tests have proved that the system meets the goals of saving energy and intelligent control.
