抽油机控制技术与电动机合理匹配研究

Reasonable Matching Research of Oil Pumping Control Technology and Motor

为进一步控制配电系统投资,降低机采系统运行能耗,找到电动机与抽油机控制技术的最优组合形式,采用现场测试不同组合形式能耗,对比投资回收期、功率因数及现场应用情况的方法,对抽油机控制技术与电动机的合理匹配进行了研究。结果表明:单速电动机+控制装置A的组合形式投资回收期短,功率因数高,现场操作方便,功能实用,因此将其确定为最优组合形式。这种组合形式提高了配电系统适应性,可作为指导采油工程方案设计的理论依据。依据分析结果,在产能建设区块应用329口井,年可节电934.7×104k Wh,年可节省电费626.3万元。

In order to further control the power distribution system investment, reduce the energy consumption of machine mining system operation, find the most optimal combination of motors and oil pumping control technology, this paper adopts the method of field test different combination forms of energy consumption, compares the investment payback period, power factor and field application to study reasonable matching of oil pumping control technology and motor. The results show that investment payback period of the combined form of single speed motor plus control device A is short, power factor is high, site operation is convenient, function is practical. So this combination is identified as optimal combination forms. This combination improves the adaptability of the distribution system,and it can be used as the theoretical basis for guiding the design of oil project. According to the analysis results,329 wells were applied in the production capacity building block and annual power saving is 934.7×104 k Wh, annual electricity cost saving can be 6.263 million yuan.
