本文针对常规抽油机能耗高、系统效率低的问题,从实际出发结合油田需要,阐述了对节能抽油机选型的再认识。一是在理论研究和现场调查分析的基础上,突破了在选择抽油机额定载荷时相关参数的瓶颈,使抽油机额定载荷更接近实际需要,从而提高系统效率2.5个百分点。 Aiming at the problems of high energy consumption and low system efficiency of conventional pumping unit, this paper elaborates the re-recognition of energy-saving pumping unit selection based on the actual needs of the field. First, on the basis of theoretical research and on-site investigation and analysis, the bottleneck of the relevant parameters in selecting the rated load of the pumping unit has been broken, so that the rated load of the pumping unit closer to the actual needs, thereby increasing the system efficiency of 2.5 percentage points.
