抽油机是把地层中的石油提升到地面时所必需的一种机器设备,也就是人们俗称为“磕头机”的开采设备。“磕头机”这一俗称生动形象的描绘出抽油机的工作形式,它是通过“磕头”这一动作加压从而使石油出井。抽油机由机械设备和电气两大部分构成。其中,机械设备主要是由减速器、皮带、驴头钢丝绳等构成;电气主要是由控制系统和电机构成。随着抽油机在我国各大油田的普及,人们对抽油机的节电、节能的要求越来越高。笔者通过对我国各大油田进行了走访调查,对抽油机节电控制技术在各大油田的应用有了进一步的了解认识。
The pumping unit is a kind of machinery and equipment necessary for lifting the oil in the formation to the ground, that is, mining equipment commonly known as “kowtow machine”. “Kowtow ” This commonly known as the vivid image depicts the working form of the pumping unit, it is through “kowtow ” This action is pressurized so that the oil out of the well. Pumping unit consists of two parts of mechanical equipment and electrical composition. Among them, the mechanical equipment is mainly composed of reducer, belt, donkey head wire rope, etc .; electrical is mainly composed of the control system and the motor. With the popularization of pumping units in all major oil fields in China, people are demanding more energy-saving and energy-saving pumping units. Through surveying and surveying major oilfields in our country, the author has got a better understanding of the application of energy-saving control technology of pumping units in major fields.
