摘要
抽油机是油田主要耗能设备,因其结构可靠被广泛应用,约占机采设备的65%。目前油田常用抽油机类型主要为常规游梁式抽油机,对于游梁式抽油机的地面部分,影响地面效率的因素主要分为三类:一类为电气部分,即变压器和电动机;第二类为传动部分,主要为皮带、减速箱;第三类为平衡部分,主要是平衡块的调节。根据变压器及电动机的效率曲线,合成电气系统的合理运行区间为负载率在30%以上;分析皮带、减速箱的运行特性,给出皮带调节的合理范围挠度在1.7 cm左右;给出了平衡度的合理调节范围在93%~97%之间。分析抽油机地面效率影响因素及采取相应的对策,这有利于节能减排,减少生产成本,并对油田实际生产有相当重要的现实意义。
Oil pumping unit is the main energy-consuming equipment in oilfield. It is widely used because of its reliable structure and is about 65% of artificial lift equipments. Currently the main types of oil pumping unit used commonly is a conventional beam pumping unit. For the ground part of beam pumping unit, there are three kinds of factors affected the ground efficiency, such as transformer and motor, belt and gear box, balance block adjusting. According to the efficiency curve of transformer and motor, the reasonable running range of electrical system is over 30% of load rate. 1.7 cm deflection can be given by analyzing the characteristics of belt gear box.The reasonable adjusting range for balance block is between 93% and 97%. The energy-saving &consumption-reducing, the production cost-reducing can be realized by studying and analyzing the factors affected the ground efficiency.
