摘要
常规抽油机的冲程长度、冲次不能实时改变,因而地面装备与井下抽油泵的工况不可能达到最佳配合状态,致使抽油泵的泵效低、冲击载荷大、能耗高。地面抽油装备采用数控变频调速技术,其冲程长度、冲次在规定参数范围内可以任意调节,并可随井下工况的变化而实时变化,能使抽油机-抽油泵系统处于最佳协调状态,达到降低能耗、提高采收率的效果。
This article describes a new pumping unit with digital control, on which the frequency conversion speed regulation technology is used. The stroke length and the stroke per minute of the described pumping unit can be easily adjusted according to the working condition of the subsurface pump, thereby the subsurface pump system can be operated in optimum conditions and the energy consumption-can be reduced and the oil recovery can be enhanced.
