这里介绍的是美国公司研制应用的4种新型泵抽系统。(1)用于有杆泵抽油的Rotaflex长冲程系统。Rotaflex是用于有杆泵抽油的长冲程抽油系统。该系统应用成熟技术和革新设计,为深井、问题井和高产井开采提供了较高的生产效率和成本效益。一旦需要,配有该系统的有杆泵就可替代电潜泵或井下水力活塞泵。该大型装置的泵冲程长度达366in。其主要优点包括:
Here are four new pumping systems developed and applied by US companies. (1) Rotaflex Long Stroke System for Sucker Rod Pumping. Rotaflex is a long-stroke pumping system for sucker rod pumps. The system uses proven technologies and innovative designs that provide high productivity and cost-effectiveness for deep wells, problem wells and high-production wells. Once required, the rod pump with this system can replace the electric submersible pump or downhole hydraulic piston pump. The pump stroke of this large unit is 366 inches in length. Its main advantages include:
