近年来 ,美国石油机械制造商为推动有杆泵抽油系统的技术进步做了大量的工作 ,推出了一系列新技术和装备 ,其中包括Jackshaft减速器、连续油管抽油系统、可消除污染的盘根盒、旋转抽油杆接箍和刚性抽油杆接箍、抗冲蚀泵和多相泵、可在矿场安装的抽油杆导向器 /刮蜡器、可控制抽油机的变频驱动装置、油田自动化软件、测力计系统和电效率测试技术。对以上技术装备分别做了简要介绍 ,并给出了部分装备的结构和性能特点。 In recent years, a great deal of work has been done by U.S. petroleum machinery manufacturers to promote the technological advancement of sucker rod pumping systems. A series of new technologies and equipment have been introduced, including the Jackshaft reducer and coiled tubing pumping system to eliminate contamination Packing boxes, swivel sucker rod couplings and rigid sucker rod couplings, erosion pumps and multiphase pumps, sucker rod guides / scrapers for installation in the mine, variable frequency control of the pumping unit Drive, field automation software, dynamometer systems and electrical efficiency testing techniques. The above technical equipment were briefly introduced, and gives the structure and performance characteristics of some of the equipment.
