本文分两部分，此部分讨论了电潜泵的新发展。包括螺杆泵电机及电缆、穿线法兰、传感器和驱动器。同时介绍了气举方面的新技术，如地面电控气举阀、可收回式阀门和气举滑阀、偏心升举塞以及改进气举密封柱塞。同时也介绍了高排量注水工作筒、注水阀、净油计量仪、价格便宜的井下存储仪、井下油、水分离装置和一种新式激光涂层工艺等。下期连载第二部分，介绍螺杆泵采油的新发展。 This article is divided into two parts, this part discusses the new development of ESP. Includes screw pump motors and cables, threading flanges, sensors and actuators. Also introduced airlift aspects of the new technologies, such as ground-controlled gas lift valve, retractable valve and gas lift slide valve, eccentric lift plug and improve gas lift seal plunger. At the same time also introduced the high-displacement water injection tube, water valve, net oil meter, low-cost underground storage, downhole oil, water separation device and a new laser coating process. The second part of the next serial, describes the new development of screw pump oil production.
