摘要
电动潜油螺杆泵作为一种新型的无杆采油设备 ,它在高粘度稠油、高含砂、高含气和斜井的原油开采中具有独特的优势。它从根本上解决了有杆泵在稠油开采中的抽油杆断脱以及在深井、斜井中应用时杆管偏磨等问题 ,具有检泵周期长、泵效高、能耗低等优点。在介绍了电动潜油螺杆泵的结构组成、工作原理及技术参数和性能特点后 ,详述了在稠油、斜井、高含砂等疑难井开采中的现场应用情况 ,并做了经济效益分析。建议要进一步提高减速器的承载能力 ,研制大排量高扬程螺杆泵 。
After an introduction of the design feature and operating principle and performance characteristics of electric submersible screw pumps, its application in problem wells, such as viscous oil wells, deviated wells and sandy wells, is described, and an economic analyzed is made. It is suggested that large-displacement screw pump with high lift be developed to widen its application scope.
