国内外斜井举升工艺现状
THE PRESENT SITUATION OF LIFTING TECHNOLOGY FOR DEVIATED WELL AT HOME AND ABROAD
-
摘要: 随着石油工业的发展,国内外出现了越来越多的斜井、定向井采油技术,因此调研有杆泵、电潜泵、水力喷射泵、水力活塞泵及气举这五大类举升工艺在斜井中的应用和发展具有十分重要的意义。Abstract: The deviated and directional wellsare more and more at home and abroad with the development of petroleum industry.Therefore,it has important significance to investigate the applications and development of the sucker red pump,electrical submersible pump,hydraulic piston pump,hydraulic jet pump and gas lift to deviated wells.
