摘　　要：为了达到液控智能井在需要检泵或出现控制管线拔断等故障需要维修时,不用将井下工具全部提出的目的,研制了一种适合于油、气、水开采的智能井井下对接工具。该工具包括留井对接总成和留井密封总成,通过该工具将井下生产管柱分离,并进行快速准确地对接。对接采用棘爪分瓣式螺纹结构,对接强度高,对接方便、可靠;采用球阀关闭原理,保证6个传压通道同时处于密封状态。实验室的测试结果表明,该工具具有非常可靠的密封能力,能够满足深海智能井的开采要求。智能井井下对接工具的研制有利于智能井技术的大面积推广。To avoid tripping out all the downhole tools during pump inspection or workover due to break of control line in hydraulic control intelligent completion well,a downhole docking tool for intelligent completed oil,gas and water wells has been developed. The tool,including a letting-in docking assembly and a letting-in seal assembly,is used to detach and quickly and accurately dock the downhole production tubing string. The pawl joint with threaded structure ensures a high strength,convenient and reliable docking. The ball valve close principle ensures simultaneous sealing state of the six pressure transmission channels. Laboratory test results indicate that the tool could meet the requirements of deep water intelligent completion wells with great sealing capability.
