摘要
在分析了水平井井眼轨迹控制的技术特征的基础上,结合塔里木盆地塔河油田AT1-2H水平井、AT1-9H水平井,从水平井井身剖面优化设计、定向侧钻钻具组合选择、着陆控制技术(包括工具造斜率的确定原则、闭合方位控制技术、稳斜探顶、矢量进靶)、水平控制技术(包括加强复合钻进、垂向控制留有余地、动态监控)等几方面对水平井井眼轨迹控制关键技术进行了深入探讨。
Base on analysing the technique characters of horizontal well bore trajectory control, and integrate the AT1--2H horizontal well, AT1 -- 9H horizontal well where are in Tahe oilfield Talimu basin. This article ingoing research into Gordian techniques of horizontal well bore trajectory control. There Gordian techniques include how to optimise horizontal well bore profile, how to select sidetrack drilling tool assembly, landing control（the principle of tool＇s built-up rates, the technique of closure Azimuth control, drilling the top of the oil layer by maintain angle and how to drill the vectored targets）and horizontal control （adding composite drillings, how to control vertical displacement and dynamic control）.
