| 摘 要： | 套管漂浮技术主要应用于大位移延伸井和水平井中,它是在套管柱下部封闭一段空气或低密度钻井液,使套管柱在大井斜段处于漂浮状态,以降低下套管摩阻。主要介绍了套管漂浮工具的结构和工作原理以及漂浮技术在国内几个海洋油田钻大位移延伸井和水平井中的应用情况。

| Abstract: | The casing floating technology is used chiefly in extended reach wells and horizontal wells. That is a section of air or light density drilling fluid holded inside lower casing string to keep casing string floating in section of high deviation well to decrease drag running casing. This article introduces mainly construction of casing floating tool and working theory and floating technology used in extended reach wells and horizontal wells in several national offshore oil fields. |

| Keywords: | offshore drilling equipment high angle deviated well horizontal well casing floating pipe joint technology |
