대우대사도정화대위이정，채용표부하투관기술가이유효강저하투관적난도，강저투관우조적풍험。본문개소료재BZ34-1-D8h정응용표부접고순리장투관하도위적성공안례，위대위이정작업제공차감。
Floating casing technologies as applied in highly-deviated and large-displacement wells, can effectively reduce the difficulty of casing and the risk of blocked. This paper introduces the successful application of floating collar in BZ34-1-D8h well for casing, and provide reference for large displacement wells operation.
