摘　　要：经对244.47mm套管内用大钻头直接扫水泥悬空塞弊端剖析,得出在244.47mm套管内应用两次管柱扫水泥悬空塞的工艺技术优势,即应用钻塞管柱钻塞时,水泥钻屑量少,且可反循环洗井,大块钻屑可靠自重沉降,为今后大套管试油井扫水泥悬空塞提供了新的解决方案。To analyze shortage of sweeping cement dangling plug testing in 244.47 mm cased well with big bit, it is concluded that the technology of using two times of string to do it has much advantages, during drilling plug, are having less cement scraps and being reverse circulated making big drilling scraps to fall down for their weights that provides a new solution to sweep cement dangling plug testing in big cased well for the future.
