Blue Ice Drill （BID）是由威斯康星大学麦迪逊分校冰钻设计与操作小组设计的大直径敏捷钻井系统，用于快速清洁近地表241 mm直径的冰样品。它由一个井下电机/齿轮减速器组成，旋转取心刀和外桶内的取心桶，以有效地在固体冰中输送岩屑。变频驱动器和定制控制箱调节钻机的电力。扭矩反应是通过连接在扭力杆上的手柄在表面完成的。岩心恢复可以通过探空仪中的岩心狗或单独的岩心恢复工具来实现。所有井下工具都通过绞盘绞车上的绳索悬挂在一个可折叠的三脚架上。BID至少由两个人操作，并已成功地在南极洲泰勒冰川的蓝色冰区进行了两个季节的岩心采集。钻井系统的更新版本BID-Deep设计用于回收深度达200米的岩心。
Abstract The Blue Ice Drill (BID) is a large-diameter agile drill system designed by the Ice Drilling Design and Operations group of the University of Wisconsin–Madison to quickly core-clean 241 mm diameter ice samples from near-surface sites. It consists of a down-hole motor/gear reducer rotating a coring cutter and core barrel inside an outer barrel for efficient cuttings transport in solid ice. A variable-frequency drive and custom control box regulates electrical power to the drill. Torque reaction is accomplished on the surface via handles attached to a torsion stem. Core recovery is achieved with either core dogs in the sonde or with a separate core recovery tool. All down-hole tools are suspended on a collapsible tripod via ropes running on a capstan winch. The BID is operated by a minimum of two people and has been used successfully during two seasons of coring on a blue ice area of Taylor Glacier, Antarctica. An updated version of the drill system, BID-Deep, has been designed to recover cores to depths up to 200 m.
