    摘要: A method for drill pipe tallying includes detecting that a drill bit has tripped in through a rig floor and monitoring movement of a drawworks that supports the drill bit and a length of drill pipe. If a tag interrogating device does not detect a wireless tag associated with a set of slips, the method includes counting the movement of the drawworks toward a drill pipe tally. If a tag interrogating device detects a wireless tag associated with a set of slips, the method includes not counting the movement of the drawworks toward the drill pipe tally. The tag interrogating device is positioned at a fixed location relative to the rig floor.
