SYSTEM AND METHOD OF DRILL PIPE ACCOUNTING Russian patent published in 2017 - IPC E21B47/04 E21B47/09 E21B19/10 

Abstract RU 2618242 C2

FIELD: machine building.

SUBSTANCE: invention relates to the integration of state of round-trip operations, in particular to accounting of drill pipes. The method of a drill pipe accounting includes detecting whether the drill string is lowered through the rig floor, and monitoring movement of the draw works which supports the drill bit and drill pipe length. If the device does not detect query tag wireless tags associated with a set of wedge grips, the method includes counting draw works movement to account drill pipes. If the tag query device detects the wireless tag associated with a set of wedge grips, the method includes the lack of consideration of the movement of draw works to account drill pipes. The mark request device is positioned in a fixed layout relative to the rig floor.

EFFECT: invention provides an error or misstatement in the calculations.
