METHOD AND APPARATUS FOR COLLECTING DRILL BIT PERFORMANCE DATA

摘要

Drill bits and methods for sampling sensor data associated with the state of a drill bit are disclosed. A drill bit (200) for drilling a subterranean formation comprises a bit body (240) and a shank (210). The shank further includes a central bore (280) formed through an inside diameter of the shank and configured for receiving a data analysis module (290). The data analysis module comprises a plurality of sensors, a memory, and a processor (300). The processor is configured for executing computer instructions to collect the sensor data by sampling the plurality of sensors, analyze the sensor data to develop a severity index, compare the sensor data to at least one adaptive threshold, and modify a data sampling mode responsive to the comparison. A method comprises collecting sensor data by sampling a plurality of physical parameters associated with a drill bit state while in various sampling modes and transitioning between those sampling modes.
