The near drill bit instrument is designed to address the limitation of traditional MWD/LWD instruments where the measuring point is too far away from the drill bit.

In traditional downhole drilling tool assemblies, there are components such as motors, stabilizers, and non-magnetic sensors between the drill bit and the MWD/LWD sensor, which extend the distance between the measuring point and the drill bit and cause measurement data delay. In complex formations or thin reservoirs, delay can delay the judgment of the formation, prevent timely adjustment of drilling direction, and cause loss of drilling encounter rate.

The near drill bit instrument moves the measuring point down to the vicinity of the drill bit. The measuring point of GS-ABT is about 30cm away from the drill bit, which can reflect the engineering and geological data of the drill bit position in real time, eliminate hysteresis, and improve the real-time response efficiency of drilling. It is particularly effective for drilling control in thin oil layers and complex formations.

GS-ABT has been used in operations in Xinjiang and Changqing regions, with good operating conditions. The inclination measurement near the drill bit position is accurate and timely, and can match the MWD part of the inclination measurement data; The azimuth gamma data of the drill bit position can also accurately reflect the geological data of that location.

During the operation of Well Quan 131, in addition to completing inclinometer and geological data collection, vibration monitoring and analysis were carried out to provide suggestions for improving the drilling tool assembly for the drilling team. The improved drilling tool assembly improved efficiency and increased footage per unit time.

GS-ABT will accumulate data and optimize through continuous practical operations.
