Abstract: To addressthe issue of insuficient measurement accuracy in downhole measurement-while-driling(MWD) accelerometers,this paper proposed an online compensation method for MWD accelerometers based on the Magnetic-Inertial Honey Badger Algorithm (MIHBA). Firstly,an error compensation model was established by analyzing the characteristics of MWD accelerometers,with error parameters formulated as a solution vector. Secondly,leveraging the constant magnitude of gravitational acceleration and its direction,a target function for accelerometer errors was designed. Error constraint conditions were established based on the relationship between MWD gyroscope,accelerometer,and magnetometer outputs. The MIHBA was developed from the Honey Badger Algorithm (HBA),incorporating initial values derived from historical accelerometerdata and processed outcomes.During the exploration phase,a trust-region mutation strategy was introduced to enhance population diversity,considering the recursive relationships among MEMS sensors. In the exploitation phase,reflection operations inspired by nonlinear simplex methods were applied to poorly adapted individuals,improving convergence precision. Vibration table tests and actual driling experiments demonstrate that the MIHBA-compensated borehole inclination error accuracy improves by approximately 64.8% ,with the error magnitude maintained within 1.43∘ . The algorithm effectively removes noise from magnetometer signals,significantly enhancing the overallaccuracy of MWD accelerometer measurements.
