title = "Redundant method for measuring downhole posture of the steering drilling tool",
abstract = "Exact downhole posture measurement of steering drilling tool can provide reliable control parameters for downhole control system, so as to ensure the accurate control of hole trajectory. How to ensure the reliability of the posture measurement system while it works in harsh environment is a key technique in the engineering process of steering drilling system. A redundant measurement method based on multi-accelerometers has been put forward according to the analysis of the working environment and measurement reliability requirements of posture measurement system. Then the posture parameter solution formulas were given. According to the linear relationship between measurement signals, a reconfiguration method of the redundant measurement system was put forward to ensure the fault-tolerant operation of the system.",
