| Abstract: | The strap-down automatic vertical drilling system(AVDS) is a new automatic vertical drilling tool for deviation control and fast drilling in precipitous structure area.Under little inclination angle and dynamical rotary conditions,a new inclination and azimuth dynamical measurement algorithm is proposed for strap-down AVDS.Simulated is dynamical algorithm by different inclination angles and rotating velocities,the result of which shows that the calculation values without calibration are close to true azimut... |
