Measurement and Control of the Deviation Thrust Correction In Vertical Drilling System

The deviation thrust correcting measurement and control is a pivotal technology in automatic vertical drilling system.An elementary correcting deviation principle of automatic vertical drilling system is briefly described.The circuits of measurement and control system are designed with digital signal controller for the deviation thrust correcting,the thrust is tested at different ambient temperature and environmental pressures,and the interpretation of test data is made.The result shows that the correcting deviation control system is able to meet vertical drilling system for correcting deviation control requirements.
