SYSTEMS AND METHODS FOR AUTOMATIC DRILLING OF WELLBORES

摘要

SYSTEMS AND METHODS FOR AUTOMATIC DRILLING OF WELLBORES The invention provides a system for automatic control of the drilling an oil well. The system includes an autodrilling interface 50 enabling parameter input data to be input and enabling the display of system output data, a controller 52, a hydraulic control system 54 and at least one sensor configured to the hydraulic control system 54. The controller 52 receives parameter input data from the autodrilling interface 50 and at least one sensor and provides output instructions to the hydraulic control system 54 such that the hydraulic control system 54 operates to control drilling based on controller instructions and sensor data.
