【Abstract】 The well trajectory controlling principles and modes for modulated rotary steering drilling system were researched. According to the deviation between the actual well trajectory and the planned one, the well trajectory controlling method and the corresponding algorithm were determined. By using the algorithm for generating control commands, a downhole tool manipulated on the surface was designed to meet the requirements of the well trajectory control technology. The software of the surface monitoring and control system was developed. The design and implementation of the well trajectory control program were especially introduced.更多还原
