| Abstract: | The mechanical model of the drilling tool assembly with single centralizer is introduced, and the calculation method of theory build-up rate of the bending screw drill is illustrated. Fur- thermore,Many factors are synthetically analyzed, which have a great influence on the build-up rate of the bending screw drill with centralizer,and the methods of borehole trajectory control. This method of borehole trajectory control is successfully applied to the design of two testing screw drill and has directive significance in the on-site technical service work. |
