| Abstract: | Half-period self-correction deviation prevention drilling tool is developed aiming at the borehole deviation in deep hole drilling, which has simple structure based on level principle. It has been proved by the application in several boreholes that this drilling tool can effectively reduce the boreholes bending; and good results have been achieved in many easily inclined formations drilling construction. |
