中文摘要:针对深孔钻探中钻孔弯曲问题，研制了半周期自修正防弯钻具（XBZX）。该钻具采用杠杆工作原理，结构简单。经过多个钻孔应用实践证明，使用该钻具能有效降低钻孔弯曲，并且在许多造斜地层的钻孔施工中取得了良好效果。

Development and Application of Half-period Self-correction Deviation Prevention Drilling Tool
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.
