| Abstract: | The accomplishments in controlled directional drilling having been made since 1980's are introduced. The practical examples of the single drill hole, multi-h ole drilling, cluster drill and butt drill engineering indicate that the control led directional drilling can not only enlarge the mineral reserves and speed up the exploration, but also reduce the footage and cost. Meanwhile, the mechanical continuous whipstock, hydraulic auger and their structures and functions are de tailed. Finally, the prospect and advantages of controlled directional drilling technology are described. |
