| Abstract: | According to the normal well path types of the directional and sidetrack wells, the calculating process is analyzed and the application cases are given. The theoretical and field applications show that the directional well path derived from this optimum method has the following characteristics: its depth is minimized, its trajectory is smooth and the frictional drag is small. Therefore, it is an optimum scheme to increase penetration rate and decrease drilling cost. |
