详细介绍了C－D井在钻进过程中井眼轨迹的控制过程，总结了在C－D井中使用导向钻井系统的成功经验。用1根导向马达、2套钻具组合、3只牙轮钻头顺利地完成了定向、增斜、稳斜及降斜，7个目标点一次击中，且最小靶心距仅0．99m。用15d完成了这口斜深2287．09m、井斜58．40°、水平位移903．11m的多目标定向井，钻穿目标点之多、实钻井眼剖面符合率之高、施工难度之大、速度之快，在目前国内都处于领先地位。
The control process of well trajectory in C-D well during drilling is introduced in detail, and the successful experience of using guided drilling system in C-D well is summarized. With one steering motor, two sets of drilling tools and three roller bits, the orientation, incline, stability and descent were successfully completed. Seven target points were hit at one time, and the minimum target distance was only 0.99m. The multi-target directional well with a depth of 2287.09m, a deviation of 58.40 ° and a horizontal displacement of 903.11m was completed in 15 days. As many drilling targets were drilled, the coincidence rate of the actual borehole profile was high and the construction difficulty was large , The speed is fast, in the current domestic are in a leading position.
