摘　　要：PDC钻头在胜利油田桩西地区的成功应用 ,大大地提高了该地区的机械钻速。但由于PDC钻头在结构与钻进参数上的特殊性 ,造成了其在定向井中井眼轨迹控制方面的难度。本文总结了PDC钻头在桩西地区定向井中应用所表现出的部分规律 ,提出了在该地区采用PDC钻头的改进技术 。The drilling speed in zhuangxi oilfield has been raised significantly by using PDC bit. But the particularity of drilling parameter and character of PDC bits add to difficulties of controling hole trajectory in directional well. The rules are discussed of using PDC bit in directional well in zhuangxi. The improving measures are put forward, and field application status is introduced.
