摘　　要：在理论分析与现场实践的基础上 ,认为单弯组合并不会导致井眼严重扩大 ,并给出了导致井眼扩大的条件。介绍了单弯滑动导向钻井的主要技术措施 ,以及保证井下安全。Based on the theoretical analysis and field applications, it is considered that single bend assembly will not cause serious hole enlargement. The conditions resulting in hole enlargement are also given. The main technical measures are introduced in steering drilling by using single bend sliding tools, as well as some technical measures to ensure downhole safety and to improve penetration rate.
