angle holding 定向钻进的人工造斜孔段完成之后，使钻孔仍然保持该造斜结果继续钻进的过程。 稳斜的实质是保直，即采用特定的工艺技术措施使钻孔保持直线轨迹，按造斜后的方位和顶角钻至终孔或因工艺需要稳斜至下一次再造斜。
大斜度井可供选择的下泵位置有在垂直段安装，在造斜段安装、在稳斜段安装、在分支鼠洞井眼安装。
Well intervals where lift pumps can be located in highly deviated Wells include vertical interval, deflecting interval, Angle maintaining interval and branch rat hole.
