摘　　要：旋转尾管能解决斜井和水平井尾管难下到位的问题。活动套管固井以提高固井质量的观点,已形成了普遍的共识,对于套管直接到井口的井比较容易实现,但对于尾管而言,悬挂器坐挂后就不能转动,但使用可旋转尾管悬挂器就能解决这一问题。文章介绍了旋转尾管固井技术的发展、旋转尾管固井技术的优点和所需条件及其操作特点。The rotating liner can solve the problem that the liner can’t be run in desired location in deflecting wells and horizontal wells. Moving casing can improve the cement quality. It is easier to achieve for a well in which casing hangs up to the well head, but for liner, the liner hanger can’t be rotated after hanging. But we can solve the problem by using rotating liner hanger. The text introduces briefly the development, advantages and operation characteristics of rotating liner cementing technique.
