    • In an injector head (30) for handling tubing for insertion into and retrieval from a wellbore, a non-gripping portion of the path (22) of each chain loop (12), which is otherwise susceptible to oscillations when running in at least certain conditions, is constrained by a chain guide (44). The chain guide allows the chain to move freely as it is driven by the sprockets (16) in a loop, but dampens or prevents development of oscillations in the chain loop (12) when moving along one or more sections of its path in which it is not otherwise be pressed against tubing or constrained by sprockets or tensioners.
    • 在用于处理用于插入井眼和从井筒中取出的管道的喷射器头部(30)中,每个链环路(12)的路径(22)的非抓握部分,否则当至少一定行驶时易于振荡 条件受链条引导件(44)约束。 链条引导件允许链条在由链轮(16)以环路驱动时自由移动,但是当其沿着其路径的一个或多个部分移动时,阻止或阻止链环(12)中的振荡的展开, 没有其他方式被压在管道上或受链轮或张紧器约束。
