Abstract
Official abstract text for this publication.
A vibratory tool for use in a tubular string to prevent sticking or to release a stuck string features a fluid operated dart valve working in conjunction with an impact sleeve to deliver continuous axial jarring blows in opposed directions as long as flow is maintained. Movement of one of those components axially in opposed directions opens and closes access to opposed lateral ports so that a lateral vibration is also established as flow cyclically occurs and stops sequentially at opposed lateral outlets.
First claim
Opening claim text (preview).
We claim: 1. A vibratory tool for use in a tubular string at a subterranean location and which defines an annular space therearound, comprising: an axial vibration assembly movable in a tubular housing, said axial vibration assembly is continuously operable to create vibrations in an axial direction; said axial vibration assembly having a selectively closable passage therethrough to allow tools to pass until said passage is obstructed with an object to allow said axial vibration…
