Selectively actuated vibrating apparatus connected with well bore member

摘要: A vibrating apparatus connected with a member insertable into well bore including an and retrievable enabling the to be selectively actuated. The includes rotatable, eccentric weight forming rotor having closable through passage means bypass oriented impart rotation of when is closed pressurized fluid required pass for discharge in offset relation axis rotating thereby which it attached. In one embodiment invention, by ball valve can inserted flow at ground surface movement engagement seat gravity together magnet retrieving subject magnetic attraction. Another plug spiral passageway peripherally thereof being locked rotatable provided communicating guiding pressure therethrough. third involves construction drillable material enable effectively used running casings or like.
