A vibrating apparatus connected with a member insertable into a well bore including an insertable and retrievable member enabling the vibrating apparatus to be selectively actuated. The vibrating apparatus includes a rotatable, eccentric weight forming a rotor having selectively closable through passage means and bypass means oriented to impart rotation of the eccentric weight when the through passage is closed and pressurized fluid is required to pass through the bypass for discharge in offset relation to the axis of rotation for rotating the eccentric weight thereby vibrating the apparatus and the well bore member to which it is attached. In one embodiment of the invention, the through passage is closed by a ball valve which can be inserted into the flow passage at ground surface for movement into engagement with a valve seat by gravity together with a magnet insertable into the flow passage for retrieving the ball valve which is subject to magnetic attraction. Another embodiment of the vibrating apparatus includes an insertable plug having a spiral passageway peripherally thereof with the plug being locked to the rotatable eccentric weight when inserted into the flow passage and provided with a passageway communicating with the spiral passageway for guiding fluid pressure therethrough. A third embodiment involves the construction of the vibrating apparatus of drillable material to enable it to be effectively used when running in well casings or the like.
In combination with a member inserted into a well bore, a vibrating apparatus connectable to said member to impart lateral vibratory movement thereto for loosening the member in the well bore, said vibratory apparatus comprising a housing having means at the lower end for connection to the member and means at the upper end for connection with a source of pressurized fluid, said housing having a hollow interior communicating with the ends of the housing, an eccentric rotor rotatably journaled in said housing and having a center of mass offset from the axis of rotation, said rotor including a passageway extending therethrough for communication with the upper and lower ends of the housing, said passageway being coincident with the rotational axis of the rotor whereby passage of fluid therethrough will not rotate the rotor means associated with said passageway to selectively prevent downward fluid flow therethrough and bypass passageway means providing communication past said means when the means is closed, said bypass passageway means including reaction means through which pressurized fluid passes to impart rotary movement to the eccentric rotor and cause the housing and member to vibrate when pressurized fluid flows downwardly through the bypass passageway means and is discharged from the housing into a low pressure zone in the well bore.
In combination, a well bore having a tubular member therein normally receiving a flow of fluid under pressure and subjected to being undesirably jammed in the well bore, a vibrating apparatus connected to said member and forming a portion of the fluid flow path whereby fluid flow through the member in the well may be maintained, said vibrating apparatus including a housing connected into the tubular member, an eccentric rotor mounted in the housing and including a through passage for flow of fluid under pressure with the through passage being concentric with the rotational axis of the rotor whereby flow through the rotor will not cause rotation thereof, and bypass passageway means associated with the rotor and being in communication with the through passage through the rotor, means for selectively causing fluid flow under pressure through the bypass passageway means, said bypass passageway means including a discharge disposed laterally of and in angular relation to the rotational axis of the rotor whereby discharge of fluid under pressure from the bypass passageway means will exert rotational torque on the rotor for causing rotation of the rotor and vibration of the housing and member to which it is connected thereby loosening the member in the event of an undesirable jam of the member within the well.
