Abstract
A vibration system for drill bit housing and method is disclosed, which may be utilized to assist in lowering a drill string into a wellbore through which drilling fluid is pumped. In one embodiment, a drill bit housing contains a symmetrical rotatable member positioned to rotate in response to drilling fluid pumped through the housing, whereby a mechanical interconnection connected to the rotatable member produces vibrations within the drill bit housing for advancing bottom hole assemblies.
Claims19
A vibration system for use with a drill bit attached to tubular string in a well bore through which drilling fluid is pumped, comprising:
- a drill bit housing;
- drill bit cutters secured to said drill bit housing;
- a symmetrical rotatable member positioned within said drill bit housing to rotate in response to drilling fluid flow through said drill bit housing;
- and
- a mechanical interconnection to said rotatable member whereby said rotatable member and said mechanical interconnection operate to produce vibrations within said drill bit housing.
A vibration system for use with a drill bit attached to tubular string in a well bore through which drilling fluid is pumped, comprising:
- a drill bit housing;
- drill bit cutters secured to said drill bit housing;
- a reciprocating member mounted in said drill bit housing operable for reciprocating in response to fluid flow through said drill bit housing for producing vibrations.
A method for a drill bit attached to tubular string in a well bore through which drilling fluid is pumped, comprising:
- providing a tubular drill bit housing;
- providing that drill bit cutters are secured to said tubular drill bit housing;
- mounting a symmetrical rotatable member within said drill bit housing to rotate around an axis substantially in line with an axis of said tubular drill bit housing is attached in response to drilling fluid flow through said drill bit housing for producing a gyroscopic effect in said drill bit housing.
