Filed:

Jan 6, 1993

Appl. No.:

8/000989

Inventors:

Roger Chancey - Humble TX
Robert J. Champagne - Lafayette LA

Assignee:

International Drilling Systems, Inc. - Lafayette LA

International Classification:

E21B 402
F16J 1532

US Classification:

175107

Abstract:

An improved mud motor system for drilling or workover down hole which includes an upper stator portion housed within a stator body connectedly engaged to a drill or workover string. The stator receives a flow of drilling mud through the drill or workover string, and flow of mud through a continuous bore of a certain profile within the stator, imparts rotation to the rotor. The lower end of the rotor is engaged to a first upper drive shaft, which is in turn connected to an upper and lower output shaft. Rotation of the rotor likewise imparts rotation to the drive and output shafts. There is provided a drill bit or specialty bit secured to the lower end of the lower output shaft which, when rotation is in effect, drills into the formation or performs various workover operations. There is further provided fluid bearings within the assembly to provide a quantity of fluid to bear against the lower (or upper) output shaft, so that the shaft contacts the fluid bearing when the shaft is forced upward or down depending on the type of operation taking place.
