US Patent:

43708145, Feb 1, 1983

Filed:

Jul 18, 1980

Appl. No.:

6/170048

Inventors:

William T. Carpenter - Houston TX

International Classification:

E21B 4722

US Classification:

33307

Abstract:

A well tool for detecting well bore deviation which includes a tool adapted to be connected between adjacent components of a drill string, including a longitudinal opening through which drilling fluid can be circulated. At least one vent hole is located in the tool wall for communicating the longitudinal opening with the space outside the tool through which drilling fluid is circulated back to the surface, the vent hole being selectively blocked and unblocked. The angle the tool has deviated from vertical is measured and the vent is unblocked at a time interval after weight is placed on the bit which is determined by the amount of deviation of the tool, the unblocking of the vent causing a pressure drop in the drilling fluid in the tool the timing of which indicates the amount of deviation.

Abstract:

The present invention discloses methods and apparatus for utilizing a downhole electric motor or motors for drilling in a well casing using a combination retrieval/electric conduit cable capable of reliability supplying sufficient electric power to drive the electric motor(s) and other components or a separate retrieval cable and electric conduit where the electrical conduit in attached to or disposed in the casing pipe wall. The electric motors may be combined with mud motors. The casing may be a combination drill pipe/casing in which the combination drill/casing pipes is rotated to rotate the drill bits, preferable in combination with downhole drive motors.
