摘要： Downhole tools are provided for measuring the inclination of a portion of a drill string. In certain embodiments, downhole tools for measuring inclination comprise a catch system for measuring inclination and a pressure pulse signaling system for communicating inclination measurement information to the surface. Catch systems for measuring inclination include a series of disc mounted on an upper shaft, each disc having a ball disposed thereon.

摘要： A shock absorber for attachment between a downhole motor and drill bit for drilling a well. Shafts within the tool's housing are supported by radial bearings outside of the shafts, and slideably and rotationally engaged with each other by mating splines. The lower shaft telescopically extends from around the outside of the upper shaft, the extension limited by an upper shaft mandrel ledge against a lower shaft internal shoulder. A biasing mechanism within the shock absorber's housing dampens shock between the motor and bit.

摘要： In one embodiment, a downhole assembly includes a motor that is operatively coupled to a transmission, wherein the transmission is operatively coupled to an upper shaft disposed within a housing. The upper shaft is supported by a first radial bearing assembly disposed within the housing. A thrust bearing assembly including a ball bearing disposed between two races is provided. The upper shaft extends through and is supported by the first radial bearing. A distal end of the upper shaft has a first set of mating splines disposed thereon. A lower shaft supported by a second radial bearing assembly is disposed within the housing, wherein the lower shaft has a second set of mating splines disposed thereon. The second set of mating splines are adapted to mate with the first set of mating splines and the lower shaft is telescopically extendable from the upper shaft. A catch is machined on an internal surface of the lower shaft to limit the extent of travel of the lower shaft. A biasing mechanism is disposed adjacent the ball bearing, wherein the biasing mechanism biases the lower shaft in an extended position with respect to the upper shaft, wherein the biasing mechanism comprises a series of disc springs. A drill bit that is operatively coupled to the lower shaft.
