摘要： A mud pulser system for use in a wellbore includes a pulser assembly disposed in a drill string and through which drilling fluid is metered in order to generate pressure pulses in the drilling fluid. The pulser assembly includes a pulser body having an inlet and an exit. Included in the pulser body is a rotary member having multiple ports formed through the member. The rotary member can be spherically shaped. The ports are formed so that selectively rotating the rotary member registers opposing ends of a one of the ports with the inlet and exit in the body to provide communication between the inlet and exit. An actuator couples with the rotary member for its selective rotation.

摘要： A steerable earth boring assembly which includes an annular collar and a drive shaft with a drill bit, where the shaft pivots with respect to the collar. An upper portion of the shaft inserts into an orientation sleeve which resides in the collar. An axial bore is obliquely formed through the orientation sleeve, and in which the upper portion inserts. An angular offset between the drive shaft and collar is changed by adjusting azimuthal positions of the orientation sleeve with respect to the collar. A brake assembly is included for applying a restraining force onto the orientation sleeve.
