ABSTRACT:
[A method and at least one mechanism for carrying out the method is disclosed. A method of (1) generating time modulated torque pulses by engaging and disengaging a mud turbine driven rotating torque generator in the bottom of a wellbore, and (2) monitoring the top of the drill string for the torque pulses therein may be practiced by a mud driven turbine inertial wheel for being momentarily and precisely braked or decelerated relative to a drill collar on the lower end of a drill string in a wellbore while drilling for generating the time modulated torque pulses in the drill string for being monitored at the surface. Mechanical, electrical, and fluid operated brakes and a mud turbine driven motor are disclosed for providing power to a motor at the bottom of the drill string or for being intermittently braked rapidly for generating the torque pulses.]
Methods and apparatuses for driving a means, as a power generator in a drill string while drilling, in a well are disclosed. One method comprises (1) circulating drilling mud internally of the drill string, (2) rotating a turbine in the drill string with the circulating drilling mud, (3) driving the power generator in the drill string with the mud driven turbine, and (4) powering a modulated torque pulse generator control system with the power generator for generating modulated torque pulses in the drill string. A transmission system for driving a modulated pulse generator means while drilling comprises (1) mud driven turbine means including a cylindrically shaped turbine having inwardly extending vanes for receiving and having drilling mud circulating therethrough, and (2) the mud driven cylindrical turbine means being responsive to the circulating drilling mud for powering the modulated pulse generator means while drilling.
