Abstract:
An asynchronous top-mounted pulser system for a measurement while drilling tool uses hydraulic flow, an obstruction, a piston-balance system, and an orifice, to create pressure pulses in drilling fluid, using hydraulic pressure on an obstruction in a main pulser to assist in closing the obstruction. A valve poppet is set above (upstream of) the orifice and is pushed by fluid flow towards a closing position. The piston-balance system, connected to the poppet and located downstream of the orifice in the main pulser, responds to net pressures on the upstream and downstream sides of the piston to move the poppet. The piston also responds to a spring assembly urging the piston downstream, and tending to move the valve poppet to a closed position. A servo pulser, located downstream of the main pulser, opens and closes a rotary shear servo valve-controlled bypass flow path to control the net pressures on the piston.

Claim (Index 34):
A method of transmitting a mud pressure pulse in a pulse telemetry MWD system, comprising:\n pumping drilling fluid downstream to a main pulser,\n said main pulser comprising;\n a main orifice positioned within said pulser; and\n an obstruction movably positioned within said pulser; \n said obstruction being positioned upstream of said orifice; and \n \n a bypass conduit defining a fluid flow path in said main pulser by-passing said orifice;\n said first by-pass conduit having no valve; and \n said first by-pass conduit passing substantially down a center of said orifice; and \n \n \n commanding a servo pulser to operate a servo valve;\n said servo pulser being positioned downstream of said pulser.
