Measurement while drilling pulser with turbine power generation unit

A method for generating pressure pulses in a drilling fluid, flowing within a drill string, comprising:

• a pulse generating device longitudinally and axially positioned within an annular drill collar flow channel such that said drilling fluid flows through said annular drill collar flow channel and said drilling fluid is guided into two sets of selectively reversible flow, upper and lower flow connecting channels, wherein said connecting channels are connected to an inner flow channel and said annular drill collar flow channel, and wherein said annular drill collar flow channel is acted upon by one or more flow throttling devices thereby transmitting signals, and generating pulses via a pilot actuator assembly including a pilot, a pilot bellows, a pilot seat, a pilot seat orifice, flow throttling device(s), a sliding pressure chamber, and a pulser guide pole, wherein said upper and lower inner flow connecting channels provide for reversal of flow and wherein said pilot seals a middle inner flow channel from said lower inner flow channel and such that said flow throttling device(s) and said pilot are capable of bi-directional axial movement along or within said guide pole and said device utilizes a turbine residing near and within proximity of a flow diverter that diverts drilling mud in said annular flow channel into and away from turbine blades such that the force of the drilling mud causes said turbine blades and said turbine to rotationally spin around a coil assembly wherein said coil assembly that generates electrical power for operating a motor and other operating equipment wherein said motor comprises a drive shaft centrally located between said motor and a magnetic pressure coupling wherein said motor and said coupling are mechanically coupled such that said motor rotates said magnetic pressure coupling outer magnets and moves said pilot actuator assembly wherein said magnetic coupling is formed by a location external and internal to a magnetic pressure cup where outer magnets are placed in proper relation to inner magnets, said inner magnets located in a position inside said magnetic pressure cup, said coupling allowing for translating rotational motion of said motor and said outer magnets into linear motion of said inner magnets via a magnetic polar interaction, wherein linear motion of said inner magnets move said pilot actuator assembly by linearly moving said pilot into said pilot seat, closing said pilot seat orifice, lifting said flow throttling device(s) into a flow throttling orifice and thereby generating a pulse wherein further rotation of said motor drive shaft and said outer magnets move said pilot actuator assembly and said pilot away from said pilot seat causing said flow throttling device(s) to move away from said flow throttling orifice, thereby generating another pulse.
