Abstract
Disclosed are a system, device, and method for generating pulse signals that correlate to geological information in a wellbore. The system and method comprises a pulse generating device longitudinally and axially positioned within an annular drill collar flow channel such that the drilling fluid flows through the annular drill collar flow channel and the drilling fluid is guided into two sets of selectively reversible flow, upper and lower flow connecting channels, wherein the connecting channels are connected to an inner flow channel and the annular drill collar flow channel, and wherein the annular drill collar flow channel is acted upon by one or more flow throttling devices thereby transmitting signals. The device utilizes a turbine residing near and within proximity of a flow diverter that diverts drilling mud into and away from turbine blades such that the force of the drilling mud causes the turbine blades and the turbine to rotationally spin around a coil assembly.
