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.
L'invention porte sur un système, un dispositif et une méthode de production de signaux d'impulsions qui se corrèlent avec des informations géologiques dans un forage. Le système et la méthode comprennent un dispositif générateur d'impulsions placé longitudinalement et axialement dans le canal annulaire d'écoulement du collier de forage traversé par le flux de fluide de forage guidé dans deux ensembles de canaux de liaison de flux sélectivement réversibles, supérieur et inférieur. Lesdits canaux de liaison sont connectés à un canal de flux intérieur et au canal annulaire d'écoulement du collier de forage lequel est actionné par un ou plusieurs dispositifs étrangleurs de flux émettant ainsi les signaux. Le dispositif utilise une turbine proche d'un déviateur de flux qui détourne la boue de forage sur les pales de la turbine pour que la force de la boue entraîne la turbine autour d'un ensemble de bobines.
