MEASUREMENT WHILE DRILLING PULSER WITH TURBINE POWER GENERATION UNIT

摘要

Disclosed are a system, device, and method for generating pulse signals t hat correlate to geological information in a wellbore. The system and method comprises a pulse generating device longitudinally and axially positioned w ithin an annular drill collar flow channel such that the drilling fluid flow s through the annular drill collar flow channel and the drilling fluid is gu ided into two sets of selectively reversible flow, upper and lower flow conn ecting channels, wherein the connecting channels are connected to an inner f low channel and the annular drill collar flow channel, and wherein the annul ar drill collar flow channel is acted upon by one or more flow throttling de vices thereby transmitting signals. The device utilizes a turbine residing n ear and within proximity of a flow diverter that diverts drilling mud into a nd away from turbine blades such that the force of the drilling mud causes t he turbine blades and the turbine to rotationally spin around a coil assembl y.
