Abstract
Il s'agit d'un générateur d'impulsions rotatif écoénergétique et intelligent qui permet de produire une impulsion dans la boue, dans une application de mesure pendant le forage (MWD). Dans un générateur d'impulsions rotatif, un circuit de commande active un moteur sans balais qui fait tourner un étrangleur à fenêtre par rapport à un boîtier fixe, pour agir comme volet obturateur et fenêtre, respectivement. L'ouverture de l'étrangleur à fenêtre permet généralement l'écoulement libre de la boue. La fermeture de l'étrangleur à fenêtre limite l'écoulement de la boue. L'étrangleur à fenêtre est mû dans les opérations d'ouverture et de fermeture par le moteur.
