An electromagnetic borehole telemetry system providing improved signal to noise ratio is showned in Figure 1. Adaptive filters (28) use noise channels as references to remove noise form the signal channel. Improved sensors (40) provide noise channels with reduced signal content. The motion sensors (42) are shielded from electromagnetic signals to prevent detection of the telemetry signal.

L'invention concerne un système de télémesure électromagnétique de trou de forage présentant un rapport signal/bruit amélioré, comme cela est indiqué à la figure 1. Des filtres adaptatifs (28) utilisent les canaux de bruit comme références pour la suppression du bruit dans les canaux de transmission des signaux. Des capteurs améliorés (40) fournissent aux canaux de transmission des signaux un contenu de bruit réduit. Les détecteurs de mouvement (42) du système sont protégés contre les signaux électromagnétiques, ce qui permet d'éviter toute détection des signaux de télémesure.
