A method and apparatus for protecting a sensor from impact and abrasion while drilling a borehole including a drill collar having a section of electrically non-conductive material, such as a composite material. The electrically non-conductive material has a rugged structural strength for conveying required drilling operation torque and load. The sensor which, for example, induces an RF field, is located inside the drill collar within the section of electrically non-conductive material wherein the sensor is protected from impact and abrasion while drilling a borehole without interference to the electromagnetic energy. The sensor is located, for example, within a load bearing section of the drill collar. Alternatively, the sensor is located inside a removable probe positioned inside the fluid channel through the drill collar.

L'invention porte sur un procédé et un dispositif permettant de protéger un capteur des chocs et de l'abrasion lors d'un forage. Ce dispositif comprend une masse-tige pourvue d'une section de matériau sans conduction électrique tel qu'un matériau composite. Le matériau non conducteur possède une extraordinaire résistance structurale lui permettant de véhiculer la charge et le couple de forage nécessaires. Le capteur pouvant induire, par exemple, un champ HF, est placé à l'intérieur de la masse-tige dans la section de matériau non conducteur et est protégé des chocs et de l'abrasion lors du forage sans interférence sur l'énergie électromagnétique. Le capteur peut aussi être placé dans une section de support de charge de la masse-tige. Dans une autre variante, le capteur est placé à l'intérieur d'une sonde amovible positionnée dans le canal fluidique traversant la masse-tige.
