Title: Detecteur pour le radiocarottage avec une interface optique de decouplage
Inventor: DAYTON RODERICK R
IPC: E21B47/01
Filed: 1989-10-20
Abstract: Un détecteur pour le radiocarottage conforme à l'invention comprend un cristal allongé pour scintillation 30 comportant une extrémité déviée contre et optiquement couplée à une partie 14 à fenêtre transparente du logement 12 du détecteur. La force de déviation est générée par un ressort 68 pressant l'autre extrémité du cristal. Elle est suffisamment faible pour permettre au cristal de s'éloigner et d'être désaccouplé optiquement de la partie à fenêtre, en réponse à des forces de choc sur le détecteur. A la suite du désaccouplement, le ressort ramène le cristal contre ladite partie pour rétablir le couplage optique entre eux. Le détecteur est particulièrement bien adapté aux applications aux mesures durant le forage.
