Title (EN) NON-MAGNETIC SURVEY INSTRUMENT FOR BOREHOLES, CASINGS OR DRILL STRINGS
(FR) INSTRUMENT POUR RELEVÉ NON MAGNÉTIQUE POUR TROUS DE FORAGE, TUBAGES OU TRAINS DE TIGES
Abstract:
(EN) Non-magnetic survey instrument (100) for borehole, casing or drill string formed by a body (110) accommodating centralizer assemblies (120-122) and measuring systems (170-190), the non-magnetic survey instrument (100) being arranged for continuous surveying as the non-magnetic survey instrument (100) travels downwards or upwards in a borehole, casing or drill string.
(FR) L'invention concerne un instrument pour relevé non magnétique (100) pour trou de forage, tubage ou train de tiges formé d'un corps (110) logeant des ensembles centreurs (120-122) et des systèmes de mesure (170-190), l'instrument de sondage non magnétique (100) étant conçu pour un relevé continu lorsque l'instrument de relevé non magnétique (100) se déplace vers le bas ou vers le haut dans un trou de forage, un tubage ou un train de tiges de forage.
