Title
(EN) DOWNHOLE CORE SAMPLING AND TESTING APPARATUS
(FR) DISPOSITIF POUR ECHANTILLONNER ET TESTER LA CAROTTE DE FOND
Abstract
(EN) A coring apparatus permitting taking of a non-rotating core sample and testing of same, as by NMR, prior to breakage and ejection from the apparatus. A core barrel is suspended from a rotating outer sleeve by one or more bearing assemblies which permit the core barrel to remain stationary during rotation of the sleeve with attached core bit for cutting the core. A core test device is fixed with respect to the core barrel on the outside thereof, to test the core as it proceeds through the barrel. The apparatus optionally includes a directional detecting device such as an inclinometer, and a compact set of circumferentially-spaced steering arms for changing the direction of the apparatus during coring.
(FR) Dispositif de carottage permettant de prélever un échantillon de carotte non rotatif et de le tester, par exemple par RMN, avant de le casser et de l'éjecter du dispositif. Un carottier est supporté par un manchon externe rotatif au moyen d'un ou de plusieurs ensembles supports qui lui permettent de rester stationnaire durant la rotation du manchon portant la couronne de carottage, de façon à couper la carotte. Un dispositif d'essai de la carotte, fixé à l'extérieur du carottier, permet de tester la carotte pendant qu'elle passe à travers le carottier. Le dispositif comprend éventuellement un système de détection directionnelle tel qu'un inclinomètre, ainsi qu'un ensemble compact de bras de direction disposés circonférentiellement, qui permettent de modifier la direction du dispositif durant le carottage.
