Abstract
L'invention concerne un tube carottier pouvant être connecté à un train de tiges pour récupérer un échantillon carotté comprenant des solides et des fluides. Selon l'invention il comprend une première chambre 84 ayant une ouverture pour recevoir l'échantillon; un moyen 90, 91 pour sceller sélectivement l'ouverture de la chambre après réception d'un échantillon carotté; une seconde chambre dilatable et fermée 80 adjacente à la première pour recevoir les fluides de l'échantillon, l'extérieur de la seconde chambre quand il est disposé dans un sondage étant exposé aux conditions ambiantes de ce sondage; et un moyen 182, 184 pour connecter sélectivement les deux chambres et permettre aux fluides d'entrer dans la seconde; et un moyen pour actionner à distance le moyen de connexion. L'invention s'applique notamment à l'étude des couches souterraines.A core barrel connectable to a drill string for recovering a core sample comprising solids and fluids is disclosed. According to the invention it comprises a first chamber 84 having an opening for receiving the sample; means 90, 91 for selectively sealing the opening of the chamber after receiving a cored sample; a second expandable and closed chamber 80 adjacent to the first for receiving sample fluids, the exterior of the second chamber when disposed in a borehole being exposed to the ambient conditions of that borehole; and means 182, 184 for selectively connecting the two chambers and allowing fluids to enter the second; and a means for remotely actuating the connection means. The invention applies in particular to the study of underground layers.
