发明名称 Core barrel holder and methods of using same
摘要 A core barrel holder for supporting a core barrel during removal of a core sample from the core barrel. The core barrel holder includes a housing, an inner sleeve, a plurality of support elements extending radially inwardly within the inner sleeve, a spring, and a cap. Upon positioning of the core barrel holder in an operative position, the inner sleeve receives the core barrel. Upon advancement of the core barrel through the inner sleeve, the plurality of support elements frictionally engage the core barrel within the inner sleeve.

主权项 1. A core barrel holder for supporting a core barrel during removal of a core sample from the core barrel, the core barrel holder having a longitudinal axis, the core barrel holder comprising: a housing having a longitudinal length, a proximal surface, an outer surface, and an inner surface, the housing defining a proximal opening and a distal opening, the inner surface having a proximal portion and a distal landing portion and defining an interior space of the housing; an inner sleeve having a longitudinal length, an outer surface, an inner surface, and a support portion, the inner sleeve defining a proximal opening and a distal opening, the inner surface of the inner sleeve defining an interior space of the inner sleeve, the support portion of the inner sleeve being positioned between the proximal and distal openings of the inner sleeve along the longitudinal length of the inner sleeve, the support portion extending radially outwardly from the outer surface of the inner sleeve relative to the longitudinal axis of the core barrel holder and defining a proximal engagement surface, a distal engagement surface, and a plurality of bores radially spaced about the longitudinal axis of the core barrel holder, each bore of the plurality of bores extending from the inner surface to the outer surface of the inner sleeve; a plurality of support elements, each support element of the plurality of support elements being received within a respective bore of the plurality of bores of the support portion of the inner sleeve such that a portion of the support element projects inwardly from the inner surface of the inner sleeve; a spring having a proximal end and a distal end; and a cap having an inner surface, an outer surface, and a proximal lip portion and defining a proximal opening and a distal opening, the proximal lip portion extending radially inwardly from the inner surface of the cap relative to the longitudinal axis of the core barrel holder, thereby defining an inner engagement surface, wherein, in an operative position of the core barrel holder, the inner sleeve is received through the proximal opening of the housing such that the support portion of the inner sleeve is positioned within the interior space of the housing, the spring is positioned such that the distal end of the spring engages the proximal engagement surface of the support portion of the inner sleeve, the outer surface of the cap engages the proximal portion of the inner surface of the housing, and the inner engagement surface of the lip portion engages the proximal end of the spring, and wherein, in the operative position of the core barrel holder, the proximal opening of the inner sleeve is configured to receive the core barrel, and, upon advancement of the core barrel through the interior space of the inner sleeve relative to the longitudinal axis of the core barrel holder, the distal engagement surface of the support portion of the inner sleeve is configured to engage the distal landing portion of the housing, and the plurality of support elements are configured to frictionally engage the core barrel within the interior space of the inner sleeve.
