An inner core barrel assembly incorporates an inner core tube. A body is connected to the inner core tube with a coupling mechanism. The coupling mechanism is configured to maintain a fixed rotational orientation with the inner core tube. The body includes a flow path for liquid within the inner core tube to flow as the inner core barrel assembly descends through a drill string. a core orientation system is contained within the body and positioned within the inner core tube.

Check valve, associated downhole data collection system and inner core

A check valve may be incorporated in an inner core barrel assembly. The check valve has a valve body defining a fluid flow path and provided with a valve seat. A valve member is located in the valve body and is coupled to the valve body by a coupling mechanism. The coupling mechanism is arranged to allow the valve member to move linearly in an axial direction relative to the valve body on to and off of the valve seat and maintain a fixed rotational relationship with the valve body. A data acquisition system can be held in the valve member and by virtue of the coupling mechanism be maintained rotationally fixed relative to the valve body an inner core tube of an inner core barrel assembly.
