Abstract

The core barrel apparatus comprises inner and outer core barrels. The upper portion 48 of the outer core barrel is adapted to be connected to a drill string. A core bit 66 for cutting a core sample is mounted on the lower portion 46 of the outer core barrel. The inner core barrel 78 comprises a sample chamber 84 for receiving a core sample as it is formed at the bottom of a bore hole and an expansion chamber 80 for receiving sample fluids. The lower portion of the sample chamber adjacent the core bit is sealed by a flap-valve 90 which includes a flexible flap member. Once the core sample is cut and is within the sample chamber 84, the flap member seals off the chamber. Thereafter the expansion chamber 80 is opened to the sample chamber. As the apparatus is raised toward the surface and the pressure within the bore hole decreases, the expansion chamber 80 expands in response to the pressure of the fluid within it and thereby maintains the pressure within the expansion chamber at or relatively near the bore hole pressure. <IMAGE>
