Abstract
A core sampling apparatus includes an inner tube configured to collect a core sample by means of a core catcher attached to one end of the core sampling apparatus, and an outer tube co-axially disposed on the outside of the inner tube, wherein the inner tube includes a plurality of impregnation windows configured to allow resin to flow into the core sample, each window including a window opening and a window cover configured to cover the window opening. A method for sampling a core includes extracting a core sample using a core sampler, transporting the inner tube containing the core sample to the surface, impregnating the core sample with a resin by allowing the resin to flow into the core sample through a plurality of impregnation windows formed on the inner tube, and allowing for the resin to cure, thereby stabilizing unconsolidated sediment in the core sample.
