摘要：A wireline or drill pipe retrievable coring tool with an inner barrel to receive a core, a bottom coring tool valve operable to al off a bottom of the inner barrel and at least one pressure canister operable to receive fluid from the core in the inner barrel. The pressure canister is operable to significantly reduce the pressure inside the inner barrel utilizing an expandable chamber to receive fluid from the core as the tool is removed from the wellbore. In one embodiment, a bottom valve mechanism moves the cored formation materials out of the way of the bottom valve before the bottom valve is clod.
