Abstract:
A centrifuge holder for a core plug of porous rock adapted to allow immersion of said core plug in at least one liquid, said centrifuge holder comprising:(a) an outer enclosure comprising: i) an elongated tubular member having an opening at one end permanently sealed to form a cup-like member; ii) a lid for sealingly closing the opening of said cup-like member; (b) an interior assembly for holding said core plug, wherein said interior assembly containing said core plug is adapted for disposal within said cup-like member, said interior assembly comprising: i) a first flat disc shaped end member; ii) a second end member shaped as a flat annular ring having a circular opening adapted for closely receiving said core plugs; and iii) a plurality of bar-shaped connecting members, each of which is lengthwise connected at evenly spaced intervals between said first and second end members, and wherein an outer edge of each of said plurality of connecting members is positioned adjacent the periphery of said first and second end members, and an inner edge of each of said connecting members is positioned adjacent the periphery of said annular opening in said second end member for containing said core plug; and (c) wherein the bulk volume of empty space in said outer enclosure when containing said core plug is much greater than the volume of liquid contained in said core plug, and is sufficient to allow immersion of said core plug in liquid.
