PACKER VARIABLE VOLUME EXCLUDER AND SAMPLING METHOD THEREFOR
摘要:
A down hole apparatus includes a first expandable packer and a second expandable packer, where the first expandable packer longitudinally spaced from the second expandable packer. The apparatus further includes an optional expandable bladder disposed at a longitudinal location between the first expandable packer and the second expandable packer. The expandable bladder inflates to displace drilling fluid between the first and second bladder elements. The down hole apparatus can optionally displace drilling fluid between the first and second bladder elements with another fluid. Fluids and/or slurry can be selectively removed using ports between the first and second expandable packers, and optionally placed in sample chambers, or expelled to the bore hole.
