Abstract: A fluid separating device comprises: a cylinder; a plurality of separators disposed around a cylinder; a first elastic piece disposed between one of the separators and the cylinder and applying an elastic force to the separator outwardly in the radial direction of the cylinder; a first guiding device passing through the cylinder axially and configured to reciprocate between an expanded position and a contracted position in the axial direction of the cylinder; a second guiding device penetrating the cylinder, connected to the separator at one end, and slidably fitted with the first guiding device at the other end via a fitting surface. The fluid separating device eliminates the friction between the separator and the inner wall of the wellhole when descending, therefore descending to the bottom of the well quickly.

Abstract: An anchor structure is disclosed; the anchor structure is set on a mandrel of a downhole plugging apparatus. The anchor structure comprises (a) a clamping device, (b) a plurality of slips and (c) a conical slip holder, wherein the slips are connected to a conical face of the conical slip holder, and (d) a containing space between the clamping device and the slips; the anchor structure further comprises (e) a stroke pressure compensating device which is set within the containing space and can be compressed to provide pressure for the slips, wherein the containing space is designed to be able to accommodate whole or part of the stroke pressure compensating device in the situation that the slips are anchored into a wellbore wall and the clamping device is in contact with the conical slip holder. The containing space would prevent the stroke pressure compensation device from being damaged or extruded completely, and preclude the clamping device from contacting the slips directly when the slips retract.
