摘要： Systems and methods particularly suitable for open hole formation testing are provided. In a described embodiment, a method of performing a test on a formation intersected by a wellbore includes the steps of flowing fluid into an apparatus from the formation, displacing a fluid barrier of the apparatus in one direction, flowing the formation fluid out of the apparatus and back into the formation by applying pressure to the apparatus, and displacing the fluid barrier in an opposite direction.

摘要： A fluid sampler operable for taking at least one fluid sample in a subterranean well and associated methods. A fluid sampling method includes the steps of disposing a fluid sampler at a first target location in the well, receiving the fluid sample into at least a first sample chamber of the fluid sampler, pressurizing the fluid sample in the first sample chamber using a pressure source of the fluid sampler, retrieving the fluid sampler to a surface location, isolating the fluid sample in the first sample chamber from the pressure source of the fluid sampler and supercharging the fluid sample in the first sample chamber using a pressure source on the surface.

摘要： An apparatus for actuating a pressure delivery system of a fluid sampler. The apparatus includes a housing (302) having a longitudinal passageway and defining first and second chambers (338, 348). A piston (346) is disposed within the longitudinal passageway between the first and second chambers (338, 348). A valving assembly (356) is disposed within the longitudinal passageway. The valving assembly (356) is operable to selectively prevent communication of pressure from a pressure source of the fluid sampler to the second chamber (348). The valving assembly (356) is actuated responsive to an increase in pressure in the first chamber (338) which longitudinally displaces the piston (346) toward the valving assembly (356) until at least a portion of the piston (346) contacts the valving assembly (356), thereby releasing pressure from the pressure source into the second chamber (348) and longitudinally displacing the piston (346) away from the valving assembly (356).

摘要： An apparatus (100) for obtaining a plurality of fluid samples in a subterranean well includes a carrier (104), a plurality of sampling chambers (102) and a pressure source (108) of the apparatus (100). The carrier (104) has a longitudinally extending internal fluid passageway (112) providing a substantially smooth bore therethrough and a plurality of chamber receiving slots (159). Each of sampling chamber (102) is positioned in one of the chamber receiving slots (159) of the carrier (104). The pressure source (108) is selectively in fluid communication with each of the sampling chambers (102) such that the pressure source (108) is operable to pressurize each of the sampling chambers (102) after the samples are obtained.
