Abstract
A sample S is placed in a rigid body 1 of a device, in a containment cell laterally delimited by a supple sheath 21 and, at the two opposite ends thereof, by two cell ends 13, 14. Channels (15, 16) in these ends communicate with the sample, by means of semipermeable membranes (17, 18), and with fluid circulation means including a pump (39) providing a first fluid (such as water), a column (28) for injecting a second fluid such as oil, two burets (33, 36) receiving the fluids displaced out of the sample and a supply assembly (43, 46) associated with valves, providing gas that can be applied to the injection column (28) in order to push the second fluid injected into the containment cell for measurements with three-phase fluids. The device and its method of operation can be used for studying geologic samples, for example.
