Device for studying physical properties of a solid sample (S) in the presence of fluids, at relatively high temperature and pressure. The device comprises an elongate rigid body ( ) closed at the opposite ends thereof by two covers ( ), a flexible sheath ( ) around the sample, cooperating with two end pieces ( ) so as to delimit, inside the rigid body, a containment vessel, injection means for displacing fluids under pressure through the sample in its sheath, measuring means for measuring various parameters of the sample and means (P) for injecting a fluid under pressure around flexible sheath ( ) so as to exert a radial pressure and possibly an axial pressure around the sample, means for heating the fluid under pressure associated with at least one of the two covers ( ) and means including a turbine ( ) for example, for homogenizing the temperature around the sheath by circulation of the fluid heated on contact with the heating means. The body is preferably made of a composite material. The device can be applied for: study of geologic samples for example.

Device for testing rock samples at relatively high pressure and temperature

The invention is a device for separating a mixture of fluids (conducting fluid, non-conducting fluid, gas), suited to measure the volumes of the various fluids by means of a capacitive measuring process. The invention comprises a unit (WOS) for separating a conducting liquid phase and another, non-conducting liquid phase or non-conducting gas phase that's immiscible with said first phase along an intervening interface, comprising an elongate tubular vessel (T) whose outer wall (,) is made of a conducting material and whose inner wall (,) is made of an insulating material, this vessel being arranged vertically in operation, a conducting element (,) in contact with the conducting first phase, that can be combined with a second unit (GOS) for separating a non-conducting liquid and a gas, comprising a second elongate tubular vessel (,) made of a conducting material placed above the first unit, an elongate electrode (,) arranged substantially in line with the second vessel and electrically insulated therefrom a capacitance measuring unit (,) that is connected by conductors (LI-L,) to conducting element (,), to the outer wall (,) of the first vessel, to second vessel (,) and to electrode (,), and fluid supply means (,). The invention may be used to monitor interfaces at high temperature and pressure, notably for petrophysical measurements for example.
