A mixture containing substances likely to settle or to flocculate is fed into a chamber (1a) of a body (1) delimited by a mobile piston (18) and a closed-circuit circulation of the mixture is established by means of a homogenization turbine (8) driven by a motor (28) associated with magnetic driving means (9, 26). According to the pressure and to the temperature, variations in the conductance of the mixture flowing between two electrodes (1, 16) connected to a measuring device (17) are measured on the one hand and variations in the driving torque applied to turbine (8) under the effect of the concomitant variations in the apparent viscosity of the mixture are measured on the other hand. The cell can be used to study of the conditions of formation of asphaltene deposits or flocculations in petroleum crudes for example.

A cyclone separating device includes a transparent and tapered separator flask, with an upper outlet where a tube provided with seal means and a tubular extension is fastened, and a lateral inlet through a lateral appendix communicating with the inside of the flask through a fine channel offset in order to generate a cyclone effect promoting the separation of the phases and lined with an insert made of a plastic material. The fluid sample is injected, for example, through a septum by means of a hollow needle guided through the insert. The device can be used for processing geologic fluid samples.

Apparatus for measuring thermodynamic characteristics of a hydrocarbon sample, comprising at least one measurement cell (12; 14) intended to be selectively connected to a gas gauge (82); the gas gauge being capable of being selectively connected to a gas recovery assembly (98) and a liquid storage assembly (114), the measurement cell (12; 14) comprising a piston/cylinder assembly (16; 20; 18; 22), the piston being movable in the cylinder under the action of a jack (24; 26).

Fluids kept under high pressure in one or several balancing cells (C1, C2) inside a thermostat-controlled enclosure (14) at about 200.degree. C. are extracted by introducing into the enclosure a sampling cell (1) capable of withstanding pressures of the order of 150 MPa, fastening cell (1) to a connection element (24) linked to balancing cells, taking samples and removing the cell from the thermostat-controlled enclosure, with all of these operations being easily conducted from outside. After possible weighing of the sampling cell, a transfer device thereafter allows the sampling cell to be communicated with measuring and analysis devices such as a gasometer associated with a separating bottle, a solvent injection means, etc. Operations are synchronized by a programmed microcomputer (MC). The preferred application is processing geological samples.

System for transferring samples under pressure

A method for transferring a fluid sample from a first chamber to a second chamber separated from the first chamber involves opening a closed cavity defined between the end portions of two coaxially arranged cylindrical rods while in the first chamber, then closing the open cavity in the first chamber to enclose the fluid sample, transferring the closed cavity from the first chamber to the second chamber by effecting axial movement of the rods relative to the chambers, then opening the closed cavity in the second chamber to allow the fluid sample to enter the second chamber. A device for carrying out this method is provided with first and second rods arranged to move along a common axis, the device including an arrangement for effecting displacement of the rods relative to each other and relative to the chambers or displacement of the rods together while the end portions of the rods are in contact to effect transfer of the fluid sample from one chamber to the other.
