The invention concerns an apparatus and method for determining pore volume parameters of a solid sample. The apparatus comprises a high pressure cell (50), a sample holder (1) provided with an orifice (21), means (2) for creating a vacuum connected to a chamber (10a) containing the sample holder by at least one orifice (30), and a mercury supply. The apparatus also comprises a syringe pump (9) connected to the chamber and to mercury supply means for delivery of mercury under pressure, means for programming a steady supply of mercury for a fixed period of time connected to the pump, at least one pressure sensor (15) downstream of the pump which continuously reads the pressure, and means (41) for signal collection and processing connected to the pressure sensor and the means for programming a steady supply of mercury and adapted to calculate the porosimetry parameters.

Method and apparatus for determining pore volume in a solid sample

A device for studying an aging of a fluid circulated in a loop or closed circuit by imposing, for example, predetermined temperature, pressure or shear conditions on the fluid in order to determine rheologic properties of the fluid. The device includes a loading pump, a circulating pump, a filtration governor pump and an injection and draw-off pump, a flow meter, a viscosimeter for discontinuous measurings, a narrowing or reduction for causing a shearing of the fluid, a number of filters interconnected in series, a sampling cell, pressure and temperature pickups, heating jackets and heat insulation sheaths for maintaining a homogenous temperature all along the loop, and a control system which includes a programmable automaton associated with a microcomputer in order to pilot numerous operating sequences. The device is constructed so as to maintain constant conditions imposed on the fluid regardless of the type of measurements being effected.
