Abstract(s) :

(Anglais) To face the challenges of oil production today, the mechanical behavior of rocks is to be studied under very specific conditions. In particular, thermo-hydro-mechanical couplings are important concerns in geomechanics of the drilling and reservoir engineering. In the Mining Engineering department of the Faculté Polytechnique de Mons (Faculty of Engineering, Mons - Belgium), we developed a new triaxial system to reproduce great depth conditions. Starting with a triaxial cell equipped with pore fluid provisions, a heating jacket and temperature control system, we designed and built a complete automated triaxial device comprising : a stiff loading frame, hydraulic equipments to control the stresses and pore fluid pressure, an electronic interface with a microcomputer, and we also developed a software to drive the tests and process the results. The equipment is designed for confining stresses and pore pressures up to 70 MPa and temperatures up to 232°C. This paper describes this apparatus and also reports the results of tests performed on a porous rock for validation.
