The drilling fluid, which was originally considered like a vehicle of transportation of cuttings is now recognized as one of the major factors for a successfully drilling operations. The success of the drilling operations mainly depends on rheological parameters of fluids (muds), the choice of an adequate mud to the specific particularities of a crossed formations and to a geological conditions permits therefore, not only to increase the efficiency of drilling apparatus, but also to avoid the damage (plugging) of producer layers allowing a better productivity of a drilled well. Two approaches have essentially been considered for the modelling of rheological behavior of different systems of drilling muds. The rheological models integrate one or several characteristic parameters of the fluid or the type of behavior: viscous, pseudoplastic or viscoplastic. These models suppose that the structure of the fluid is steady, therefore, the time of application of the constraint or shearing doesn't influence the model. The aim of this work is to study the influence of the pressure and the temperature on rheological behavior of drilling fluids composed of emulsions of oil, water and different additives.
