| Résumé: | Bentonite is often used in water-based drilling fluids. The xanthan gum is widely used as to
increase the viscosity of the bentonite suspension. For the stabilization of the drilled layers, we use filtrate
reducers: sodium carboxymethylcellulose low viscosity and cellulose polyanionic low viscosity. The objective
of this work is to explain the effect of the polymers on the rheological behavior of the 5% bentonite
suspensions. These results will provide practical recommendations for the rational use of different types of
additives in water-based drilling muds. Our work is based on rheological trials on a viscometer. The results
obtained on the bentonite 5%-xanthane suspension show a rheofluidifying behavior with yield stress conform
to the Herschel-bulckly modal. While increasing the concentration of filtrate reducer decreases the yield stress
and reduces the viscosity. The effect of CMC LV is more pronounced than PAC L |
