摘要: A study was made of the influence ionic strength (S) on apparent (AV) and plastic (PV) viscosities water loss (WL) sodium bentonite suspension with polymers. Na-bentonite dispersed in (4.86% w/w) different strengths (S = 0.0, 0.015, 0.030 0.045 M) followed by addition polymer. Three polymer samples were studied, i.e., low viscosity carboxymethyl cellulose (CMC BV), polyanionic (PAC), partially hydrolyzed polyacrylamide (HPAM). The results indicated that presence salts increased salinity greatly suspensions
