Abstract

L'objectif de ce travail était d'élaborer une méthode simple permettant de différencier rapidement deux types de réducteurs de filtrat utilisés couramment dans les fluides à base d'eau, à savoir: cellulose polyanionique (PAC) et carboxyméthylcellulose (CMC). Cette méthode se fonde sur les différences de volume de filtrat obtenus à partir de formulation des deux produits, une fois le polymère dissous dans une solution d'électrolyte saturée. <br> The aim of this work was to find a simple method to quickly differentiate two types of fluid loss reducer, classically used in water based formulations, i. e. polyanionic cellulose (PAC) and carboxy methyl cellulose (CMC). This method is based on differences between filtrate volumes between the two, when the polymer has been dissolved in saturated electrolyte solutions.
