Abstract: A novel organsilicone-modified cationic starch filtrate reducer(OSCS) was prepared from hexamethyldisilazane,phenyl amine,carboxylmethyl starch(CMS) etc.The filtrate reducer with high temperature-resistant capability was used for drilling fluid.FT IR indicated that both the phenyl cation group and organic silicon functional group were introduced into the structure of carboxymethyl starch(CMS).Furthermore,its thermal stability was characterized by TG-DTA,showing that the decomposition of OSCS was...
