Cationic alkyl polyglucoside is a new type of cationic surface active agent which was developed rapidly based on alkyl polyglucoside.  It was found that cationic alkyl polyglucoside has excellent performance in drilling fluid.  In this paper, the synthesis method of cationic alkyl polyglucoside was introduced and the related performance was tested preliminarily.  The results showed that cationic alkyl polyglucoside which was synthesized by us had excellent surface activity, inhibition, temperature resisting and lubricity, in which, surface tension 30.9 mN/m, cuttings relative recovery was more than 99.01 %, resisting temperature was higher than 423 K, lubrication coefficient 0.16.  Each performance of cationic methyl glucoside was better than methyl glucoside.  It was predicted that cationic alkyl polyglucoside has very wide application prospects in drilling fluid.
