摘要：

To improve the solubility of a kind of plant polysaccharide derivative (Si) in drilling fluid system, it was modified by cationization with GTA as cationic etherifying agent. The reaction conditions were investigated by orthogonal designed experiments, and the optimized conditions were as follows: the mass ratio of GTA to Si is 0.6g/1g with pH 12 at the temperature of 90 degrees C. The viscosity of cationic Si (CSJ) drilling fluid system was greatly improved and the temperature had a slight effect on rheological properties below 100 degrees C. The inhibitive property of CSJ is evaluated by clay-swelling tests and the mud ball immersing tests, which is obviously stronger than Si and even more effective than 4%wt KC1 solution.
