Clay stabilizer composition and preparation method thereof

The invention relates to a clay stabilizer composition and a preparation method thereof, the main components of the clay stabilizer composition are a modified cationic polymer stabilizer and an auxiliary clay stabilizer, and the modified cationic polymer stabilizer is synthesized by using a hyperbranched polymer as a matrix; the auxiliary clay stabilizer contains a benzene ring and a triazole structure, both the benzene ring and the triazole structure have good thermal stability, so that the clay stabilizer composition has good high temperature resistance, and the modified cationic polymer stabilizer is further grafted with a silane segment, so that the clay stabilizer composition has good water washing resistance, and the service life of the clay stabilizer composition is prolonged. The molecular weight of the auxiliary clay stabilizer is small, so that the auxiliary clay stabilizer can enter a pore channel into which the modified cationic polymer stabilizer cannot enter, and the modified cationic polymer st
