In this work, a novel oil field clay anti-swelling agent triethylallyl ammonium bromide (TEAAB) was prepared. The effect of reaction condition on TEAAB yield was studied, and the optimal reaction conditions is reaction temperature 60 °C, reaction time 7 hours, and molar ratio of raw materials of (triethylamine: bromopropene) = 1.4. Anti-swelling results showed that TEAAB has an excellent anti-swelling performance and the anti-swelling rate is up to 98% when the dosage was 6%.
