In this work, the quaternary ammonium salt small molecule inhibitors with melamine and sodium chloroacetate as raw materials was synthesized and it has certain inhibition on the hydration swelling of bentonite. Through linear swelling test, mud ball test and drilling fluid performance evaluation, its inhibition performance in clay is evaluated. The results show that the linear swelling rate of bentonite in 0.5% MAA-3 solution is 57.28% at 90 min, which is similar to that in 4.0% KCl solution.
Key words: Synthesis / Hydration / Swelling / Performance
