摘　　要：文中研制出一种有机胺抑制剂,并对其性能进行了评价。实验结果表明,有机胺能将表面张力降低到50mN·m-1,对黏土的Zeta电势影响不大,能有效抑制黏土造浆和岩心及岩屑的分散,且其抑制性持久性强;有机胺抑制剂与钻井液配伍性好,有利于维持钻井液的高温稳定性,且对钻井液滤失性能具有一定的改善作用。An organic amine inhibitor was developed and evaluated. Experimental results showed that the organic amine inhibitor could reduce the surface tension to 50 mN·m-1 and had a little effect on the Zeta potential of clay. The inhibitor could effectively inhibit the dispersion of core and cuttings and had a lasting strong inhibition. The inhibitor had good compatibility with common drilling fluid, and it was useful to maintain drilling fluid stability under high temperature and could improve the filtration property of drilling fluid.
