摘　　要：针对欠平衡钻井对低密度钻井液的要求,以水包柴油乳状液为研究对象,通过实验优选乳化剂,研究了2种和多种乳化剂协同作用下水包柴油乳状液的稳定性,优选出了抗温性能好、乳化能力强的复合乳化剂,配制出了抗180℃高温的水包油乳状液。For the requirement of low-density drilling fluid used in under-balanced drilling, oil/water drilling fluid is studied, by means of experiments of emulsifier optimization and the synergy effect of two and multiple emulsifiers. Though experiments, the multi-emulsifiers with high emulsifying ability are chosen to formulate the o/w drilling fluid that can be used at 180 ℃.
