摘　　要：介绍了酯基基液的基本特性 ,探索了酯基钻井液的基本配方并对其性能进行了评价。评价结果表明 ,由酯基基液配制的合成基钻井液流变性好 ,抗海水及钙镁侵污能力强 ,各项指标符合环保要求 ,钻屑可直接排海 。The basic physical and rheologic properties of an ester base for drilling fluids are introduced briefly. A basic formulation of ester base drilling fluid(EBDF) is obtained through use level selection of 3 main additives in ester+25% CaCl 2 solution(7∶3). The performance properties of EBDF are investigated for resistancies to contamination by Mg 2+ , Ca 2+ and sea water, thermal resistancy, reservoir damage, and biological toxicity.
