摘　　要：汶川地震断裂带科学钻探项目4号孔(WFSD-4)地层极其复杂,钻探施工难度极大,对钻井液技术要求较高,据此优选钾石灰聚磺钻井液体系为该孔的钻井液主体系。介绍了钻井液技术在各开次的使用维护情况,同时还详细介绍了该孔中的特殊工艺钻井液技术及复杂情况下钻井液应对措施等。Formations were extremely complicated in WFSD-4 of Wenchuan earthquake fault scientific drilling project,and the drilling construction was also very difficult. Higher drilling fluid technology was required. The potassium lime polysulfonated drilling fluid system was selected as the WFSD-4＇s main system. The paper introduced the use and maintenance of drilling fluid systems used in each borehole section. In addition,the special process of drilling fluid technology and the response to complex situations are introduced in detail.
