| 摘 要： | 自1999年9月壳牌公司首次使用甲酸铯钻井液以来，到2009年10月，世界上已有18家石油公司在220多口高温高压井中使用甲酸铯/钾盐水进行钻井、完井及修井等作业。甲酸铯/钾钻井液、完井液具有无固相、气体溶解度和腐蚀性低、润滑性和相容性好及储层伤害性低等特点，很好地解决了高温高压井中常规钻井液存在的缺陷。气体溶解度低能够较好地控制井涌；润滑性能好能够降低摩阻和扭矩，从而降低压差卡钻的风险，提高机械钻速；相容性好、储层伤害性低能够降低修井需求，提高采出速度；可生物降解能降低HSE风险。基于对卡博特公司的甲酸铯手册及国外发表的有关甲酸铯/钾钻井液和完井液文献的深入分析，介绍了国外甲酸铯/钾钻井液和完井液的常用处理剂、配方，应用现状及回收利用情况，并对其应用前景进行了分析。
