摘　　要：本文介绍了甲酸铯钻、完井液的特性与应用情况,包括:与弹性体相容性、腐蚀性、润滑性、热稳定性、储层保护、环境安全、再生利用等。自1999年作为射孔液应用以来,截至2009年10月,甲酸铯盐水在高温高压井中的应用已达220井次。现场应用表明,使用甲酸铯钻、完井液减少了井下复杂情况与事故的发生、缩短了建井周期、提高了油井产能及石油采收率。The characteristics and applications of cesium formate brine as drilling and completion fluids were presented and following topics were covered： compatibility with elastomers,corrosion,lubrication,thermal stability,reservoir protection,environmental safety,recycling,etc.Up to October 2009,cesium formate brine had been applied in HTHP wells for 220 times,and the application in the field showed that the use of cesium formate brine could reduce downhole accident,shorten the well construction period,and increase oil production and recovery.
