摘　　要：泌深1井是中石化的一口重点探井,位于河南省唐河县毕店乡,完钻井深为6005m,实测井底温度达到236℃。通过室内实验优选出抗220℃和抗245℃2套超高温水基钻井液,并在现场进行了应用。应用结果表明,这2套超高温钻井液流变性好,具有较高的抗温能力、抑制能力和悬浮携带岩屑能力,摩阻系数低,泌深1井在四开高温井段的钻井过程中没有发生井下复杂情况,表明2套超高温水基钻井液满足了泌深1井钻井需要。Well Bishen-1,located in Tanghe county of Henan Province,is a key exploration well with a completion depth of 6,005 m,and a Downhole temperature of 236 ℃.Two water base drilling fluids for use at temperatures of 220 ℃ and 245 ℃ were designed and used in field drilling operation.The application of these two drilling fluids was successful in the well Bishen-1 drilling operation.
