摘　　要：油气井下完井管柱前,需要拆除钻井四通或者修井四通,更换试压合格的采油(气)大四通。在拆装大四通前需要对井筒进行临时封堵作业,确保作业井控安全,但额外增加施工成本和施工周期,占用油气井投产的时间。结合临时封堵和完井工具及施工工艺,采用完井-临时封堵管柱一体化工艺,在现场应用成功。Before running the completion string into oil and gas wells,the drilling or workover spools must be removed and replaced with qualified tubing spools.Temporary plugging operations are required to ensure well control safety before removing and installing the spools,which increases job costs,time,and delays well production.By integrating temporary plugging and completion tools with treatment technology,this integrated completion string and temporary plugging technology was successfully applied on-site.
