摘　　要：从储层保护角度,阐释了实施全过程欠平衡钻、完井的意义。从工艺角度给出了实现全过程欠平衡钻井、完井所需要的关键装备,同时提供了实现钻进、起下钻、测井、完井等作业条件,保持井筒欠平衡状态的工艺方法。文中,介绍了近年应用全过程欠平衡钻井技术在新疆油田克拉美丽气田取得的发现、保护效果。最后,对全过程欠平衡工艺在油田应用与推广给出了认识与建议。This paper explains the significance of carrying out underbalanced drilling/completion technology in whole process from the perspective of reservoir protection, introduces the key equipment to carry out the whole process underbalanced drilling/completion technology from the technology point of view,and provides a realization of drilling,tripping,logging,completing and other working conditions,to maintain the wellbore being in underbalanced condition. It introduces the detection and protection effect that was obtained from the application of this technology in Karamay gas field of Xinjiang. Some suggestions are made about practicing and spreading this technology in oil filed in the final part.
