摘要： 介绍了国外欠平衡钻井的发展与应用,以及目前存在的主要问题。在此基础上提出了低压欠平衡钻井技术系列,它是一套特殊工作液(气体、充气液、特殊泡沫、低密度液体)、特殊压力控制(平衡、欠平衡、过平衡)、低液柱压力与特殊屏蔽暂堵相结合的技术。
关键词: 勘探钻井, 低压钻井, 欠平衡钻井
Abstract: The development and application of under-bal-anced drilling in abroad are reviewed, and the exist-ing problems of this technology are discussed. Basedon these, the technology of low pressure drilling, an integration of special drilling fluid (air, aerated flu-id, special foam, light fluid), special pressure con-trol (balanced, underbalanced, overbalanced), low head pressure and special temporary plugging, is suggested.
Key words: Underbalanced drilling, Problems, Low pressure, Drilling fluid, Pressure control, Temporary plugging
