摘　　要：欠平衡钻井技术(controlled pressure drilling)作为现代钻井技术的一种方式,越来越受到人们的重视,其原因不仅在于欠平衡钻井技术一些固有的优点,勘探开发作业越来越多的转移到难开发地区、低孔低渗储层和衰竭油气藏的开发也是欠平衡钻井得以蓬勃发展的另一个重要原因。文章根据在全球几十个国家的作业经验讨论了欠平衡钻井在国际上通用的分类、IADC对每一项分类的定义、各项技术的优缺点、局限性以及使用设备。Controlled pressure drilling(CPD)is one of the advanced drilling techniques and becoming more and more popular,it is not only because of the inherent advantages of CPD,the exploration in complicated geologic area,the development of low permeability,low porosity and depleted oil&gas reservoir is another reason of making CPD developing fast.This paper discusses the classification of CPD,IADC definitions,advantages and disadvantages of each technique.The paper as the CPD engineer was involved in the design and operation of each technique around the world.
