摘　　要：1999年 ,在全国各油田掀起了一场引进、研究和应用欠平衡钻井技术的高潮。目前欠平衡钻井在我国并未形成一个系列 ,引进的欠平衡钻井专用设备仅仅用于地层压力高于 1 0或略低于 1 0的地层 ,与国外相比还有很大差距 ,特别是泡沫、氮气的欠平衡钻井系列国内尚未起步。如何有效地发展国内欠平衡钻井技术 ,文中介绍了国内外欠平衡钻井技术的发展情况 ,欠平衡钻井技术的优越性及其分类 ,并对国内的欠平衡钻井应用领域进行分析 。In 1999,there was a climax of lead in the equipment of underbalanced drilling,researching and applying the underbalanced drilling in China.The equipment of underbalanced drilling operation introduced from foreign company is only used in formation,which porosity pressure is high or a little lower than 1.0.The progress of underbalanced drilling in China compares with abroad,there is a big distance.Especially the foam,nitrogen etc.underbalanced drilling technology isn't underway.This paper brief introduces the development of underbalanced drilling technology on abroad and in China,the advantage and classification of underbalanced drilling.Meanwhile,analyses the application of underbalanced drilling technology in domestics oilfield,and puts forward several suggestions on developing underbalanced drilling technology in China.
