摘　　要：欠平衡钻井技术已经在陆地油气田开发中得到了广泛的推广和应用,由于作业环境的特殊性,在海上的应用相对较少。目前欠平衡钻井技术在海上推广应用中存在的主要问题涉及平台甲板空间、安全环保、组织管理模式等方面。近年来,随着新型工具的开发和技术的发展,这些问题正在逐步得到解决。海上欠平衡钻井最新进展包括先进的井下工具的开发、设备的模块化与小型化、对油藏分析与研究的高度重视以及工作船与欠平衡钻井设备的一体化。钻井平台与欠平衡钻井设备的一体化是海上欠平衡钻井的发展趋势。As an advanced drilling technology, UBD (Under balanced Drilling) has been applied widely in the development of oil and gas fields onshore. However, its offshore application is restricted by the special offshore operation conditions. The main problems for wide application of UBD offshore are the platform space, HSE, organization and management model, etc. Recent years, these problems have been solved gradually along with the development of new technologies and tools. The recent advance of offshore UBD technology includes the development of advanced down hole tools, modularized and minimized design of UBD equipment, emphasis on reservoir analysis and study, and integration of UBD equipment with offshore rig or barge. Dedicated UBD drilling rig intend to be a better alternative in future offshore operation.
