摘　　要：控压钻井技术是当前最先进的钻井技术之一,它是在欠平衡钻井技术的基础上发展起来的。文章从基本概念、工作原理出发,对比了两者的分类、主要设备、应用目的、优缺点、适用范围、发展关键要素等。这有助于弄清它们的异同点,在充分利用现有欠平衡钻井技术的同时,更快更好地发展控压钻井技术,解决钻井中的难题。Managed pressure drilling (MPD) is one of the most advanced drilling technologies, and it is developed from the underbalanced drilling(UBD) techniques. In this paper, based on the basic concept and working principle of MPD and UBD, the classification, main equipments, application purpose, advantages and disadvantages, scope of application, key elements of development and so on were compared. This helped us to understand their similarities and differences, in the full use of existing under-balanced drilling technology, developing managed pressure drilling technology can solve many drilling difficulty.
