摘要
在简介欠平衡钻井技术应用现状的基础上,论述了电磁波随钻测量技术(EM-MWD)的特点及其在欠平衡钻井中的适应性,认为把电磁波随钻测量系统用于欠平衡钻井中还需解决诸如加大井下信号频率的可调范围、井下仪器电源问题、接收信号的灵敏度、地面接收系统的抗干扰性、增加钻井测量参数等关键技术。
The paper briefly introduces the actuality of the underbalanced drilling, and describes the characteristics and adaptability of the electromagnetic wave measurement while drilling（EM-MWD）. When EMMWD is applied in underbalanced drilling, it is needed to solve some key problems, such as the adiusting range of transmitting frequency,the power life of downhole instrument, sensitivity of received signals, disturbing resistency of receiver on surface and the number of measuring parameters of drilling.
