摘　　要：华北油田的大部分油藏已进入开发中后期,但剩余储量规模仍然相当可观,实施欠平衡钻井技术是提高勘探综合效益的一条行之有效的途径。近两年,华北油田的欠平衡钻井技术发展迅速,欠平衡钻井液的合理设计是欠平衡钻井成功的关键之一,而钻井液的开发和应用必须和现场紧密结合,因此,如何开发适宜的适应本地区地质特征的欠平衡钻井液是今后发展的重点,本文阐明了华北油田地区对欠平衡钻井液的要求,介绍了欠平衡钻井液尤其是无荧光水包白油的现场应用,以及今后面临的挑战。For Huabei Oilfield, it has entered into the medium or late period of the exploitation, but the oil reserves is still large. Under-balanced drilling （UBD） technology is really a beneficial way, which has just been used in Huabei Oilfield. Drilling fluid is one of the keys for the success of UBD. As we all know, the study of drilling fluid is based on the local oilfield conditions, so the research of UBD drilling fluid, fitting the geological character of Huabei Oilfield is very important. The paper summarized the application of UBD drilling fluid in Huabei Oilfield, and pointed out the future challenge.
