国外分枝水平井钻井技术发展现状

DEVELOPING STATUS OF FOREIGN LATERAL HORIZONTAL WELL DRILLING TECHNIQUE

随着水平井钻井技术的日益成熟，目前分枝水平井钻井技术在国外已有了很大发展。本文根据近十年来英、美、俄等国家的有关资料，对国外分枝水平井钻井技术发展现状、主要设计原则、工艺技术、钻井液技术、主要完井技术及其实例分别给予介绍，最后对大庆油田钻分枝水平井进行了可行性分析。

With horizontal drilling technology becoming mature,foreign lateral horizontal well drilling technique has got great development. The paper introduces separately developing status,main design principle,technology,mud technique,main well completion technique and examples of foreign lateral horizontal well drilling. And feasibility analysis of drilling lateral horizontal well in Daqing Oilfield is made.
