煤层气多分支水平井钻井技术研究
Study on Coal Bed Methane Multi-branch Horizontal Well Technology
摘要
煤层气多分支水平井钻井技术的应用极大地促进了煤层气的开发,是煤层气开发的主要工艺之一。本文简要分析了煤层气多分支水平井的增产机理和基本模式,并剖析了该工艺中井位优选,井眼轨迹控制,钻井液设计等重要环节的技术要点。
Abstract
Multi-branch horizontal well technology, as one of the main technology for coal bed （CBM） development, remarkably promotes the exploitation of CBM. In this article, the basic principle of this technology is introduced. Meanwhile, the key points in this te
