羽状水平井技术是近年来才发展起来的一项快速开采煤层气资源的先进技术,其基本特点是单井产能高、开发周期短,特别适宜煤矿待采区的煤层气开采。煤层气多分支水平井技术是一套包括地质评估技术、钻井工艺配套与优化技术、完井技术、储层模拟技术、以及精细化排采管控技术在内的煤层气产能建设和煤矿瓦斯抽采的系列技术。
Pinnate horizontal well technology is an advanced technology developed rapidly in recent years. Its basic characteristics are high single well productivity and short development cycle, which is especially suitable for coalbed methane exploitation in the area to be mined. CBM multi-branch horizontal well technology is a set of CBM production capacity construction and coal mine gas drainage, including geological assessment technology, drilling technology package and optimization technology, completion technology, reservoir simulation technology, and meticulous drainage control technology Series of technologies.
