摘要
煤层渗透率不仅是评价煤层气勘探开发潜力的重要地质参数,也是选择钻井、完井方式的关键参数之一。本文在系统分析比较了国外煤层气开发的成熟经验和工程技术特点的基础上,提出了根据煤储层渗透率的不同来选择钻井完井方式的基本理念和策略,以期为煤层气钻井完井工程的经济有效实施提供一定的参考借鉴作用。
The permeability in coal seam is not only the important geologic parameter to evaluate the CBM po- tentiality of exploratory development, but also one of the key parameters to select drilling & completion meth- ods. Firstly, the systematical analysis and comparison based on the mature CBM development experience and engineering characteristic abroad are introduced. Secondly, one elemental strategy of the selection of drilling & completion methods in accordance with the permeability in coal seam is proposed. Finally, some valuable advices are provided for the efficiently economical field operations of the drilling & completion engineering.
