芦岭井田煤层气开发地质条件及开发方式选择

The selection of suitable development method and geological conditions of CBM development in Luling coal district

  • 摘要: 我国煤层气地质条件复杂,针对不同地质条件,选择合理的煤层气开发方式,对煤层气抽采非常重要。分析研究芦岭井田煤层气开发地质条件显示:芦岭井田构造及水文地质条件较复杂;目标煤层发育层数多,厚度大,煤层埋藏较深,且分布较稳定;煤层主要为构造软煤,渗透性较差,气含量较高。通过对目前煤层气不同开发方式的适用性分析,结合芦岭井田的煤层气开发地质条件,在目前经济技术条件下,优选出地面垂直井为本区煤层气的首选开发方式。

     

    Abstract: With the complex geological conditions of CBM in China, it's particularly important to select suitable development method of CBM in different areas. According to the study of the geological conditions of CBM development in Luling coal district, the main results are as follow:the geological conditions of CBM development in Luling coal district are complex. Great number of target seams have been developed, thick and have stable distribution. The coal seams are mainly tectonic soft coal, high in gas content, poor in permeability. Through analysis of the adaptability to different CBM development modes and in combination of CBM development conditions in Luling mine as well as under the present economic and technical conditions, vertical wells are the way of first choice for CBM development in the area.
