摘要
针对芦岭井田煤层碎软、低渗透、煤层群的特点,深入分析了井田地质、储层特征和煤层气地面抽采过程中的技术难点,通过探索试验和研究,提出了具有针对性的解决方案。在总结完善现场工程试验的基础上,形成了适合芦岭井田煤层气地面抽采的工艺技术,为该井田地面煤层气规模化抽采提供有力的技术支撑。
Under the condition of deformed coal seam, low permeability and coal seam group in Luling coal field, the geology and reservoir characteristics and technical difficulties for surface coalbed methane drainage are thoroughly analyzed. The targeted solutions are put forward upon the tests and research to coal seams. Based on the summary of development activities, a set of CBM development technology is formed to produce CBM in Luling coal field.
