论文陈述 Paper Statement 本研究揭示了不同宏观煤岩类型的差异化控气机制:半亮煤是主要“储气核心,” 光亮煤为关键“渗流通道,” 暗淡煤则是“初期高产贡献者”。这为深层煤层气甜点优选与定制开发提供了关键理论依据。 This study reveals the differentiated gas‐controlling mechanisms of different macroscopic coal lithotypes: semibright coal acts as the primary “gas storage core,” bright coal serves as the critical “seepage channel,” and dull coal functions
