总结分析工区内砂体的空间组合模式和时空演化关系,从而探讨3#煤层顶板砂体发育特征与煤层含气量之间的关系。结果表明,平面上砂体厚度越大其对应的煤层含量气越低,且平面砂体被泥岩包围型和砂体连片型对应的煤层含气量变化不同。同一厚度砂体连片型对应的煤层含气越低,而被泥岩包围的孤立型对应的煤层含气量越高。
總結分析工區內砂體的空間組閤模式和時空縯化關繫,從而探討3#煤層頂闆砂體髮育特徵與煤層含氣量之間的關繫。結果錶明,平麵上砂體厚度越大其對應的煤層含量氣越低,且平麵砂體被泥巖包圍型和砂體連片型對應的煤層含氣量變化不同。同一厚度砂體連片型對應的煤層含氣越低,而被泥巖包圍的孤立型對應的煤層含氣量越高。

Summary analysis work area sand body space combination mode and space-time evolution relationship, which discuss 3 # coal seam roof sand body development characteristics and the relationship between the coal seam gas content. Results show that the surface thickness of sand body, the greater the its corresponding to the lower content of coal seam gas, and the planar sand body surrounded by mudstone and sand body shall correspond to the different coal seam gas content changes. The same thickness of sand bodies shall model corresponding to the lower coal seam gas, and surrounded by mudstone isolated type of coal bed gas content is higher.
