河北大城地区煤层气风氧化带深度研究及其意义

Significance and Research on Depth of Coalbed Methane Oxidation Zone in Dacheng Area of Hebei Province

针对河北大城地区煤层埋藏较深,而煤层含气量偏低的问题,探讨了煤层气风氧化带深度在其中所起的作用。研究认为煤层上覆有效地层厚度和新生代地层厚度是影响大城地区煤层气风氧化带深度的主要因素。

According to the problem of lager burial depth of coal seam and lower coalbed methane(CBM) content in Dacheng area, Hebei province, studying the impact of depth of oxidation zone.Research shows thickness of effective strata overlying the coal seam and thickness of Cenozoic strata are the main factors which affect depth of oxidation zone.
