摘要

在总结阳泉矿区寺家庄井田含煤地层发育特征的基础上,从气测录井检测入手,分析了煤层气即时含量高的含煤地层层位,依据煤岩性质和煤层厚度2个方面对含煤地层具有较高开发潜力的层位进行预测,结果显示8~#煤和15~#煤具有较大的煤层气开发潜力。气体碳同位素分析结果显示8~#煤中的气体并不包含来自于下伏煤层的煤层气,15~#煤的气体有向上运移的迹象。研究成果可指导地面煤层气井的开发。
        On the basis of summarizing development characteristics of coal bearing strata of Sijiazhuang mine in Yangquan mining area, starting from the test of gas logging, the coal bed layer with high instant content of coal bed gas was analyzed. According to the two aspects of coal and rock properties and coal seam thickness, layers of coal bearing strata with high development potential were predicted.The results show: 8~#coal and 15~#coal had great potential for development of CBM. Results of gas carbon isotope analysis showed: gas in 8~#coal does not contain coal bed gas from the underlying coal seam, upward movement of the gas in 15~#coal is signed. Research results could guide the development of coal seam gas well on the ground.
