| 摘 要： | 本文以对国内外煤层气地球物理探测理论与技术研究现状进行系统回顾和分析的基础上，以淮南矿区主采煤层131煤为例，详细分析和研究了不同结构煤层的测井曲线特征及其与煤层气富集之间的关系；分析研究了多波多分量地震勘探技术在煤层气勘探中的应用基础和主要技术方法，并建立了煤层气富集区预测的测井参数门限和多波地震勘探的技术指标，首次明确指出煤层气富集区和煤矿瓦斯突出灾害区有本质不同，并在地球物理标志中有明显的分辨特征。

| Abstract: | Based on the method of geophysical exploration for the coal bed methane(CBM),the relationship between CBM enrichment area and well logging characteristic of different structural coals were studied for the Seam 13-1,Huainan coalfield.The basic technology of multi-wave and multi-component seismic exploration applied in CBM exploration were discussed,meanwhile logging parameters threshold and technical index of multi-wave as well as multi-component seismic exploration for forecasting CBM enrichment area were proposed.It indicates that between CBM enrichment area and gas outburst area presents an essential difference,which shows significant discrimination characteristics on geophysics. |

| Keywords: | coal bed methane(CBM) enrichment area gas outburst area well logging technology the multi-wave and multi-component seismic exploration |
