| 摘 要： | 针对我国煤层气勘探开发的难题,从煤层气藏的气源和保存条件入手,深入分析了生物气作为气源在浅层低煤阶煤层气藏形成中的重要性,并研究了盖层条件、水文地质条件及甲烷菌的生气条件在浅层低煤阶煤层气藏的形成和保存过程中所起的作用.认为中国煤层气的勘探开发不应受氧化带的限制,在煤层上覆封盖条件较好的浅层寻找浅层低煤阶煤层气藏可能获得良好的经济效益.

| Abstract: | To solve the difficulties in the exploration and development of coalbed gas in our country,the importance of biogas in the formation of shallow low-rank coalbed gas pool is analyzed,and the effects of overlying conditions,hydrologic geology conditions and gas producing conditions of methane bacteria in the formation and conservation of the shallow low-rank coalbed gas pool are discussed.It is held that in our country,the exploration and development of coalbed gas should not be limited in oxidation zones,it may be successful to find low-rank coalbed gas pools in the shallow layers with good overlying condition. |

| Keywords: | coalbed gas over-saturated coalbed gas pool methane bacteria content of coalbed gas |
