鸡西盆地煤层气资源量评价

Coal bed gas resource quantity evaluation in Jixi basin

准确的估算煤层气资源量是煤层气资源评价重要的任务之一。在收集和分析鸡西盆地500余个钻井资料、58个瓦斯解吸钻孔资料、多年矿井瓦斯涌出量及采集和测试大量样品的基础上,并根据不同的地质影响因素,采用不同的含气量计算方法,将盆地分成六个区块计算含气量,从而较科学合理地评价了盆地的煤层气资源量,为鸡西盆地煤层气资源勘探与开发提供了依据。

Calculating coal bed gas resource more accurately is one of the important tasks in the evaluation of coal bed gas resource.Based on collecting and analyzing the records of more than 500 drilling wells in Jixi basin,gas analysis on 58 drilling wells,several years of mine gas-gushing quantity and a lot of records of specimen's test,according to different geological influence factors.adopting different calculating methods and separating the basin into six sections to calculate coal bed gas content, we evaluate coal bed gas resource quantity reasonably and scientifically.The paper can supply the proof for the coal bed gas resource exploration and exploitation in Jixi basin.
