摘要

阐述了不同煤阶煤层气富集规律，总结了中高煤阶沉积控藏、水动力控气、断裂控制的特征，并指出是否具有充足的气源补给和良好的封盖条件是低煤阶富集的关键。在煤层气地质资源量计算上虽然仍利用体积法，但随着煤层气勘探开发工作的进一步开展，详实的资源评价参数大大增加了计算结果的准确性，同时丰富可采资源量的研究方法，进一步提高了其结果的可靠性。结合我国煤层气资源分类分布结果，总结了我国煤层气资源整体上“南北分区、东西分带”的特征，即由东向西从相对富气带转变为相对贫气带，由北向南从压力类型区渐变为应力类型区，处于中间地带的华北、鄂尔多斯等盆地容易形成富集高产区。

Abstract

The enrichment regularity of CBM in different coal rank is described.The characteristics of the medium-high coal rank sedimentary controlled reservoir and hydrodynamic gas control and structural adjustment are investigated.Sufficient gas source supply and good sealing conditions are keys to the enrichment of low-rank coal.With further exploration and development of CBM,more and more detailed resource evaluation parameters and rich and reliable research methods,as well as the accuracy and reliability of the results of the evaluation of resources have been further exactituded.Combined with China’s CBM resources classification and distribution results,this study summarized the coal seam gas resources in our country as a whole “North and South Division,East and South Area”.From east to west,it changes from a relatively rich gas into relatively poor gas zone,and from north to south it changes from pressure type area to gradient force type region.In the middle zone of North China,Ordos Basin is easy to form a high yield zone.

Key words： Coal bed methane; Enrichment pattern; Geological resources; Recoverable resources
