俄乌哈三大煤盆地煤层气地质及开发潜力对比研究

俄罗斯、乌克兰和哈萨克斯坦（俄乌哈）三国拥有丰富的煤炭资源和煤层气资源。在美国实现煤层气商业化开发的引导下，这三大独联体国家也逐渐开展本国的煤层气勘探开发。本文在分析俄乌哈三大煤盆地（库兹涅茨克、顿涅茨和卡拉干达）构造、地层及煤层气地质特征的基础上，详细地分析这三大煤盆地煤层气开发潜力，并对其开发潜力进行仔细地对比研究。研究表明：库兹涅茨克煤盆地煤层气发育具有“巨大且巨富”的特征，非常适合煤层气规模化开发；卡拉干达煤盆地煤层气发育具有“小而肥”的特征，同样适合煤层气开发；而顿涅茨煤盆地煤层气发育具有“大而贫”的特征，与前两者比，其煤层气开发潜力明显较差。

COMPARISON OF GEOLOGY AND CBM DEVELOPMENT POTENTIAL OF THREE COAL BASINS IN RUSSIA,UKRAINE AND KAZAKHSTAN

Russia, Ukraine and Kazakhstan are rich in coal and coalbed methane (CBM) resources. Under the direction of the success in commercially developing CBM in America, those three countries are gradually conducting exploration and development of CBM in their own counties. Based on the structure, stratigraphy and CBM geology of three coal basins (Kuznetsk Coal Basin, Donets Coal Basin and Karaganda Coal Basin) in those countries, this paper analyzes and compares in detail the development potentials of the three coal basins, and the results show that the CBM resources in Kuznetsk Coal Basin is characterized by very tremendous resources and very high density, which is favorable for large scale CBM development; the CBM resources in Karaganda Coal Basin is characterized by small resources but high density, which is also suitable for CBM development; but the CBM resources in Donets Coal Basin is characterized by great resources but low density, which is obviously less favorable for CBM development.
