俄罗斯含煤盆地煤层气开发潜力分析与评价

Analysis and Evaluation on Development Potential of Coalbed Methane of Coal Basin in Russia

  • 摘要: 基于通古斯盆地、勒拿盆地、库兹涅茨克盆地和伯朝拉盆地的构造特征、煤系地层及煤层发育特征、煤储层特征、煤及煤层气资源量的分析,从物质基础、生气条件和保存条件方面对比评价该4个盆地的煤层气开发潜力。评价表明:库兹涅茨克盆地煤层气资源丰度达7.16×108m3/km2,煤层总厚度大且含气量高,储层渗透率高达0.15μm2,开发潜力最大;伯朝拉盆地煤层气资源在沃尔库塔市附近高度富集,占盆地总资源量的30%,开发潜力较大;通古斯盆地煤层气资源量高达2.299×1012m3,但勘探程度低,开发潜力中等;勒拿盆地煤层气资源丰度最低,开发潜力最小。

     

    Abstract: The characteristics of tectonic, coal and coal- bearing strata, coal and coalbed methane resource extent of Tunguska Basin, Lena Basin, Kuznetsk Basin and Pechora Basin in Russia were analyzed. Combining the results from the analysis, coalbed methane development potential of the four basins were evaluated from th ree aspects, material base, gas generation conditions and preservation conditions. The evaluation results show that Kuznetsk Basin is characterized for thick coal seam s and high gas content. The coalbed methane resource densityis 7.16 x 108m3/km2. The permeability of coal is as high as 0.15 μm2. It is much favorable for coalbed methane development. The coalbed methane resource abundance is very high around Vorkuta in Pechora Basin. 30% of total resource extent was found in Vorkuta. As a result, Pechora Basin is favorable for coalbed methane development. The coalbed methane resource extent of Tunguska Basin is 2. 299 x1012m3, but only a lttle res ource extent has been proved. Tunguska Basin is suitable for CBM development while Lena Basin is unfavorable for CBM development due to low CBM resource abund ance.
