山西沁水盆地柿庄北地区煤层气潜力
|
摘要
本文是在二维地震和煤层气参数井勘探成果的基础上,对沁水盆地柿庄北区块的石炭-二叠系煤系地层进行了广泛的评价。地质背景调查与煤储层分析结果表明该地区具有地质构造简单、煤层发育稳定、煤层气含气量高而饱和度适中的特点。根据本次工作所确定的煤层气估算资源量为402.93亿m3,并通过对本区以往勘探成果的阐释,从而有助于确定该地区煤层气资源的商业开采潜力。
This paper has completed an extensive evaluation of the Permian-Carboniferous coal seams of the Shizhuang North block in Qinshui basin,which included the 2D seismic and the appraisal CBM wells. As the technical report documenting geological setting and the coal reservoir analysis,it has a low relief geo-structure,well developed coal seams and a high gas content coal with a medium saturation of this area. This work has quantified an estimated 40.293 billion m3 of CBM gas in place which is helpful to determine the CBM potential for commercial development with the geologic sarvey camied out in the past.
