海拉尔盆地煤层气资源评价及潜力分析
|
摘要
利用钻井和地震资料 ,评价和预测了海拉尔盆地煤层的发育和分布 ,结合煤层含气量参数 ,预测了盆地内的煤层气资源前景。结果表明 ,海拉尔盆地的煤层气资源量约为 10 .79× 10 11m3 ,其中呼和湖凹陷约为 7.4 3× 10 11m3 ,这远远超过了前人对整个东北区煤层气资源的评价。这表明 ,如果考虑煤层有一定埋深的含油气盆地 ,东北区的煤层气资源潜力还有相当大的增长空间。与美国已进行过成功煤层气勘探开发的含煤盆地对比表明 ,海拉尔盆地 ,尤其是呼和湖凹陷的煤层气潜力值得重视。
Using the well and seismic data,the occurrence and distribution of coal beds in Hailar Basin are evaluated and predicted in this paper.Combined with parameters of gas content,the resource prospect of coalbed gas is evaluated.The results indicated that the amount of coalbed gas resource of Hailar Basin is about 10.79×10 11 m 3 and is far more greater than that of the whole northeastern China evaluated by precursor.It is suggested that the resource potential of coalbed gas in northeast China has greater increasing space if considering the oil and gas bearing basins where the coal bed has been buried relatively deep.The comparison with American coal bearing basins where the coalbed gas has been exploited successfully shows that the resource potential of Hailar Basin,especially the Huhehu depression,is worth of recognition.
