【摘要】 本文以野外地质踏勘和地质资料综合研究为手段,对北京地区的页岩气资源前景进行了分析,并初步估算了北京地区的页岩气资源潜力。研究表明,北京地区发育海相青白口系下马岭组、海陆交互相石炭—二叠系和陆相侏罗系窑坡组三套分布规模较大的泥页岩地层,分布面积约6750km2;泥页岩中有机质含量高,具有形成页岩气藏的条件,且富含有机质泥页岩厚度较大,埋藏深度适中,连续性较好,具有一定的页岩气资源潜力。利用丰度类比法估算,北京地区页岩气潜在资源量约1.16~2.34万亿m3,预测潜在可采资源量约1160~2340亿m3。更多还原

【Abstract】 Based on wild study and geological data analysis, this paper analyzes the prospect of the shale gas in Beijing area, and preliminary estimates the resources potential of the shale gas in Beijing area. There are three sets of large-scale shale strata such as marine Xiamaling Fm(Qb), marine- terrigenous rocks(C— P)and land-facies Yaopo Fm(J) in Beijing area, which distribution area is about 6750km2. The content of organic substance of the shale is high, so it has the conditions to form shale gas reservoir. The shale which contains organic matter is very thick, and the burial depth is modest, so it has the shale gas resources potential. Through the abundance analogy methods, it is estimated that the potential quantity of resource of shale gas in Beijing area is about 1.16×108~2.34 × 108m3, and the potential recoverable quantity of resource is about 116×109~234×109m3.更多还原
