Abstract

近年来,中国页岩气研究和工业化生产获得极大发展,丰富了中国天然气地质学理论和增加了国内天然气生产供应。今后页岩气在中国天然气工业中要上更大台阶,研究解决以下4个地质和地球化学问题意义重大:①中国要突破当前单一的经济页岩气层组。美国已在29个盆地发现至少30套经济页岩气层组,但中国仅有一个盆地(四川盆地)发现1套经济页岩气层组(五峰组—龙马溪组),需要突破当前单一层组。②经济页岩气层组的 区间值及气田的 段值。中国经济页岩气层组的 区间值为3.31%,气田的 段值为2.34%,两值均较小;美国的气层组 区间值为4.1%,气田 段值为3.5%,两值均较大。美国一些腐泥型页岩气田发现在 值为1.0%~1.3%的生油窗高阶段内,中国要注意处于该段值中的页岩气田勘探;同时要开辟煤系泥页岩气勘探。③气田的持续高产期。世界首个商业化开发的页岩气大气田(Barnett)实际生产显示,年产量达100×10 m的高产期预测约为20年。中国页岩气田开发尚处在建产阶段。④断裂在页岩气保存与开发中的作用。断裂对页岩气的富集与否具双重性。美国页岩气盆地构造稳定而断裂较少,而中国页岩气盆地构造活跃且断裂发育。总体上断裂对中国页岩气弊大于利,断裂使连续分布的五峰组—龙马溪组碎块化,限制了气田面积。

Recently, shale gas research and industrial production in China have been greatly developed, which has enriched the theory of natural gas geology in China and increased the supply of domestic natural gas production. In the future, shale gas will obtain great achievements among the developments of natural gas industry in China. The following four geological and geochemical issues about the exploration and research of shale gas has great
