摘　　要：依据钻井、测井和测试资料,对宁武盆地太1段页岩的埋深、厚度、有机质丰度、有机质成熟度、含气量等页岩气富集关键地质因素进行了系统研究。研究表明:宁武盆地太1段页岩埋深由北向南逐渐增大,页岩厚度存在3个高值区,有机质丰度中等,有机质成熟度处于成熟阶段,含气量整体偏低。在此基础上确定了太1段页岩气有利区优选指标的临界值,优选出窑子头南部和静乐县南部2个页岩气有利区。Based on the drilling,logging and measured data,the key geological factors such as the burial depth,thickness,organic matter abundance,organic matter maturity,and gas content of shale in Tai 1 member of Ningwu basin were systematically studied.The results show that the burial depth of the shale in Tai 1member increases from north to south.The shale thickness exists three high-value'areas.The organic,matter abundance is medium,and the organic matter is mature.Howerver,the gas content is low. Based on these,the critical values of the evaluation index for favorable area of Tai 1member shale gas were determined,and two favorable areas for the shale gas were selected:south of Yaozitou and south of Jingle.
