| 摘 要： | 内蒙古巴彦浩特盆地广泛发育上石炭统太原组煤系烃源岩.在野外地质勘查、典型剖面实测、样品采集及实验分析基础上，开展了有机质丰度、有机质类型、有机质成熟度等有机地球化学特征分析与研究，初步对其生烃潜力进行评价.结果表明：太原组烃源岩有机质丰度高，热演化程度属于成熟—高成熟演化阶段，具备较好的页岩气气源条件.通过多因素叠加分析的方法，圈定了页岩气成藏有利区3处，分别是北部的查干布拉格有利区、通古勒格淖尔嘎查－伊克尔嘎查苏木有利区和南部的下河沿－营盘水有利区.

| Abstract: | The coal-bearing source rocks of Upper Carboniferous Taiyuan Formation are widely developed in Bayan Hot Basin of Inner Mongolia. Based on the geological exploration, typical section survey, sampling and experimental analysis, the paper carries out study on the organic geochemical characteristics including organic matter abundance, types and maturity and makes preliminary evaluation on the hydrocarbon potential. The results show that the organic matter of source rocks has good shale gas source conditions with high abundance, the thermal evolution belonging to maturity-high maturity stage. Three favorable areas of shale gas reservoir are selected by multi-factor overlay analysis, namely the northern Chaganbulage, Tonggulegenaoergacha-Yikeergacha and southern Xiaheyan-Yingpanshui areas. |
