Micro-structure analysis of mudstones in the Middle Permian Zhesi Formation in Solun area, Inner Mongolia

Oil and Gas Resources Survey Center, China Geological Survey Bureau, Beijing 100029, China

摘要

摘要: 在野外地质露头实测、系统取样和综合分析测试的基础上，对松辽西部外围内蒙古索伦地区上古生界二叠系哲斯组暗色泥岩的地球化学特征与微孔隙特征进行了研究。结果表明，哲斯组泥岩微孔隙主要包括微孔（粒间孔、粒内孔、有机质孔）和微裂缝（矿物层间缝、有机质与矿物间缝、有机质内裂缝）。进一步的微孔隙发育特征和成因分析得出，哲斯组泥岩有机质孔相对不发育的特征主要与TOC含量偏低及较强压实作用下的有机质孔塌陷作用有关，而泥岩微裂缝的发育主要与其脆性矿物含量较高有关。综合烃源岩与储集特征分析，索伦地区哲斯组泥岩具备了页岩气远景区的条件，寻找TOC含量高的富有机质泥页岩发育区是今后该区乃至东北地区上古生界页岩气勘探的关键。

Abstract: The geochemical characteristics and micro-structure of dark mudstones from the Middle Permian Zhesi Formation in Solun area, Inner Mongolia were studied using field outcrops, samplings, and systematic analyses. Micro-pores (including interparticle, intraparticle and organic pores) and micro-fractures (including interlayer fractures in minerals, fractures between organic matter and minerals, and fractures in organic matter) developed in mudstones in the Zhesi Formation. Organic pores were not well developed in the Zhesi mudstones, mainly due to low TOC content and pore collapse under strong compaction effect. Micro-fractures were well developed thanks to high brittle mineral content. The characteristics of source rocks and reservoirs showed that mudstones in the Zhesi Formation have a good prospect for shale gas exploration. The areas with widespread mudstones rich in organic matter are targets for shale gas in the Upper Paleozoic in Northeast China.
