中文摘要：

随着页岩储层研究的不断深入，取得了一系列重要进展和认识，主要体现在对页岩储层孔隙空间类型、储层物性控制因素以及页岩气预测与评价3方面。主要的认识有：①页岩储层中的纳米孔隙及微裂缝是重要的储集空间；②矿物组成是影响储层储集性能及产能的重要因素，黏土矿物含量是影响页岩气吸附性及孔隙大小的主要因素，而脆性矿物可以有效改善储层物一胜并提高压裂的成功率；③有机质含量和热成熟度是影响页岩储层有机质纳米孔隙发育的关键因素；④基于页岩岩一陛精细划分，可以根据页岩储层岩性及岩相层段预测有利层段；⑤提出了利用层序地层学的方法对页岩储层进行研究的理念。这些成果和认识推动了页岩气储层研究的步伐，但仍存在许多科学难题尚未解决。

英文摘要：

Abstract： With the rapid development of theories and applications of shale gas, shale gas has gradually be- come an important part of the diversified energy structure. With the gradual and further research and un- derstanding of shale reservoirs, a series of significant progresses has been made in understanding the pore space types in shale reservoir, control factors of reservoir physical property and shale gas anticipation and evaluation. The main recognitions are： ① Nanopores and microcracks are essential storage spaces in shalereservoirs. ② Mineral composition is a considerable factor that impacts reservoir capability and deliver- ability. The content of clay mineral is the main factor affecting shale gas adsorption and pore size, while brittle mineral can effectively improve reservoir properties and the success rate of fracturing. ③ Organic matter content and thermal maturity are key factors affecting organic nanopores development in shale res- ervoirs. ④ Facies are divided to predict favorable layers according to lithology and lithofacies. ⑤ Idea of sequence stratigraphy is proposed to study shale reservoirs. All these progresses promote the research of shale gas greatly, but there are still many scientific challenges remain to be resolved.
