摘要:

页岩气实验地质评价技术进步是美国页岩气勘探开发成功的关键要素之一。从页岩的含气性、赋存性和可压性三个方面,总结了页岩气实验地质评价技术方面所取得的进展,重点介绍针对中国南方海相页岩热演化程度高的特征,开发的超显微有机岩石学、地层孔隙热压生—排烃模拟及孔隙表征等技术,探讨了页岩气实验地质评价技术未来发展方向,指出多尺度孔隙结构有效性及连通性、成岩演化过程中有机—无机孔协同表征、可压性动态评价是页岩气地质评价技术的关键攻关方向。

Abstract:

The improvement of experimental technologies of geological evaluation for shale gas is the key factor for the success of shale gas exploration and development in America. The progress in experimental technologies of geological evaluation of shale gas is summarized from three aspects including gas-bearing property, occurrence and fracability of shale. It mainly focuses on the ultramicroscopic organic petrology, formation porosity thermocompression simulation experiment of hydrocarbon generation and expulsion, and the characterization of pore network, which are developed for high thermal maturity marine shale of South China in recent years. The future trends of experimental technologies of geological evaluation for shale gas are discussed. It is proposed that the effectiveness and connectivity of multiscale pore structure, the characterization of organic and inorganic pore in diagenetic evolution, and dynamic evaluation for fracability are the key studying aspects in experimental technologies of geological evaluation of shale gas.

Key words: shale gas, geological evaluation, experimental technologies, research progress
