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.
