Abstract Great breakthrough has been made in the exploration of lacustrine shale gas in China, but little research on reservoir of salt-water lacustrine shale was carried out. Organic geochemical analysis,mineral composition analysis and pore structure analysis of reservoir of the Palaeogene Xiaganchaigou Formation lacustrine shale in western Qaidam Basin has been done by the authors. (1)The organic content has intense heterogeneity in the 0.12％～1.35％ range,the content of chloroform bitumen “A”is high and the organic matter is mainly of type Ⅱ.(2)The content of carbonate is the highest with an average of 27.8％,and then clay minerals and quartz. There are 38.2％ of the samples have anhydrite,which reflects the typical salt￣water lacustrine environments. (3) The organic matter micro-pores observed in the SEM are less developed,the shape is irregular and pore size is large. Intergranular pores are mainly micronl￣sized in diameter, while micro-fractures are mainly less than 1μm in width. Mesopores have most of specific surface area and pore volume of shale pores,and are main places for gas adsorption and storage. The chloroform bitumen“A”influenced the pore structure of the samples. (4)The content of clay minerals is low and brittle minerals is high in research area,which is comparable with the series of gas-containing shales in U.S. and with the Lower Paleozoic shale in the Sichuan Basin,are conducive to creating cracks,and are easy for fracturing.
