摘要
This paper has taken the sedimentology, petrology and stratigraphy as the main research means. Having summarized the sedimentary systems and sedimentary facies of Late Paleozoic, the paper analyzed the physical characteristics of the sandstone reservoir in Shanxi Formation, Shihezi Formation and so on. Study showed that there are four sedimentary systems. Among which, the distributary channel sand body of delta, the sedimentary sand body in the large river, lake and lake-delta are the favorable reservoir of coal-formed gas. The main rock types of the reservoir are the feldspar sandstone, quartz sandstone, lithic sandstone and the hard sandstone.
