Abstract: By comparing characteristics of quartz sandstone reservoir of the Neopaleozoic of Yulin gas field with Sulige gas field in Ordos Basin, it is indicated that the Shan 2 Member quartz sandstone reservoir of the Yulin gas field is the low porosity and relatively high permeable reservoir while the He 8 Member quartz sandstone reservoir of the Sulige gas field is the high porosity and relatively low permeable reservoir,respectively. And based on analyzing of material source,depositional condition and diagenesis, and so on,of the two types quartz sandstones,it is suggested that the reservoir characteristics of Shan 2 member of Yulin gas field is formed by the alteration due to the sea water in depositional stage and diagenesis in the later stage,while He 8 member of Sulige gas field is the result of high content of matrix and diagenesis in the later stage.
