中文摘要：
通过对鄂尔多斯盆地上古生界榆林气田和苏里格气田石英砂岩储层特征的对比，指出榆林气田山2段石英砂岩储层属于相对低孔高渗型储层，苏里格气田盒8段石英砂岩储层属于相对高孔低渗型储层；通过分析两类石英砂岩的物源、沉积条件和成岩作用等因素，认为沉积期海水改造及后期成岩作用形成了榆林气田山2段储层的低孔高渗，而沉积时的高杂基含量与后期成岩共同作用形成了苏里格气田盒8段储层的高孔低渗。
英文摘要：
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 Ynlin 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 Shah 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.
