摘要：

本区安山岩含油饱和度仅12.5%,砾岩仅23.4%,但出纯油。作者认为,目前室内测定的储层孔隙度为连通孔隙度,连通孔隙可分为非流动孔隙与流动孔隙两部分,出纯油与否取决于流动孔喉系统含油饱和度的高低。

Abstract:

In Alxa Region,Eran Basin,oil saturation is as low as 12.5% for andesiteand 23.4% for conglomerate,but pure oil is produced in oiltesting.Theauthors suggest that the productivity of pure oil depends on the oil satura-tion of flowing pore space but not that of availible pore space.
