| 摘 要： | 北山盆地群侏罗系和下白垩统砂岩储层主要属长石岩屑砂岩和岩屑长石砂岩，其次为岩屑砂岩，成分和结构成熟度均较低；储层孔隙类型以次生孔隙为主，孔隙结构及物性总体较差。储层分类评价及综合分析表明，中侏罗统储层属较有利储层，在北山盆地群具有较重要的储集意义。

| Abstract: | Reservoir rock of Jurassic and lower Cretaceous in Beishan Basin group is mainly feldspathic litharenite and lithic arkose,Secondly is lithic sandstone,Both mineral and textural maturity are poor.Main pore type in the resevoirs is secondary porosity,Neither pore texture nor physical property are good in all.It is showed that middle Jurassic reservoir belongs to better one,and may be more significant for oil reserving in these basins. |

| Keywords: | reservoir sandstone Jurassic lower Cretaceous evaluation Beishan Basin group |
