| 摘 要： | 通过大量的岩心观察以及薄片鉴定,并以此为基础对该区储层岩石学特征进行了深入的研究。研究结果表明姬塬地区长2地层储层岩性以细粒长石砂岩和岩屑长石砂岩为主,储集砂岩的主要胶结物有高岭石、绿泥石、铁方解石及硅质,次为伊利石、铁白云石、方解石及长石质,姬塬地区长2砂岩分选中-好、次棱角状,以薄膜-孔隙及孔隙式胶结为主。 |
| 关 键 词： | 姬嫄地区 岩石学特征 砂岩碎屑组分 胶结物 结构特征 |

| Abstract: | Based on core observation and rock slice identification,rock characteristics of the reservoir were studied.The results show that main lithospheric types of Chang 2 oil-bearing formation in Jiyuan area are fine-grained feldspar sandstone and lithic feldspar sandstone;Main cements of the reservoir sandstone are kaolinite,chlorite,iron calcite and silica,followed by the illite,iron dolomite,calcite and feldspar.The sandstone of Jiyuandi Chang 2 formation is well and angular shape,has film pore and pore cementa... |
