砂岩沥青 [shā yán lì qīng]
sandstone rock asphalt
- 摘要文章对龙门山北段震旦系－侏罗系的岩性特徵、有机质丰度、有机质类型、氯仿沥青"A"含量、族组成、有机质成熟度、生物标志化合物等地化特徵进行了论述，指出龙门山北段上三叠统、上二叠统、下二叠统、下寒武统以及震旦系是主要的烃源岩层系；探讨了龙门山北段的油气成藏模式：震旦系－石炭系的油气来源于下寒武统和震旦系；二叠系的油气源于其自身；三叠系有其自身的油气，也有来自于二叠系的油气；厚垻油砂岩中的油、江油渔洞梁飞仙关组的油以及矿山梁沥青脉有共同的油气来源。
On the basis of expounding the geochemical characteristics as lithological feature, organic matter abundance and type, chloroform bitumen "A" content, group composition, organic matter maturity and biomarker, etc., of Sinian-Jurassic in the north section of Longmen Mountains, it is pointed out in the paper that the principal series of strata of hydrocarbon source rocks are Sinian, Lower Cambrian, Lower Permian, Upper Permian and Upper Triassic in this region; the oil and gas in Sinian-Carboniferous came from Sinian and Cambrian; those in Permian from itself; those in Triassic not only from itself but also from Permian; and the oil in Houba sandstone and in Feixianguan Formation at Yudongliang in Jiangyou and the bituminous veins at Kuangshanliang are of the same hydrocarbon source.
