Data obtained by thin-sections analysis, cathodoluminescence emission analysis and SEM/EDX show that carbonate cements seem to be the uppermost cements composed of ferroan sparry calcite and ankerite and are distributed mostly in the depth interval of 100 m below the unconformity, with their contents increasing with the depth.
通过薄片观察、阴极发光、扫描电镜/能谱分析，认为碳酸盐胶结物是研究区砂岩最主要的胶结物成分，其主要类型为方解石和铁白云石，垂向上含量随深度增加而增加，多集中分布在白垩系和侏罗系之间的不整合面之下约100 m的范围之内。

In the temproal-spatial′distribution, its source rocks is mainly Palaeogene, secondly Cretaceous and Jurassic of Mesozoic, Triassic, having mudy rocks and coal-rich, their organic carbon being 0.2% and 0.4% respectively.
提出了过渡带气综合判识标志：时空分布上，其源岩主要为下第三系，其次为中生界白垩系和朱罗系、三叠系，以泥质和煤系有机质最丰富，有机碳丰度为0.2％、后者为0.4％。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.
第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。
