| 摘 要： | 从烃源岩特征、天然气组分、油气碳同位素、凝析油全烃和轻烃、储层沥青等方面对营山地区上三叠统和中、下侏罗统油气源特征进行了对比研究,阐明了营山地区上三叠统须家河组和中、下侏罗统油气的地球化学特征、成因和可能来源。研究表明营山地区上三叠统须家河组油气主要来自须家河组自身的煤系烃源岩,天然气以成熟腐殖型母质成因为主,而中、下侏罗统气藏产出的油气主要来自其自身的烃源岩。营山地区构造活动强烈,断层发育,使得部分井区中、下侏罗统产出的天然气特征与下伏产层极为相似,反映了断层对该井区附近的各层段有一定的沟通作用。中、下侏罗统地层在部分井区可能有上三叠统须家河组油气的侵入,须家河组烃源岩对中、下侏罗统油气成藏有一定贡献作用。 |
| 关 键 词： | 上三叠统 中、下侏罗统 油气源特征对比 营山地区 |

| Abstract: | The geochemical features,genesis,and possible source of Xujiahe Formation of Upper Triassic and Middle to Lower Jurassic,Yingshan area,is revealed by comparison on their oil-gas source characteristics,such as characteristics of source rocks,gas composition,carbon isotope,whole hydrocarbon,light hydrocarbon and reservoir bitumen.The oil-gas of Xujiahe Formation is mainly comes from autogenic coal source rocks,and the natural gas from Xujiahe Formation is mainly mature humic parent material genesis,whereas oil-gas from middle to lower Jurassic gas reservoir is mainly from it＇s own source rocks.The similar characteristics of gas from partial well field of middle to lower Jurassic and underlying pay formation is explained by the channels among those pay formations formed by intense active faults of Yingshan area.Partial well field of middle to lower Jurassic stratums maybe invade by oil-gas from Xujiahe Formation of Upper Triassic,which mains the source rocks of Xujiahe Formation have some contribution for Middle to Lower Jurassic reservoirs. |
| Keywords: | Upper Triassic Middle to Lower Jurassic oil-gas source features comparison Yingshan area |
