应用稳定联同位素、饱和烃色谱及色质等资料对巴参1井下白垩统河口组（K1h）中部原油及其对应层位和下伏各层段生油岩进行了分析对比，指出了该段原油与珠罗统窑街组（J2y）生油岩有较好的亲缘关系，回答了远离中侏罗统生油岩原油的来源问题，这对于认识民和盆地生储盖组合特征、油气运移和聚集规模具有重要意义
Based on the data of stable isotopes, chromatographic and chromatographic characteristics of saturated hydrocarbons, the crude oil in the lower Cretaceous Estuary Formation (K1h) of Paqinseng 1 and its corresponding strata and the underlying source rocks of the underlying layers are analyzed and compared. It is pointed out that this section The crude oil has a good genetic relationship with the J2y source rock and answers the origin of the crude oil far away from the Middle Jurassic source rocks. This is of great significance in understanding the characteristics of the reservoir-cap combination, the hydrocarbon migration and Aggregation is of great significance
