【摘要】：為了明確鄂爾多斯盆地旬邑探區(qū)三疊系不同層位烴源巖的生烴潛力及延長組油藏油-源等地質(zhì)問題,針對旬邑探區(qū)三疊系延長組是否存在有效烴源巖及石油來源的爭議,應(yīng)用有機巖石學(xué)和地球化學(xué)對探區(qū)內(nèi)的烴源巖及原油樣品進行了分析。結(jié)果表明,探區(qū)延長組長7烴源巖干酪根類型主要為Ⅰ型和Ⅱ型,其次為Ⅲ型,有機質(zhì)成熟度中等,為好烴源巖。通過油-油及油-源樣品對比分析,認為長6原油、長8原油與長7烴源巖具有相似的沉積環(huán)境與成熟度,均為成熟油,其沉積環(huán)境為淡水、弱氧化還原環(huán)境;生油母質(zhì)類型具有以藻類生源為主的混合型特征。旬邑探區(qū)長7烴源巖對長6和長8油藏的形成具有一定的貢獻。
[Abstract]:In order to clarify the hydrocarbon generation potential of different Triassic source rocks in Xunyi exploration area, Ordos Basin and oil-source oil source of Yanchang formation, this paper aims at the controversy on whether effective source rocks and oil sources exist in the Triassic Yanchang formation in Xunyi exploration area, Ordos Basin. The source rocks and crude oil samples in the exploration area were analyzed by organic petrology and geochemistry. The results show that the kerogen types of source rocks in Yanchang area are mainly type 鈪，
