【摘要】：渤海灣盆地濟(jì)陽(yáng)坳陷青東凹陷存在常規(guī)原油和生物降解油。選取新參數(shù)β-胡蘿卜烷/(2×C_(29)藿烷)、伽馬蠟烷/(2×C_(29)藿烷),三環(huán)萜烷系列參數(shù)(2×C_(24)四環(huán)萜烷)/(C_(26)三環(huán)萜烷)、(2×C_(19))/(C_(28)+C_(29))三環(huán)萜烷以及?/菲,結(jié)合C_(29) 4-甲基甾烷及碳同位素特征等,將該區(qū)原油劃分為Ⅰ、Ⅱ、Ⅲ和Ⅳ等4類(lèi),烴源巖劃分為A、B_1和B_2等3類(lèi)。Ⅰ類(lèi)原油來(lái)自青東凹陷中北部深洼的沙三下亞段成熟烴源巖,Ⅱ類(lèi)原油來(lái)自凹陷南部沙四上亞段烴源巖,Ⅲ類(lèi)原油來(lái)自中北部洼陷的沙四上亞段烴源巖,Ⅳ類(lèi)原油來(lái)自青南洼陷沙四上亞段烴源巖,而青東8井原油應(yīng)有青東凹陷南部烴源巖的貢獻(xiàn)。

A new parameter, 尾 -carrodane / 2 脳 Che / C _ (29) cariane, gamma-paraffin / _ 2 脳 C ~ (29) hopane, tricyclic terpene, tricyclic terpene (2 脳 C ~ (+) C ~ (+) ~ (24) ~ (2 脳 C ~ (19) P / C ~ (28) C ~ (29) C ~ (29) C ~ (29), etc.) trichloroterpene and its / phenanthrene, combined with C _ (29) _ (4) -methylsterane and carbon isotopic characteristics, are selected. The crude oil in this area is divided into four types, I. e., 鈪，
