【摘要】：對臨南洼陷古近系火山巖油藏中12個原油樣品進行芳烴生物標志物分析,結果表明:芳烴中三環(huán)、四環(huán)芳烴化合物占優(yōu)勢,三芳甾烷含量較高,二環(huán)、五環(huán)、NSO雜環(huán)芳烴化合物含量較低。二環(huán)芳烴參數(shù)(TDE_1、TDE_2、TDE_3)指示典型的湖相、源自年輕源巖的原油特征。三環(huán)芳烴以菲系列化合物占主導,檢出少量惹烯,表明原油是以低等水生生物為主要生源,有少許高等植物貢獻。五環(huán)芳烴中芘、苯并芘豐富,側證了低等水生生物的優(yōu)勢輸入。NSO雜環(huán)芳烴中含量占絕對優(yōu)勢的硫芴反映出源巖沉積于較強的還原環(huán)境。二環(huán)芳烴成熟度參數(shù)(DNR_1、TNR_2,)、三環(huán)芳烴成熟度參數(shù)(MPI_1、F_1和F_2)、含硫芳烴成熟度參數(shù)(MDR)、三芳甾烷成熟度參數(shù)C_(28)-TAS 20S/(20R+20S)均一致顯示原油處于成熟—高成熟階段。
[Abstract]:The aromatics biomarkers of 12 crude oil samples from Paleogene volcanic reservoirs in Linnan sag were analyzed. The results showed that the aromatics were mainly tricyclic, tetracyclic aromatics, triarosterane, and bicyclic. The content of NSO heterocyclic aromatic compounds is low. The PAHs parameter TDE1 / TDE2 / TDES3) indicates the typical lacustrine facies derived from the crude oil characteristics of the young source rocks. Tricyclic aromatic hydrocarbons are dominated by phenanthrene series compounds, and a small amount of yakene is detected, which indicates that crude oil is mainly derived from low aquatic organisms and has a little contribution from higher plants. Pyrene and benzopyrene are abundant in pentacyclic aromatics. The dominant input of low aquatic organisms. Sulfur fluorene, which is the dominant content in NSO heterocyclic aromatics, reflects that the source rocks are deposited in a strong reduction environment. The maturity parameters of dicyclic aromatic hydrocarbons (DNRS) and TNR2s, tricyclic aromatic hydrocarbons (PAHs), MPI-1 / FST1 and F2s, sulfur containing aromatics (C_(28)-TAS 20S/(20R) and triarosteranes (C_(28)-TAS 20S/(20R 20s) all show that the crude oils are in the mature-high maturity stage.
