摘要: 通过对盐生杜氏藻的热模拟成烃研究，发现其热解产物中含有丰富的咔唑系列化合物，它包括咔唑（CZ）、甲基咔唑（MCZ）、二甲基咔唑（DMCZ）、三甲基咔唑（TMCZ）、四甲基咔唑（TeMCZ）、五甲基咔唑（PMCZ）和六甲基咔唑（HMCZ）。并且在300℃热模拟产物中咔唑系列化合物含量较高,在芳烃馏分中相对含量为30.97％，350℃时产出较低，为15.44％，而250℃时未检出此类化合物。这一方面表明嗜盐杜氏藻很可能是原油和烃源岩中咔唑类化合物的主要母源之一，另一方面表明高盐环境下这种以杜氏藻为主要生烃母质的原油可能富集咔唑类化合物，这为该环境下油源对比提供了有力依据。

Abstract: It is discovered that series of carbazole compounds, including carbazole, lmethylcarbazole, 2methylcarbazole, 3methylcarbazole, 4methylcarbazole, 5methylcarbazole, 6methylcarbazole, which are affluent in the pyrolysis product of Dunaliella Salina. The relative content of the series of carbazole compounds in the aromatic hydrocarbon fraction mounts to 30.97％ at 300℃,while it is only 15.44％ at 350℃, and it rarely occured at 250℃.
On one hand, it indicates that Dunaliella Salina is one of the primary parent materials of carbazole compounds in source rock and crude oil; On the other hand, it suggests that the crude oil derived from Dunaliella Salina is probably rich in carbazole compounds under a highlyrich salt environment, which provides strong evidence to contrast crude oil with original source rock in this environment.
