Sulfid also can be regarded as a marker of the action of sulfur bacteria . 8 ) based on research results , author postulated that early generation of hydrocarbons is closely related to the action of sulfur bacteria . many kind of algae such as dinoflagellates , diatom , prynesiophytes etc have rich biological lipids which has lower polymerization 6 、从未熟一低熟源岩生烃组分及其演化、可溶有机质转化生烃等方面，探讨了未熟一低熟油的形成机制，提出本区未熟一低熟油气的形成是低活化能的富氢腐泥组分受到硫细菌早期低温降解作用的结果。
2.
We can see that es3 and es4 source rocks contributes greatly to the formation of immature oil . other oil source correlation also show that the immature oil originated from source rocks of es3 and es4 in this region . 7 ) the existence of high abundance of sulfid in the mudstone indicate that that there is a relatively high salinity environment in source rocks which is favorable for algae growth 4 、通过稳定碳同位素、甾烷和萜烷等不同的生物标志化合物参数分析探讨了研究区德1井低熟油的物源，生物标志化合物图谱指纹对比表明，德1井沙一段( es _ 1 )油来源于本段烃源岩，德1井沙四段( es _ 4 )原油主要来源于沙四段泥岩和沙三段中、下部泥岩，为自生自储成因。
