本文运用有机地球化学测试手段，对东柏各庄凸起侏罗系烃源岩（泥岩、煤）氯仿抽提物的烃类组成进行了系统剖析，揭示其具有煤系地层的地化特征，系成熟的烃源岩，在饱和烃镏分中发现－不常见的苯基烷烃化合物系列，可能系微生物藻类成因．
This paper systematically analyzes the hydrocarbon composition of the Jurassic hydrocarbon source rock (mudstone and coal) of Dongbagezhuang raised by organic geochemical test, revealing that it has the geochemical characteristics of coal-bearing strata, A well-developed source rock, found in saturated hydrocarbons - an uncommon series of phenyl alkane compounds that may be responsible for microbial algal origin.
