石油,是各种烃和非烃化合物的复杂的混合物,是由有机母质在地质-地化因素作用下转变而成的。因此,石油组分必定能反映它的地质历史过程。所谓石油的“生物标志”是指继承自“生物前身”的残余烃,即化学化石。为探讨苏联各个地区的这种烃,研究了长链正烷烃、结构对称的异烷烃、异戊间二烯类化合物和多环环烷烃的组分和分
Petroleum, a complex mixture of hydrocarbons and non-hydrocarbon compounds, is formed by the transformation of organic parent materials under the influence of geo-geochemical factors. Therefore, the petroleum component must reflect its geological history. The so-called petroleum “biomarker” refers to the residual hydrocarbon inherited from the “biological predecessor”, namely chemical fossils. In order to explore this kind of hydrocarbons in various parts of the Soviet Union, we studied the components and fractions of long-chain n-alkanes, symmetrical isoparaffins, isoprenoids and polycyclic naphthenes
