| 摘 要： | 油气储集岩中不同孔隙类型（开放型与封闭型）中的油气组分、孔隙中自由状态的油气组分、矿物颗粒表面吸附（束缚状态）的油气组分、以及矿物内部油气包裹体之间常规生物标志化合物组成（甾、萜分布）存在明显的差异，反映了不同成藏阶段油气组成的地球化学特征，展示了油气充填过程，同时为油源对比提供了新方法。

| Abstract: | Distinct compositional varaitions exist among hydrocarbons in open pores,colsed pores and bydrocarbon inclusions hosted in minerals of reservoir rocks.In a pore scale,those heterogeneities are also indicated between free hydrocarbons and absorbed hydrocarbons by various minerals,reflecting compositional changes of hydrocarbons in reservoirs during hydrocarbon filling process.Analysis of those various hydrocarbons in reservoir rocks could provide imporant infor mation for oil source correlations. |

| Keywords: | hydrocarbon reservoirs hydrocarbons in closed pores free hydrocarbons absorbed hydrocarbons hydrocarbon inclusions oil source rock correlation |
