Nonhydrocarbons(非烃) are compounds of oxygen, sulfur, nitrogen of alkanes(是胶质、沥青质的主要成分)。
Physical properties of the reservoir fluids are different from those of the fluids at the surface.
随油藏的开采→地下流体的相态发生变化→影 响最终采收率。为合理开发油藏,就必需搞清地 下流体的相态、物性随压力的变化。

第一章油藏流体的物理性质
油层(formation):能储集油气、并能让油气在 其中流动的多孔介质。
油藏:深埋在地下的油气聚集的场所。 单一圈闭、统一的水动力系统、统一的油水界面。
Reservoir(油藏) is a porous and permeable
