晚期生油理论认为:油气生成必须具备两个条件,一是有足够的有机质并能保存下 来;一是要有足够的热量保 证有机质转化为油气

一、烃源岩的定义 烃源岩:指富含有机质能生成并提供工业数量石油的岩石。如果只提供工业数量的天然 气,称生气母岩或气源岩。 由生油岩组成的地层叫生油层。在相同的地质背景下和一定的地史阶段中形成的生油 岩与非生油岩的组合称为生油层系

1、早期的太阳系 The Early Solar System Billions of years ago, out of a swirling mass of gas and dust, evolved a system of varied planets hurtling around a nuclear-powered star-our solar system. One of these planets, and one only, give rise to complex life forms. Over time

Atomic Structure All natural and most synthetic substances on earth are made from the ninety naturally occurring chemical elements. An atom is the smallest particle into which an element can be divided while still retaining the chemical characteristics of that element (fig 3. 1). The nucleus, at the center of the atom contains one or more particles with a positive electrical charge(protons fif and usually some particles of similar mass that have no charge(neutrons
