摘　　要：应用"活力论"原理研究"活性分子"在有机质成烃过程中的作用。首先阐明了烃源岩的粘土矿物晶格水和粘土矿物集合体间的层间水的水分子性质及其演变过程,然后叙述了水"活性分子"形成质子酸束(H+)的原理和机制及其在可溶性有机质成烃过程中的加氢脱水作用和加氢脱羧酸成烃作用:探讨了水"活性分子"的质子酸束对大分子干酪根轰击的"多代链式反应"的裂解成烃过程及其烃类产物的性质与组成;最后解释了生物标志化合物胆甾垸的立体同分异构体不同深度丰度变化的原因。The principle of activated energy theory is applied to examine the effect of active molecule in process of organic matter hydrocarbon generation. First of all, the properties and evolvements of lattice water of clay minerals in source rocks and interlayer water of clay mineral aggregates are clarified. Secondly, the principle and mechanism of forming proton acid bundle (H+) from active molecule (H2O) are presented, including hydrodewater and hydrodecarboxylic acid reactions during soluble organic matter hydrocarbon generation; and the proton acid bundle of active molecule (H2O), the cracking hydrocarbon generation by multichain reaction bombarded by macromolecular kerogen and property and composition of its hydrocarbon products are discussed. Finally, the reason for stereo-isomer variation of cholestane in different depths and abundances are explained.
