有机质微观成烃和宏观成藏机理

从近代物理学的角度, 提出了有机质成烃是一个“混沌”领域。应用拉格朗日( Lagrange) 函数阐明了微观与宏观的概念在有机质成烃和成藏中的科学内涵; 根据量子力学的价键理论解释了质子酸束在碰撞干酪根裂解过程中的顺序和方式; 以键结合能理论和热力学内能是体系内蕴含的一切能的总和为依据, 导出了干酪根裂解释放能的表达式; 从动态的微观成烃和宏观成藏的观点出发, 应用热力学卡诺(Carnot) 循环的热功转换理论, 探讨了油气呈脉动式的膨胀和压缩的“蠕动渗流”形式作初次运移; 叙述了凹陷深部热功转换所释放的能量分别为封闭层提供热源和油气二次运移提供压力梯度。剖析了从微观成烃到宏观成藏各层次的性质和特征。

Mechanisms of Micro Hydrocarbon Generation and Macro Hydrocarbon Accumulation from Organic Matter

In this paper, that organic matter-generated hydrocarbon is a chaos domain is presented as viewed from modern physics; the scientific intension of concept of micro and macro applied to hydrocarbon generation and accumulation from organic matter is enucleated in terms of Lagrange function; the sequence and the mode in which the proton bundles impact the kerogen cracking in terms of valence bond theory of quantum mechanics are explained; an expression for energy release from kerogen cracking on the basis of binding energy of chemical bonds and thermodynamics energy that is the total of all energy in the system is derived; the primary migration of hydrocarbon in forms of creeping flow under expansion and compression is discussed by using the work-heat transformation theory of Carnot's circular thermodynamics; the abnormal temperature and pressure generated and accumulated in deep sag during the work-heat transformation are described, which provide the heat sources for seal zones and the pressure gradient for secondary hydrocarbon migration, respectively. Finally, the properties and characteristics of the micro hydrocarbon generation and the macro hydrocarbon accumulation are analyzed in detail.
