摘要
Mango基于2000余个不同类型原油的轻烃分析数据,发现4个异庚烷化合物组成有显著的不变性,提出一种新的轻烃成因理论——稳态催化动力学模式,以此推导出K_1、K_2、RP等一系列参数,认为,K_1和K_2值在同源的原油之间保持不变,而在不同来源原油之间有一定的差别;指出反映轻烃组成的RP受烃源岩沉积环境和干酪根类型影响。这些参数可用于原油分类和油源对比,也可作为潜在的成熟度指标。
Based on the analytical data of light hydrocarbons of over 2000 oil samples of different types, Mango discovered a remarkable composition invariance in four isoheptanes, proposed a steady-state catalytic kinetic model for the origin of light hydrocarbon, and put forward K_1, K_2 and RP parameters. The KI and K2 rations are co nstant for oils from the same source,but differ to a certain degree for oils from different sources. And RP, reflecting composition of light hydrocarbon, would be affected by the depositional environment and kerogen type of source rock. Many research results show these Mango parameters will be useful tool for oil classification and correlation studies, and potentially for oil maturity index.
