摘要

根据M ango提出的稳态催化轻烃成因模式,2,4-二甲戊烷/2,3-二甲基戊烷值是一项纯温度参数,Bem ent和M ango等建立了该轻烃温度参数与埋深温度的函数关系式,用于原油生成温度计算,为定量研究原油成熟度提供了新思路。以苏丹M elut盆地为例,计算了原油的生成温度,计算结果表明,其3区和7区原油成熟度最低,4区原油成熟度最高,而6区原油成熟度位于二者之间。

Abstract

 According to the steady-state catalytic model for the origin of light hydrocarb on proposed by Mango, 2,4-/2,3-dimethylpentane ratio is a pure temperature par ameter. Bement and Mango et al. established the functional equation between the  light hydrocarbon temperature parameter and the burial temperature and applied i t to the calculation of hydrocarbon-generating temperature, which provide a new  choice for oil maturity research. In this paper, the generating temperature of  hydrocarbons from the Melut Basin are calculated, the result indicate that oil m aturity in the block 3 and 7 is the lowest, the block 4 is the highest, and the  block 6 is in the middle. 
