摘要
The empirical relationship between methyl-diamantane parameter and the corresponding vitrinite reflectance value has been established based on their experimental data of the source rocks in Jiyang Depression. This empirical relationship has been used to evaluate the maturity of the condensate in Jiyang Depression. The maturity of the condensate in this area is believed to be highly mature (Ro>1.3%). Meanwhile, by means of the dimenthyl-diamantane parameter, the condensate in Jiyang Depression can be divided into two types, which were from the humic kerogen in coal deposit and the mixed-type kerogen in lacustrine facies, respectively.
