Abstract:
Based on all oil gas chromatography/mass spectrometry quantitative analysis, characteristics of heterogeneity of bicyclic sesquiterpenes and its variation rules in spatial distribution were analyzed, geological geochemical significance of the characteristics was discussed. The results showed that microbial degradation had no significant effect on bicyclic sesquiterpenes, which were abundant in crude oil produced from Wen'an Oilfield; the distribution of bicyclic sesquiterpenes was that the relative abundance of C14 sesquiterpenoids was least, C15 sesquiterpenoids was middle, and C16 sesquiterpenoids was most; there was significant heterogeneity between south and north blocks of Wen'an Oilfield; there was a significant correlation among the ratios of relative abundance between rearranged drimane and 8β(H)-drimane, C30 rearranged hopane and C30 hopane, and C27 rearranged sterane and C27 sterane; formation mechanism of rearranged drimane was similar with that of rearranged hopane and rearranged sterane; heterogeneity of molecular composition of crude oil indicated that there were two different genetic types and two oil and gas accumulation systems possibly in the south and north blocks of Wen'an Oilfield.
