与苯并藿烷相比,25-降苯并藿烷的研究较少,目前这类化合物仅检出于加拿大和我国川西北的降解沥青中。本研究在塔河油田井下奥陶系储层稠油中检测到了完整系列的25-降苯并藿烷(C31-C34),发现25-降苯并藿烷与苯并藿烷的比值与现有的生物降解评价参数有较好的可比性,且该参数在不同降解程度原油中的差别比其他参数更大,故今后有必要对其开展更深入的研究,以便更精细地评价原油的生物降解程度。

Compared to extensive investigation of benzohopanes, the occurrences of 25-norbenzohopanes were only reported in biodegraded bitumens of Canada and NW Sichuan Basin. In this study we identified the complete series of 25-norbenzohopane (C31-C34) in severely biodegraded oils from the Ordovician reservoirs in Tahe Oilfield and found that the ratios of 25-norbenzohopane to corresponding benzohopane are well correlated to other parameters reflecting biodegradation extent. In addition the new ratio parameter is more sensitive than others and therefore it is necessary to further evaluate this new parameter in future studies to obtain more detailed information on biodegradation extent.
