Abstract

For a crude oil sample from Ordovician reservoir in Well Caogu100 Ping 19 in Jiyang depression, Shengli Oilfield, North China, hydrocarbons except for tricyclic terpane, hopane and 25 norhopane homologues were completely depleted in saturated fraction, as well as hydrocarbons except for triaromatic steranes in the aromatic fraction, which indicate that severe biodegradation occurred in this reservoir. Completely depleted n alkanes unaltered by water washing and dibenzothiphenes resistant biodegradation in the oil sample implied apparently that the alteration occurred in this reservoir was associated with biodegradation together with water washing. The magnitude of "UCM" hump existed in the aromatic fraction is apparently larger than that of "UCM" hump existed in the saturated fraction, which implied that the biodegradation rate for aromatic hydrocarbons is parallel or even exceed that of the saturated hydrocarbons. The fast biodegradation of aromatic hydrocarbons with lower molecular weight, as well as the occurrence of abundant 25 norhopanes, indicates that the alteration occurred in the aerobic environment other than in the anaerobic condition.
- Jiyang depression,
- biodegraded crude oil,
- 25-norhopane,
- aerobic biodegradation,
- water washing
