原油厌氧微生物降解特征分析
Characteristics of crude oil biodegradation by anaerobic microbial
摘要
Abstract
To study the characteristics of crude oil biodegradation and transform to heavy oil,the oil came from Shengli Oil Field was selected to carried out biodegradation experiments on the Henget anaerobic microorganism operation platform.Results showed that the thin oil could be biodegraded and transformed to heavy oil.The degradation of 248 d per gram of crude oil could produce 3.0 mmol methane,even could be reached 6.4 mmol methane(B76)after supplying mineral nutrition.The isotope-ratio deviation of 13C(δ(13C))of methane coming from Y141 oil distributed from-4.636% to-4.527% and the δ(13C)of CO2distributed from 0.424% to 0.850%,and the δ(13 C)of methane coming from B76 oil distributed from -4.983% to -4.853% and the δ(13 C)of CO2distributed from 0.254% to 0.465%.Saturated hydrocarbon of crude oil was degraded greatly from 72.77% to 44.0%.There were no significant changes in two kinds of crude oil,such as cholesterol,alkane and other biomarkers,which indicated the oil had suffered little biodegradation.The characters of oil and gas in the process were important for exploration and development of heavy oil.关键词
