چکیده انگلیسی
Conventional geochemical diagnostic parameters in the saturated hydrocarbon fraction are affected by biodegradation. Based on the intensity of n-alkanes, hopanes and 25-NHs, many samples from Caoqiao appear to have experienced both biodegradation and continuous charge. A wide range of geochemical parameter values from different components point to multiple oil charge mixing. The relationship between the absolute concentrations of n-alkanes to hopanes and hopanes to 25-NHs of the samples can qualitatively differentiate whether oil charge mixing occurs in reservoirs or not. The cross plot of n-alkanes and hopanes dynamically describes the processes of continuous charge mixing and biodegradation. The positive correlation between the concentrations of hopanes and 25-NHs may suggest that oil charge mixing and biodegradation proceed continuously, while the negative correlation may indicate charge stops due to some geological factors.
