摘要

Objective Faults are the main channel of hydrocarbon vertical migration in a faulted basin(Jiang et al.,2018).It is helpful to guide the exploration by accurately evaluating the opening and sealing characteristics of faults at different depths.However,the fault vertical opening and sealing properties cannot at present be evaluated quantitatively.Taking the Raoyang Sag in the Bohai Bay Basin as an example,based on the stress analysis of the fault zone,this research analyzes the factors influencing the opening and sealing characteristics of fault zones and proposes a quantitative method for evaluating fault vertical opening and sealing properties during hydrocarbon-charging periods.
