摘要
Based on steady filling,the physical property and attitude of carrier layer have been changed so as to analyze their influence on hydrocarbon migration pathway in carrier layer junction.The physical property limit for predominant pathway change in carrier layer junction has been calculated at different angle through theoretic study and experiment.If physical property equals to the critical value,both the two transport layers can work as favorable migration pathway.A quantitative model has been established so as to predict favorable pathway in carrier layer junction.
