| Abstract: | In order to study the regularity of microscopic sealing property of cap rocks rnacroscopically, a relationship between the displacement pressure of cap rocks and the acoustic interval transit time has been suggested in this paper. Based on large amount of experimental data, the variation of displacement pressure in a district east of Daqing placanticline of cap rock are studied both laberally and vertically with this method. |
