Abstract
Study on the characteristics of capillary pressure curves of direct argillaceous cap rocks for natural gas from paleozoic in shanganning Basin was carried out in this paper. The parameters,which have been obtained in the process of experiment, show that the direct argillaceous cap rock has above medium power to seal natural gas. Those parameters are the pore throat median diameter, median pressure, change coefficient of the frequency distribution of pore throat and the pemeability contribution. The results also show that the pore throat median diameter is proportional to the maximum mercury saturation, but disproportional to the median pressure and the change coefficient.
