Abstract:

The new concept of pore throat-cavity junction and the rock pore throat-cavity junction model have been presented in this paper. A law of rock pore throat-cavity junction is obtained by means of computer modeling and mercury-injecting, and the pore throat-cavity theory is developed It is reported in this paper that the application of this theory to rock conductivity, permeability, mercuryinjection, residual oil saturation, reservoir recovery and so on is successful.
