Abstract: On the basis of analyzing the available formula of permeability, the feasibility and method of establishing a general model of permeability prediction have been investigated by using mathematical tools. The results show that the proposed model,which employs the 2-D trend surface analysis, not only deals
with the problem better, but also yields higher precision in permeability prediction.

Key words: sand-shale formation, permeability prediction, mathematical model, trend surface analysis
