FIELD: oil and gas extractive industry.
SUBSTANCE: method includes saturating of probe with analog of bed water, measuring of natural potential for diffusion origin Ed and electrochemical potential Eda, determining diffusion-absorption activity Ada on basis of mathematical expression and use of value of diffusion-absorption activity Ada for numeric estimation of hydrophoby of porous space. In case of full hydrophoby of porous space Eda=Ed, and Ada=0.
EFFECT: higher precision of evaluation of wettability of porous space surface.
