A RESONANCE METHOD OF RADIAL OSCILLATIONS FOR MEASURING PERMEABILITY OF ROCK FORMATIONS |
摘要 |
A method for determining permeability of a porous medium of a formation, the method including: placing a logging instrument into a borehole that traverses the porous medium, the borehole filled with a borehole fluid; measuring a pressure, p(1), of an acoustic wave in the borehole at about a boundary between the porous medium and the borehole, the acoustic wave comprising a frequency that is about a resonant frequency of a system that includes the borehole and the porous medium; calculating the permeability from the pressure; and providing the permeability as output to a user. |
