Method and apparatus for determining dielectric permittivity of subsurface formations |
摘要 |
Well logging techniques are set forth for obtaining improved measurements of formation dielectric permittivity, conductivity, and water-filled porosity. The effects of dielectric and conductivity frequency dispersion are considered and utilized. In a disclosed embodiment, a corrected dielectric permittivity of a formation surrounding a borehole is determined using the following steps: deriving a measured value of formation dielectric permittivity from a logging device which traversed the borehole; deriving a measured value of formation conductivity from a logging device which traversed the borehole; determining a formation dielectric permittivity dispersion value as a function of the measured conductivity; and determining a corrected formation dielectric permittivity from the measured value of dielectric permittivity and the dispersion value.
