| Summary: |
The influence of water to cement ratio and degree
of hydration to the dispersion characteristic of oilwell cement
slurries during 24 hrs of hydration is evaluated and expressed
in the form of magnitude and frequency effect at above cutoff
frequency. It is observed that the magnitude of conductivity
dispersion increases with the reduction in water content and
pore volume. At initial hydration, the dispersion characteristic
appears in the minimum value and raises as hydration
continue. The frequency effect is growth as the hydration and
saline concentration increases. It is shown that the single
frequency measurement for evaluating the cement slurries
properties may not be reliable. An implicit correlation to the
interface conductivity is indicated from dispersion respond
throughout hydration process. |
