Low-frequency experimental investigation of the frequency and temperature dependences of the electrical conductivity of asphalt-resin-paraffin deposits in reservoirs
Annotation
We performed experimental studies of the phase-frequency and the amplitude-frequency characteristics of the electrical conductivity of asphalt-resin-paraffin deposits in oil storage reservoirs within the frequency range of 4 Hz–1 kHz and the temperature range of 20–70∘C. We found two domains in the obtained temperature dependencies. For the temperature range below the phase-transition temperature, the activation energy was equal, on average, to 0.52 eV, while above this it was approximately 1.00 eV. The peculiarity of the frequency dependences of the phase–frequency characteristics results from the multi-factor mechanisms of the polarization, which resulted in “smearing” of their extremes over these frequencies.
