Modeling of Filtration Investigations Under Unstable Conditions of Injection of Water Into Hyperlow-Permeability Samples

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

We report the results of modeling laboratory experiments for unstable filtration conditions. It has been shown that the form of pressure curves is influenced by the spurious volume coefficient, the length of the core sample, and the collectorpermeability. We have diagnosed by the log-log curves of the pressure and its logarithmic derivative the liquid flow conditions for early and later times of the nonstationary filtration experiment influencing the possibility of estimating the collector permeability.
