| Pressure Penetration Test | испытание статического воздействия различных растворов под давлением на проницаемость моделей горных пород (Shale Permeability using the Pressure Penetration Test (PPT). Pressure penetration technique (PPT) tests have been performed to investigate the effect of physical plugging by nanoparticles. Using this technique, we measure the permeability of shale samples in contact with various kinds of fluids: brine, base mud, and base mud with various concentrations of nanoparticles. ixtra) |
