Abstract
This work purpose was to develop a method for determination of the effective viscosity of the granulated gel PPG for blocking anthropogenic fractures (auto-FHF fractures) which is applied at later stages of oil fields development. Using the laboratory fracture model the values of constants (apparent constant consistency and the apparent index of pseudoplasticity) for the equation of viscoelastic liquid were obtained. The same constants were used to derive the equation for pressure gradient along the anthropogenic fracture. The gel viscosity is calculated by the equation of gel movement along the fracture. This equation enables to predict the gel viscosity for each size of granulated gel fractions depending on the fracture width and the gel injection velocity.
