Abstract
The article presents the results of updating the geological and hydrodynamic model of the V5 formation.
The aim of the work was to improve the forecast of filtration and reservoir properties and development indicators using a geological and hydrodynamic models.
Materials and methods. Reference wells with core and well logging were used as initial data. According to core data, a correlation between absolute permeability and the granulometric composition of rocks was revealed. The double growth parameter of gamma ray logging was used as a parameter responsible for granulometry. The model of the porosity-permeability relationship is adopted according to the concept of pore space connectedness.
Results. The refined dependence of permeability calculation was successfully applied in geological and hydrodynamic modeling. Based on the results of well adaptation, a decrease in the dispersion of permeability multipliers is observed.
Conclusion. The obtained results confirm a significant improvement in the prediction of the hydrodynamic model when using this approach.
