A Pressure Transient Model for Power-Law Fluids in Porous Media Embedded with a Tree-Shaped Fractal Network

Abstract EN

This work studies the pressure transient of power-law fluids in porous media embedded with a tree-shaped fractal network.

A pressure transient model was created based on the fractal properties of tree-shaped capillaries, generalized Darcy’s law and constitutive equation for power-law fluids.

The dimensionless pressure model was developed using the Laplace transform and Stehfest numerical inversion method.

According to the model’s solution, the bi-logarithmic type curves of power-law fluids in porous media embedded with a tree-shaped fractal network are illustrated.

The influences of different fractal factors and Power-law fluids parameters on pressure transient responses are discussed.
