This paper is devoted to the modeling of hydraulic fracturing of a layered medium under the action of uneven injection of non-Newtonian fluid. The medium is represented as a set of horizontal layers, each of which is characterized by its own values of minimum compressive stress, elastic moduli, toughness and leakage coefficient. To determine the crack geometry, the front velocity equation is solved, universal asymptotics and the explicit time integration scheme are used. Approbation of the model is carried out by comparison with the published results of other authors.
