SIMULATION OF THE FILTRATION IN A LOW-PERMEABILITY POOL WITH TWO PERPENDICULAR TECHNOGENIC HYDRAULIC FRACTURES

Results of numerical simulation of the filtration of a fluid in a well with two perpendicular technogenic hydraulic fractures in a low-permeability pool are presented. It was assumed that the filtration in the producing pool and in the fractures adheres to the Darcy law and the permeabilities of the fractures exceed the permeability of the pool by approximately 105 times. Because of the small opening of the fractures, as compared to their length and the distance between them and the boundaries of the pool, the flow of the fluid in the fractures was assumed to be one-dimensional. The influence of the flow capacity and geometry of the primary fracture on the change in the pressure in the well with time was analyzed, and the nonstationary pressure fi elds in the well–fractures–pool system were calculated.
