Abstract
Currently, the development of oil and gas fields is often carried out in geological conditions with increased complexity. To increase oil recovery and intensify the flow of oil from oil and gas fields, hydraulic fracturing is most often used. At the same time, in order to obtain the good oil inflow and prevent increased water cut, it is necessary to create a fracture of the required parameters during hydraulic fracturing.
This paper presents the results of hydraulic fracturing modeling using a computer program developed by the authors. In the course of the work, modeling of the dimensions of the fracture was performed for the Vyngapurovskoye field and subsequent verification of the stability of this fracture under the conditions of the rock under consideration using the Griffith theory of strength, as well as modeling the oil inflow from this fracture and calculating the flow rate after the hydraulic fracturing operation.
In result of the studies, it was found that the developed program allows you to evaluate the stability of fractures in the reservoir. In this case, the convergence of the obtained results with the literature data is 98,65%. This confirms the correctness of the developed program and indicates the possibility of using the developed program in practical activities by oil and gas companies.
