Considering the complexity of hydrodynamic processes when drilling wells, the problem of using mathematical modeling in the study of these processes becomes relevant. It is currently impossible to build a mathematical model that would cover the entire cycle of work required for drilling wells and developing field due to the influence of many factors. In this regard, researchers usually perform mathematical modeling for individual technological operations, such as cuttings removal processes. The article presents the results of numerical modeling of the flushing fluid supply process using the ANSYS Fluent software package based on fields testing data. The distribution fields of static pressure, flow velocity and dynamic viscosity were obtained. Mathematical modeling using modern software systems, such as ANSYS Fluent, makes it possible to study individual processes. The results of studies of the process of flushing fluid outflow can be used in future to find patterns of interaction of fluid flow with rock, filtration, changes of reservoir properties and fluid penetration, and, ultimately, to model the processes of cleaning the reservoir zone and stimulating the inflow.
