Abstract:
The main purpose of this work is to model and study the physical processes that occur during acid exposure to the bottomhole zone of a well, taking into account the presence of fractures and the characteristics of well completion. To achieve this goal, a set of new computational algorithms has been created that allow modeling the process of chemical exposure to a productive reservoir using acid compositions. The simulation of the acidic effect process was carried out using special computational methods that allow us to jointly solve the system of well-formation equations. The application of this approach on a number of synthetic and real-world tests is described. The influence of key effects occurring in fractured-pore reservoirs on the effectiveness of acid exposure is demonstrated.
