Problems of exploration and development modeling of oil fields

Abstract

The article shows the construction features of geological and geological-hydrodynamic models for solving various problems: prospecting, exploration, development and design of enhanced oil recovery (EOR) methods application. Depending on the tasks assigned, the simplest models should gradually and continuously become more complex. When constructing geological models, it is necessary to take into account all the geological reserves in the subsoil of the object under consideration, regardless of whether they can be extracted today or not. In this case, much attention should be paid to the so-called tight (in the modern sense) sections between the layers and the study of their role in filtration processes. In the construction of geological and filtration models for deposits with hard-to-recover oil reserves, it is necessary to study the details of the geological structure and especially the fracturing, since these details have a determining effect on the efficiency of the development and application of the EOR. Essentially new approaches to modeling are presented.
