Abstract
In the present study, the effect of fluid motion on plastic and elastic plastic deformations in subsurface fluid reservoirs has been investigated, focusing on oil reservoirs. This type of modeling and investigation of plastic deformations and strains has always been one of the most important issues in the management and development of the oil industry and oil reservoirs. Fluid flow in oil reservoirs and in porous media is studied at various scales. This creates numerous challenges in reservoir simulation in terms of accuracy, precision, and computational power. In this regard, the multi-scale, multi-physics hybrid model has recently been introduced as an efficient model in this simulation. In this paper, the process of upgrading the above model for accurate modeling of the solid phase and also the interaction of this phase with the fluid phase is presented. To upgrade the mentioned model to a geomechanical model with plastic simulation capability, an integrated behavioral model was used to model the behavior of reservoirs, which has an integrated yield function and uses an implicit method for solving equations simultaneously and for convergence. The simulation results have shown that the elastic-plastic behavior model, combined with the aforementioned model, provides a powerful model for simulating oil reservoirs with high-amplitude deformations.
