Аннотация
We develop and study a 3D elasto-plastic model for core recovery based on algorithms of simulating the process of creating a well and separating the core. Estimates of the rock deformation processes are presented for different cases: taking into account localization zones of deformation, the effect of the drill tool, the presence of very plastic interlayers, a non-equiaxial initial stress state in the reservoir. Our model can be used for evaluation of safe core recovery in different natural reservoirs.
