Аннотация:Numerical modelling of flows in geologic porous media with account for plastic behavior of rocks at high temperatures and hydrofracturing at high fluid pressures is required for better understanding of hydrothermal and volcanic systems. Investigation of these systems is limited due to lack of reliable and being at hand reservoir simulation software that accounts for the complicated rock behavior at elevated temperatures. In this paper we present such software as an extension of the MUFITS reservoir simulator. We describe the mathematical model utilized for modelling of elastic and plastic behavior of rocks and input data formats to the simulator. We present several application examples related to modelling of the brittle-ductile transition in hydrothermal systems, in particular perturbed with emplaced degassing magma body, and provide the corresponding simulator input data to facilitate and ease its further usage.
