Development of the rocks fracturing model on the Carpathian region example

摘要

The proposed model will allow evaluating the fracturing of the sandy seams, taking into account geodynamic processes. The model is based on the fact that the main factor in the formation of the original fracturing is stress-deformation state of the rocks during the period of active geodynamic processes. The mechanical properties of the Carpathian rocks are processed for such estimation. Samples of rocks were selected according to stratigraphy, lithology and depth. Sediments of Cretaceous system, Paleogene and Neogene take part in a geological structure of the territory. Age of rocks, lithology and depth are taken into account when sampling for further research, because these parameters can change the mechanical properties of rocks. The 2D finite element model is developed, that model will demonstrate the dependence of fracture strength on the geometric characteristics of a sandstone seam within the anticline. The results of these studies will make it possible to be tter predict the high permeability zones for the epigenetic reservoirs formation. This will allow conducting the secondary explorations of the oil and gas fields.
