Methodological bases of complex geomechanical studies for selecting optimal parameters of drainage of waterlogged areas fields

Abstract

This article provides examples of an integrated approach to the study of the geomechanical features of mineral deposits responsible for the filtration properties of a massif and, as a result, increased water cut of the field as a whole. Having knowledge of a number of characteristics that affect the water conductivity of the massif, it seems possible to select the parameters of the drainage system of the field in such a way as to minimize the cost of creating an intake due to the point arrangement of water-reducing wells. Structural-tectonic disturbances with geodynamic mobility, due to which aquifers and caverns in karst rocks remain open and are not filled with clay and sand materials, are the main search features of aquifers. The boundaries of the zones of structural-tectonic disturbances and their spread are well detected by ground-based geophysical methods, such as electrical exploration (boundaries of disturbances) and spectral seismic profiling (depth of propagation of zones of increased fracturing). It is proposed to use satellite geodesy as the most effective way to determine coordinates at large bases as geodetic methods for studying modern geodynamic activity. The examples of dewatering the fields using the proposed approach have shown their high efficiency at minimal cost for the creation of water intake facilities. This technique allows you to get the greatest effect under the conditions of aquifers confined to the rocky mountain range, especially in conditions of karst propagation.
