Geodynamic prerequisites and reflection of signs of fluid migration in hydrogeochemical indicators of formation water in the Bukhara-Khiva region

Abstract

The article describes the results of a study of changes in the composition and hydrogeochemical parameters of individual areas and fields of the Bukhara-Khiva region based on well materials. Vertical zonality of hydrogeochemical parameters associated with deep fluid flow and heat and mass transfer is noted. The manifestation of tectonodynamic conditions in the Mesozoic-Cenozoic history of the region, which served as a prerequisite for the formation of weakened zones (channels of deep heat and mass transfer) in the field of tensile stresses for the vertical migration of fluids and juvenile gases, is noted. A hydrogeological criterion for identifying zones of deep heat and mass transfer and vertical fluid migration is proposed. Keywords: wells; oil and gas; formation waters; fluids; hydrogeochemical indicators of formation waters; heat and mass transfer.
