Hydrogeochemical characteristics of the inter uve of the Kura and Iori rivers in the Republic of Azerbaijan
Separate water-bearing complexes (Chockrak, Maikop, Sarmatian, Eocene, Paleogene, Cre- taceous and others) were investigated. According to the chemical composition, the received waters are hydrocarbonaceous-natrium, chloride-natrium-calcium and sulphate-natrium- calcium. e salinity of subsurface water is up to 42 g/l, the content of boron – from 200 to 2000 mg/l, bromine – up to 64 mg/l. e reservoir pressure is from 170 to 250 atmospheres. e temperature on the depth of 2836 m is 79°C. As for the gas composition, the subsur- face water of the Kura and Iori inter uve is basically methane-containing. A er sampling of separate hydro-geological objects, an in ux of subsurface water to the wellhead with the temperature nearly 49°C was received, and the average discharge of owing wells was about 200 m3/day. Basing on the results of the conducted works, the main parameters of each water-bearing complex (water conductivity, piezoconductivity, etc.) were calculated.
