| Abstract |
Dagestan is one of the pioneers in matter of analysis and industrial development of geothermal resources in Russia. Despite lacking obvious volcanism, mountain-filled Dagestan is rather rich in thermomineral sources and geothermal anomalies (Ahti, Hnov, Richalsy, Giljar, Berikey, Duzlak, Alchadjikent, Kayjakent, Adgi, Istisy, Miatli, Hzanor etc.). In premountain-flat Dagestan by drilling in gas-oil reservoirs and the thermal waters are reconnoitered with forecast estimation of resources of a field of low mineralized (3-15 g/l) thermal waters with temperature 50-105??: Makhachkala, Izberbach, Kayjakent, Kizlar, Tarumovka, Jurkovka, Kargalinskoe, B.Areshevka, Rechninskoe, Kardonovka, Terekli-Mekteb and Chervlenie Buruni. Since 1963, the thermal waters have been utilized widely with considerable economical and ecological effect for a central heating, ardent water facilities, sanatorium-balnealogical purposes and bottling of medical-restaurants mineral waters ("Deneb", "Richalsy", "Makhachkala-160", "Sarmatskaya", "Kardonovka" etc.). Designs and methods of boring and exploitation of geothermal wells, including acclinal and horizontal drilling will fractionally be realised in production. The original minings on transforming a geothermal energy in calorific both electric and heat supply systems on the basis of geothermal circulating systems, original plutonic heat exchangers and with usage of heat pumps for low- and mean potential hydrothermal resources are executed. |
