Medium-low Temperature Geothermal Reservoir and Its Thermal Field in Drilling Well
Abstract:The utilization of medium-low temperature hot water has broad and bright prospects.The study of its formation and accumulative regularity is the basis of the rational exploration and exploitation of medium-low temperature hot water. According to geothermal theory, stratigraphic features and structural and hydrogeological conditions, this paper has discussed the conditions for the formation of heat conduction type geothermal reservoirs and suggested a classification of geothermal reservoirs. Furthermore, the thermal field in drilling well and the drilling fluid temperature are analyzed, the distribution of drilling fluid temperature and the relationship between temperature variation and strata are pointed out. The conclusion of this paper is useful to the exploration and utilization of geothermal energy.
