摘要
Abstract
Taking the Yibin section of the Jinsha River as an example,this paper studied its geothermal resources and potential from geological background,hydrogeology,tectonics and heat-storage conditions.It is indicated that the paleo-geographic environment is favorable for migration and cycling of underground thermal water as well as exchanging heat with the deep heat-storage reservoir.This helps to form relatively closed thermal structures,making the deep thermal water be in pressurized situation.The cap rocks can increase thermal insulation and control thermal diffusion,and prevent the surface water from migrating downward.And this region is located at the junction of several faults which provide conduits for the thermal water convection at depth.The water precipitated downwards from higher places in this area,passing over a long distance and to a big depth.Extensive thermal exchange with hot wall-rocks occurred when the water was resorted at depth for a long time.The geothermal resources in this area have a big economic potential.关键词
