Three-dimensional Inversion of Gravity Data from Global Geothermal Exploration in Tianshan Sea World in Yinchuan Basin
As a kind of clean energy,geothermal energy has been paid more and more attention by scholars and government departments.Geothermal energy is mostly concentrated in the tectonic plate margin,and China has a unique"ladder"topography,more areas in the plate collision boundary,geothermal resources are rich,but there are problems of low exploration and utilization.Yinchuan Basin contains abundant geothermal resources and is a conductive geothermal area of sedimentary basin,which has great potential for geothermal resources development.Gravity anomaly mainly reflects the density difference of underground rocks,and gravity exploration method is widely used in geothermal exploration,especially in the division of prospective geothermal areas,because of its low cost and wide exploration area.The three-dimensional gravity inversion method was used to invert the world gravity data of Tianshan Sea World in Yinchuan Basin,and the regional three-dimensional density structure was obtained,providing a basis for the exploration and utilization of geothermal resources in this area.
