Research on 3D geological modeling of medium-deep geothermal based on geophysical methods:Taking Kaifeng City as an example
It is more convenient and time-saving to use geophysical prospecting method for 3D geological modeling of medium-deep geo-thermal formation than traditional geological borehole data modeling.Using ultra-low frequency methods to conduct geophysical prospec-ting surveys in Kaifeng City and comparing geophysical interpretation results with geothermal well logging curves,on the basis of geo-physical prospecting interpretation,a three-dimensional geothermal geological model of Kaifeng City was established by FEFLOW soft,and the model was verified by water flow field,geothermal field and hydrogeological parameters.The results show that the geophysical prospecting interpretation results are reliable and the parameters of the model are basically consistent with the actual geological condi-tions,geophysical method is feasible in 3D geological modeling of geothermal field.
