摘要
利用物探方法进行中深层地热三维地质建模,比传统地质钻孔资料建模更方便和省时.采用超低频探测方法在开封市开展物探探测,并将物探解译结果与地热井测井曲线进行对比,在物探解译基础上,采用FEFLOW软件建立开封市三维地热地质模型,对模型进行水流场、地温场和水文地质参数赋值验证.研究结果表明,解译数据可靠,模型各项参数与实际地质条件基本相符,说明物探方法在地热三维地质建模中具有较好的可行性.
Abstract
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.
