郑州东部新城区地热资源综合物探解释研究

为了更好地了解地下地质情况，克服单一物探方法解释的局限性，此次地热资源勘查过程中采用了重力测量、广域电磁测深、大地电磁测深与地震测量4种物探方法，以便提高物探成果的可靠性和解释精度，进而达到解释成果的准确性。根据重力测量、广域电磁测深反演、大地电磁测深反演和地震反演处理结果，基本查明了勘查区地层发育状况以及断裂结构特征和热储层埋藏条件、分布特征等。通过对多种物探方法的联合综合地质解译，获得勘查区断裂、地层的热储层空间展布特征。研究为圈定地热富水有利区提供了技术支持。

Study on comprehensive geophysical interpretation of geothermal resources in new urban area of eastern Zhengzhou

In order to better understand the underground geological conditions and overcome the limitations of the interpretation of single geophysical prospecting method，four geophysical prospecting methods，namely gravity survey，wide-area electromagnetic sounding，magnetotelluric sounding and seismic survey，were adopted in the geothermal resource exploration process，in order to improve the reliability and interpretation accuracy of geophysical prospecting results and thus achieve the accuracy of interpretation results.According to the gravity data processing results，wide-area electromagnetic sounding inversion，EH-4 inversion and seismic inversion processing results，the formation development status，fault structure characteristics and thermal reservoir burial conditions and distribution characteristics in the exploration area have been basically identified. Through the joint and comprehensive geological interpretation of various geophysical prospecting methods，the spatial distribution characteristics of thermal reservoirs of faults and strata in the exploration area are obtained. The study provides technical support for the delineation of favorable geothermal water-rich areas.
