【摘要】 以往根据大地地温平均梯度划分,邯郸地区一直被作为非地热异常区而没有被重视,致使地热研究程度低。本文以邯郸汽贸城区的地热资源勘查为例,主要利用重力与可控源音频大地电磁法的综合应用,说明此综合物探技术在实现对地热存储条件和热储空间分布的勘查与有利地热井区预测的综合效果。该方法充分利用重力法对基底构造平面异常的显示优势和电磁法对剖面构造异常的刻画优势,从而形成对地热异常体的三维显示与定位。最后,讨论了综合地球物理勘查技术在今后地热勘查新突破中的应用前景。本文研究内容为邯郸地区进一步开展深部地热开发提供了依据,也对丰富地热勘查理论具有一定的实际意义。更多还原

【Abstract】 According to the average geothermal gradient,Handan area has not been used as an geothermal anomaly area and has not been paid much more attention to and has the low degree of the geothermal research.In this paper,geothermal resources exploration in the Handan car trade city is viewed as an example to mainly explain the comprehensive application and effect of gravity and controlled source audio-frequency magnetotelluric sounding method which realized exploration in the geothermal storage conditions and distribution of thermal storage space and predict the favorable geothermal well block.The method makes full use of the advantages of gravity in basement structure and plane abnormal and the advantages of electromagnetic methods in profile structural abnormal so as to form 3D display and localization of geothermal abnormal body.Finally,the application prospect of integrated geophysical exploration technique is discussed in the new breakthrough for geothermal exploration.The research content of this paper provides a basis for the Handan area to further carry out deep geothermal development,and has certain practical significance for rich geothermal exploration theory.更多还原
