摘要/Abstract

摘要：

依据北京孙河断裂区的重力、电阻率测深及可控源音频大地电磁测深(CSAMT)等勘查资料的推断解释，结合多眼地热井钻探揭露的地热地质成果，认为孙河断裂是一条宽3 km左右的断裂带。地热地质构造剖面揭示孙河断裂具有多期活动性，晚侏罗世以来至少发生过两期先逆后张性质的构造活动。剖析了孙河断裂对后沙峪地热田侏罗系火山岩构造裂隙热储地热地质条件的控制作用，进一步分析了孙河断裂带区域的地热地质条件，认为后沙峪地热田西南部是构造凸起型储热构造，北西向延伸的孙河断裂带区域是后沙峪地热田的地热资源富集区。

Abstract:

This paper presents that Sunhe fault in Beijing plain is a buried active normal fault zone about 3 km wide based on the analysis of gravity,resistivity and CSAMT(controlled source audio-frequency magnetotelluric) data and some exploration data of geothermal wells.Geothermal and geological structure profiles reveal that Sunhe fault is of multi-phase activities and has twice tectonic activities at least since Late Jurassic. This paper also analyzes the control effect of fractures in Sunhe fault zone on the geothermal and geological condition of the Jurassic volcanic rocks;it points out that the southwest of the Houshayu geothermal field is located at a tectonic uplift,and Sunhe fault zone is the geothermal source of the geothermal field.

Key words: Sunhe fault, Jurassic volcanic rock, structural crack, geothermal reservoir, geothermal geology
