为了评价贵德盆地深部地热资源远景,使用V8仪器进行了地面大地电磁法和可控源音频大地电磁法工作,首次对贵德盆地深部电性特征和深部地热资源进行评价.查明贵德盆地基底埋深3600 m～4900 m.推断盆地第三系上新统贵德组(上部地层)是浅部热储层,其厚度为370 m;其埋深为530 m.老第三纪渐新统(上部地层)是中部热储层,其厚度为640 m～800 m,其埋深为1810 m～2330 m.侏罗纪、白垩纪地层是深部热储层,其厚度为970 m～1600m;其埋深为3680 m～4990 m.提出浅部热储层属于盆地型层状热储;中深部热储层属于断裂型带状热储.推断出二条大断裂破碎带.

In order to investigate the deep geothermal resource in Guide basin,MT and CSAMT surrey are carried out by using V8 instrument.Deep geo-electric structure and and deep geothermal resources have been investigated for the first time.It has been verified that the depth of the basin bed is about 3600 m～4900 m.The depth of shallow geothermal resources of Tertiary Pliocene Guide formation group is 530m,the thickness of it is 370m,the depth of middle geothermal resources of late Tertiary Pliocene Guide formation group is 1810 m～2330 m,the thickness of it is 640m～800 m,the layer of Jurassic and Cretaceous group is a deep geothermal resource layer.the buried depth of it is 3680 m～4990 m,the thickness of it is 970 m～1600 m.The conclusion is that the shallow geothermal resources belong to basin layer-type;the middle and deep Geothermal resources belong to the fault type.Two faults have been inferred and defined.
