摘要
雄安地区具有优越的地热条件,特别以牛驼镇凸起为代表,具有成熟的地热开发条件。为了更深入探明牛驼镇地热田地热水资源,利用地球物理和地质方法,对该地热田的成因及成藏过程进行分析。结果表明,该区构造演化总体经过以下阶段:古新世-早始新世强烈断陷阶段、早中始新世持续断陷阶段、晚始新世-渐新世断陷晚期、新近纪-第四纪稳定沉积期。牛驼镇地区在元古代-二叠纪时期,受多种构造运动的影响,沉积生成了良好的基岩热储层,并以新近系和第四系地层作为盖层。
Xiong’an area has superior geothermal conditions,especially in Niutuozhen uplift,which has mature geothermal development conditions.In order to further explore the geothermal water resources in Niutuozhen geothermal field,the genesis and reservoir forming process were analyzed by using geophysical and geological methods.The results show that its tectonic evolution generally falls into the following stages:Paleocene-early Eocene strong fault depression stage,early-middle Eocene continuous fault depression stage,late Eocene-Oligocene fault depression stage,and Neogene-Quaternary stable sedimentation stage.During the Proterozoic-Permian period,affected by various tectonic movements,the sedimentation in Niutuozhen area has generated good bedrock thermal reservoirs,with Neogene and Quaternary strata as caprocks.
