禹城市城区东营组热储地热资源赋存特征研究

摘要

山东省禹城市城区在大地构造上属于华北陆块、华北拗陷区、济阳坳陷区、惠民潜断陷、临邑凹陷南部。通过已有钻探资料及近年的勘查项目研究成果，对禹城市城区东营组热储的地热资源的地质背景、水文地质特征、地热流体化学特征等进行了综合研究分析，认为禹城市城区东营组热储属于层控型低温地热田，地下热水矿化度较大，成因主要为大气降水。%District areas of Yucheng city in Shandong province belongs to north China landmass,north Chi-na depression area,Jiyang depression area,Huimin hidden fault depression and Linyi depression in tecton-ics.Through drilling data in recent years and exploration projects and research results,geological back-ground,hydrological geological characteristics,geothermal fluid chemical characteristics of geothermal re-sources in Dongying formation in district areas of Yucheng city have been studied and analyzed comprehen-sively.It is regarded that geothermal reservoir of Dongying formation belongs to strata bound type low temperature geothermal field.Salinity of underground hot water is large,and is fomed by precipitation.
