禹城市城区东营组热储地热资源赋存特征研究

Study on Occurrence Characteristics of Geothermal Resources in Dongying Formation in District Areas of Yucheng City

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。

Abstract:

District areas of Yucheng city in Shandong province belongs to north China landmass, north China depression area, Jiyang depression area, Huimin hidden fault depression and Linyi depression in tectonics. Through drilling data in recent years and exploration projects and research results, geological background, hydrological geological characteristics, geothermal fluid chemical characteristics of geothermal resources in Dongying formation in district areas of Yucheng city have been studied and analyzed comprehensively. 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.
