滨州市城区地热地质条件与开发利用前景

Geological Condition and Exploration and Utilization Future of Geothermal in Urban Areas of Binzhou City

摘要:

滨州市城区主要热储层为赋存于地下1000~1600m的新近纪馆陶组和古近纪东营组,属碎屑岩孔隙-裂隙类型。热储层为砂岩、砂砾岩,厚度140~250m;水化学类型主要为C l-Na型;井口水温为60~65℃,属温热水型地热资源。热水中富含对人体有益的微量元素;允许可开采量2556×104m3/a,现状开采量109.5×104m3/a,开发利用潜力大,前景广阔。

Abstract:

Major geological reservoirs in urban areas of Binzhou city occur in Neogene Guantao formation and Paleogene Dongying formation under the ground of 1000~1600m.It belongs to fragemental crack type geothermal.Thermal reservoirs are composed of sandstone and conglomerate with the depth of 140~250m.Hydrochemical type is Cl-Na,and the temperature of the mouth of the well is 60~65℃,which belongs to middle temperature type geothermal resource.Many useful elements are included in thermal water.Its permitted exploita...
