利津县城区地热资源状况及开发前景分析

Analysis on Geothermal Resources and Its Development Prospects in Districts in Lijin County

摘要:

利津县城区的地热资源主要赋存于新生代新近纪和古近纪碎屑沉积岩中，热储类型为层状孔隙-裂隙型热储，地热资源类型属热传导型。新近纪馆陶组热储层组与古近纪东营组热储层组是主要的热储层。该文在论述利津县地热地质条件的基础上，对地热开发的经济、社会、环境效益及开发利用前景进行了分析，对地热开发中的尾水排放和回灌问题进行了探讨，最后提出了地热资源开发与管理方面的建议。

Abstract:

Geothermal resources in districts in Lijin county are mainly hosted in Mesozoic and Cenozoic Neogene and Paleogene sedimentary rocks. Its geothermal reservoir is layered pore-fractured type, and geothermal resource type is heat conduction. Thermal reservoirs in Neogene Guantao formation and Paleogene Dongying formation are major geothermal reservoirs. In this paper, on the basis of discussing geological conditions of geothermal resources in Lijin county, the economic, social and environmental benefits and exploitation prospects of geothermal resources are analyzed, problems occurred in tail water discharge and recharge during the period of geothermal exploration are discussed, and suggestions for development and management of geothermal resources are put forward as well.
