东营市地热资源丰富，近年地热资源开采量增加非常迅速。主要开采层位为东营组热储和馆陶组热储，其开发利用方向主要以供暖、洗浴为主。由于综合利用技术不完善，在带来经济效益的同时，不合理开采及尾水的任意排放对当地环境造成一定的负面影响。该文根据当前地热资源开发利用现状及存在的问题，利用梯级开发模式，改善了尾水排放对当地环境的影响，并对东营市地热资源保护与环境治理提出了建议。%Geothermal resource is very rich in Dongying city. Exploitation of geothermal resources has in- creased very rapidly in recent years. Main exploitation layers of thermal energy storage are Dongying for- mation and Guantao formation. Its development and utilization are heating bath. Due to imperfect technol- ogies of comprehensive utilization, the irrational exploitation and the tail water of any emissions have caused some negative impacts to local environment. In this paper, based on the current development of ge- othermal resources and present condition of development and utilization, by using cascade development model, the impact of tail water discharge to local environment has been improved. Some suggestions for geothermal resources protection and environmental governance have been put forward as well.
