东营市城区地热储人工回灌条件及分区研究

Study on Condition of Artificial Recharge & Partitions of Geothe rmal Reservoir in the Urban Area of Dongying City

地热水资源开发利用往往伴生诸多环境地质问题,人工回灌是解决这些问题的有效和重要手段[1]。影响人工回灌效果的主要因素有地质构造复杂程度、回灌水源类型,热储厚度、渗透性能、储水能力,地热水头大小及溶气状况等。就东营市城区馆陶组、东营组地热水资源的人工回灌条件进行了论述,并利用综合方法开展了分区评价,划分出回灌条件好区、较好区、一般区和较差区。对该区地热水资源人工回灌的可行性进行了讨论,提出了建议。

There are many environmental geological problems in the development and utilization of geothermal water resources. The artificial recharge is the effective and important way of solving these problems. There are several main factors which could affect the result of artificial recharge, such as geological structural complexity, recharge water types, thickness of thermal storage, permeability, ability of water storage, head size of geothermal, status of water solution and so on. The paper is based on discussion that the condition of artificial recharge of Guantao formation and Dongying formation in the urban area of Dongying city, and carries out partition evaluation by synthesis methods, and divided into the best, better, normal and worse partitions. Finally,it puts forward some advices.
