德州市城区地热水动态与开采量关系

Study on Relationship between Movement and Extraction of Geothermal Water in Dezhou City

摘要:

德州市城区多年来因地热水大量开采，地热水位持续下降，并形成了以德州市城区为中心的地热水降落漏斗。根据区内馆陶组热储多年地热水动态与开采量进行分析研究，查明了区内地热水动态与开采量的相互关系，进一步揭示了人为活动的影响，建立了区内地热水动态与开采量相关方程，并通过方程曲线态势分析，提出了区内地热集中开采区馆陶组热储地热水预警开采量，为区内地热资源的可持续开发利用提供了科学依据。

Abstract:

Due to massive exploitation of geothermal water in Dezhou city in many years, geothermal water level continued to decline, and formed a geothermal water depression cone centered in Dezhou City. Based on the analysis of water dynamics and geothermal exploitation rate in Guantao geothermal reservoir, the relationship between the amount of geothermal water withdrawed and water dynamics has been verified, and the impact of human activities have been furtherly revealed, and the correlation equation between the amount of geothermal water withdrawed and water dynamics has been set up. Through analysis on the equation trend, a warning exploitation rate of geothermal water in Guantao reservoir is put forward. It will provide a rational and scientific basis for the sustainable development and utilization of geothermal resource
