采用水化学方法对青岛北部地区地热资源远景的探讨

Study on Thermal Resource Future in North Part of Qingdao City by Using Hydrochemical Method

摘要:

采用水文地球化学方法,根据青岛地区50多个地下水样品的测试分析结果进行了地下热储温度的推测,结合遥感解译、测温、地质背景条件等资料综合分析,圈定出3个地热远景区,即温泉地热远景区、黄家山地热远景区和流亭地热远景区,这3个地热远景区均分布在NNE向断裂与NW向断裂交汇部位上。通过对该区地热地质特征初步分析认为,其热储概念模型属深循环对流型。

Abstract:

Using geohydrochemical method, and according to determ ination and analysis results of more than 50 underground water samples in Qingda o area, underground heat reserve temperature is inferred. Combining with remote sense interpretation, thermometry and geological background condition to analyse complicately, 3 geothermal future areas are circled as hot spring geothermal fu ture area, Huangjiashan geothermal future area and Liuting geothermal future are a. These three geothermal future areas all distribute in contacting section of N NE fault and NW fault. Through primary analysis of geological characteristics of geotherm in Qingdao area, it is regarded that heat reserve model belongs to dee p-circulation convective type.
