摘要

青岛蓝色硅谷区域地质构造特殊,地热资源丰富。目前该区域地热资源的勘查程度较低,地热资源利用形式单一,优质地热资源浪费严重。本文采用岩土热响应测试法对蓝色硅谷区域内的地埋管测试孔的岩土热物性进行了现场测试,利用48 h的测试数据,采用线热源模型进行数据分析,得到土壤导热系数为2.278 W/(m∙K)。同时,采用柱热源模型模拟夏季工况,得到的流体温度变化趋势与实验工况相同,且进、出水温度分别为35.1℃和30.4℃,与实验工况下的35.1℃及30.8℃吻合较好。该研究可用于指导土壤源热泵的热物性分析以及青岛蓝色硅谷地热资源综合开发。

Abstract

The Qingdao Blue Silicon Valley region has abundant geothermal resources for its special geological structure. However, due to the low degree of exploration and lacks comprehensive evaluation, the utilizing form of geothermal resources is single, and the high-quality geothermal resources are serious waste. In this paper, geotechnical thermal response test based on lineal heat source model was used for field test to study the geotechnical thermal physical properties of buried test holes in the Blue Silicon Valley region. Result of the 48-hour test data analysis showed that, the calculated thermal conductivity of the soil was 2.278 W/(m∙K), which ensures the heat transfer capability of the ground source heat pump. Furthermore, the summer conditions were simulated by using column-heat-source model, it turn out that the fluid temperature trends were similar with the experimental ones. The simulated inlet and outlet temperatures were 35.1°C and 30.4°C, which were in good agreement with the experimental temperatures of 35.1°C and 30.8°C. This work may provide some guides for the analysis of the thermal physical properties of the ground source heat pump and the integrated development of the Blue Silicon geothermal resources.
