浅层地温能岩土热物理性质及地温场特征
Study on Thermal Physical Properties and Characteristics of Geothermal Field of Shallow Geothermal Energy in Jvxian County in Shandong Province
摘要
Abstract
Taking Jvxian county in Shandong province as an example,thermal physical parameters of dif-ferent rock and soil masses in shallow geothermal energy in Jvxian county have been summarized based on field investigations,thermal physical testing of rock and soil samples,water sample testing,on-site ther-mal response testing and geothermal monitoring.The thermal diffusivity and specific heat capacity of rock and soil mass are negatively correlated with their density,while the coefficient of thermal conductivity of rock and soil mass is positively correlated with their density.The chemical interaction between shallow ge-othermal water and rocks has not reached equilibrium,and the water-rock reaction is weak.The spatial distribution characteristics of shallow geothermal fields indicate that the northern Quaternary system is thicker and has a higher ground temperature,while the southwest is dominated by Hongtuya group and Tianjialou group,which exhibit lower ground temperatures.This study lays the groundwork for the adap-tive evaluation of shallow geothermal energy heat exchange methods in Jvxian county and for estimating shallow geothermal energy resources.It will provide a significant reference value for the design and opera-tion of ground source heat pump systems.关键词
