北京地区基岩地层热物性参数特征
|
摘要
北京地区迄今为止尚未开展过系统性的基岩地层热物性参数测量工作.为给北京及邻近地区开展地热学研究与资源评价提供依据和参考,在北京周边山区标准地层剖面上采集了548件岩石样品,覆盖了前新生界各组不同岩性的沉积地层及大部分岩浆岩地层,开展了热导率、比热和热扩散率测试,分析了基岩地层的热物性参数分布特征.结果表明:9种不同岩性岩石的热导率平均值为2.231~4.330 W/(m·K),岩石比热平均值为1.632~2.029 MJ/(m~3·K),热扩散率平均值范围为1.166×10~(-6)~2.481×10~(-6)m~2/s.热导率和热扩散率最大的地层是蓟县系白云岩、页岩组合,最小的是白垩系的火山岩和砂砾岩组合.比热最大的地层是三叠系的粉砂岩、凝灰质砂岩和砂砾岩组合,最小的是蓟县系白云岩、页岩组合.全区热导率、比热和热扩散率与岩石地层的矿物组分、孔隙度、温压条件等有关.全区岩石热导率(K)与热扩散率(κ)值存在线性关系,相关方程为K=0.5834κ-0.0255.
Thermal physical parameters measurement of bedrock hasn't been performed and analyzed systematically so far in Beijing.In order to provide the basic data for geothermics study and resource evaluation in Beijing and its neighboring area,a total of 548 samples of rock with different lithologies were collected from standard stratigraphic section,which included all of sedimentary strata and magmatic rock stratum Pre-Cenozoic,then properties were measured and analyzed comprise thermal conductivity,specific heat and thermal diffusion.The results show that the average value of nine different rocks are 2.231~4.330 W/(m·K)(thermal conductivity),1.632~2.029 MJ/(m~3·K)(specific heat),and 1.166×10~(-6)~2.481×10~(-6)m~2/s(thermal diffusion),respectively.The largest thermal conductivity and thermal diffusivity is dolomite and shale combination of Jixian system,and the smallest is cretaceous volcanic rocks and glutenite.The largest specific heat of strata is triassic system which includes sandstone,tuffaceous sandstone and glutenite,and the smallest is dolomite and shale combination of Jixian system.The thermal conductivity,specific heat and thermal diffusion are mainly controlled by their mineralogical compsitions,porosity,temperature and pressure,etc.There is a linear relationship between the thermal conductivity(K)and the thermal diffusivity(κ)with correlation equations K=0.5834κ-0.0255.
