摘　　要：地热资源是一种与石油天然气共存于沉积盆地且可再生的高清洁能源,在其开发利用过程中,需要关注地下温度场的变化,岩石的导热系数和比热是影响地下温度场变化的重要因素。华北油区潜山油藏岩石成分以石英和白云石为主,二者的含量在95%以上,其含量及变化是影响岩石热物理性质的主要因素,其中石英含量对岩石导热系数影响较大。根据测定结果,岩石导热系数变化区间为2.0 W/（m·℃^-1）-3.9 W/（m·℃^-1）,比热变化区间为0.8J/（g·℃^-1）-1.0J/（g·℃^-1）。另外,针对潜山油藏岩石的特点,重点开展了温度、压力、孔隙度等对岩石热物性的实验研究;在此基础上,结合并联电阻等热理论模型,提出了适用于华北油区潜山油藏的热物性计算模型,为地热开发利用方案设计提供理论依据。Geothermal resource is one kind of renewable and clean energy coexisted with oil and gas in sedimentary basin.It is necessary to study the variation of underground temperature in the exploration process of geothermal resource.Rock thermal physical property is the main factor affecting the variation of underground temperature.Rocks occurred in buried hill resource of Huabei oil area are mainly made up of quartz and dolomite of over 95%.Quartz content plays an important role in affecting the rock thermal physical properties.According to analysis,the heat transmission properties is ranging from 2.0 W/（m·℃^-1）to 3.9 W/（m·℃^-1）,and the specific heat properties is 0.8J/（g·℃^-1）to 1.0J/（g·℃^-1）.Experiments on relationship among temperatures,pressure,porosity and rock thermal physical properties are carried out.In combination with parallel resistance model,a thermal physical property calculation model is proposed in application to buried hill resource of Huabei oil area.
