Thermal properties of rocks are the important parameters for studying the present-day geothermal regime and tectono-thermal evolution of the sedimentary basins,which would also provide fundamental data for the assessment and exploration of oil and gas resources in this basin.The Lower Yangtze area of the South China is considered as one of the preferred areas for shale gas exploration and development in China.The thermal properties of shales are of great significance for the exploration of shale gas resources in this area.However,the measured properties data of shales in this area are still rare,limiting our understanding of the geothermal field and resource assessment.In this study,thermal properties of 18 mudstone and shale samples from the Lower Yangtze area are measured,including the thermal conductivity,density and radiogenic heat production as well.Our results show that the values of thermal conductivity of shales generally range from 1.500W/(m·K) to 3.000W/(m·K)with a mean of 2.174±0.682W/(m·K);while the values of radiogenic heat production basically vary from 1.00μW/m3 to 2.50μW/m3 with a mean of 2.04±0.86μW/m3.Compared with other sedimentary rocks,the shale has unique thermal properties,and is characterized by a lower thermal conductivity and a higher radiogenic heat production.The thermal properties of the samples with same or similar lithology are somewhat different,indicative of their unavailability for distinguishing lithological types alone.Additionally,the estimated present-day subsurface formation temperature distribution pattern of the whole Yangtze area shows that the temperature gradually decreases from the Jiang-Zhe-Wan area(the Lower Yangtze area in the east)to the Upper Yangtze area in the west,but the temperatures in the southeastern Sichuan and the Chuxiong basins are relatively higher,which is the combination of local tectonics and variation in thermal properties.Generally,the shale bed is just like a heat insulation layer,owing to its low thermal conductivity,and this thermal blanket effect can result in anomalous high temperature in the underlying formation but anomalous low temperature in the formation above.Anomalous temperature caused by such unique thermal properties of shale rocks would change the distribution of temperature field in the deep formation,thereby affecting the source rock thermal maturation evolution.These unique thermal properties of shales and associated thermal effects must be taken into account in the assessment of shale gas resources in China.
