摘　　要：对吉林农安油页岩进行了TG分析,发现在N2气氛下其热失重可分为低温失重段（30℃-300℃）、中温失重段（300℃-540℃）和高温失重段（540℃-800℃）,且中温失重段为主要失重阶段。对农安油页岩进行了热物理性质试验,发现其热物理性质具有各向异性,且水平层理方向的热物理性质系数更大;导热系数和体积比热容随温度升高变化趋势一致,而热扩散系数随温度升高变化不大。It is essential to study on its properties for the better development and utilization of oil shales.Through TG analysis on Nong＇an oil shale in Jilin,the authors found that under N2 atmosphere,their thermal weight loss was divided into three different periods,including the low temperature weight loss period（30℃ - 300℃）,the medium temperature weight loss period（300℃ - 540℃） and the elevated temperature weight loss period（500℃- 800℃）,in which the medium temperature weight loss period was predominant.Thermal physical properties of Nong＇an oil shale were carried out,as a result,thermal physical properties were proved to be anisotropic and these properties for horizontal bedding were higher than those for vertical bedding.In addition,heat conductivity coefficient and volumetric specific heat capacity showed a similar tendency with the increment in temperature,while thermal diffusivity didn＇t present a remarkable change.
