摘　　要：通过开展岩石热物性参数分布特征及影响因素研究,春10井区首次建立了密度—声波时差、密度—导热系数、密度—体积比热容、导热系数—热扩散系数的关系图版。根据春10井岩石热力参数测试结果,研究认为导热系数和体积比热容随岩石粒度、密度增大而增加。与含水饱和度有一定关系:随着含水饱和度增加、导热系数逐渐变大;随着含水饱和度降低、体积比热容逐渐变小;油层胶结疏松,导热系数及体积比热容小;能够根据声波时差快速估算岩石密度、导热系数、体积比热容和热扩散系数等热力参数;体积比热容和含水饱和度的变化趋势也基本一致,具有"随着含水饱和度降低、体积比热容逐渐变小"的分布特点。该研究对春光油田稠油油藏实现经济有效开发具有重要意义。Through the study on distribution characteristics and influencing factors of rock thermal parameters, relational diagram of densi-ty-acoustic travel time,density-thermal conductivity,density-volumetric specific heat capacity,thermal conductivity-thermal diffusivity was firstly established in Chun 10 well. According to the test results of thermal parameters in Chun 10 well,it was proposed that,thermal con-ductivity and volumetric specific heat capacity increase with the increasing of particle size,density for rock. There is a certain relationship with water saturation ：with the increase of water saturation,thermal conductivity becomes larger;as water saturation decreased, volume spe-cific heat becomes smaller. By adopting interval transit time, It can quickly calculate the thermodynamic parameters, such as the density of rock,thermal conductivity,volume specific heat,and thermal diffusion coefficient. The variation trend of volumetric specific heat capacity and water saturation is basically the same,with the distribution characteristics of ＂decreasing water saturation and decreasing specific vol-ume heat＂. The study has important implications for achieve cost-effective development of heavy oil reservoirs in Chunguang oil field.
