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。关键词：岩石热物性参数；导热系数；体积比热容；热力参数：含水馋和度

Abstract ; Through the study on distribution characteristics and influencing factors of rock thermal parameters,relational diagran of densi-ty-acoustic travel time,density-thermal econduetivity,density-volumetrie specifie heat capacity ,thermal conductivity-themal 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 eonductivity becomes larger;as water saturation decreased,volume spe-cifie heat becomes smaller. By adopting interval transit time,It can quickly calculate the thermodynamic parameters,such as the density of rock,thermal conductivity ,volume specifie heat,and themal diffusion coefficient, The variation trend of volumetrie specifie hcat 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. Keywords thermophysical parameters of rock ;parameters of thermal conductivity ;volume specifie heat ;thermal parameters;water saturation

春光油田在近5年的勘探、开发中取得了很大的成果，不仅在沙湾组继续扩大岩性油气藏的勘探战果，同时发现了断块、断层一岩性等多种类型油气藏圈闭，并迅速形成产能。春10井区为春光油田稠油蒸汽吞吐的2个热采区块之一，是某油田“十二
五"及以后新建产能的2个主力开发区块之一，为了确定合理的开发工作制度，通常在开发初期主要依靠数值模拟手段进行开发方案优化设计[1]，但是由于这2个稠油热采区块没有开展岩石导热系数、比热、密度、热扩散系数和热容量等热力参数测试，数值模拟时这些参数主要是参考胜利油田排6并区的测试结果[23]，无疑与春10井区地下实际情况还
