The invention discloses high-heat-conductivity cement mortar for a geothermal well and a preparation method for the high-heat-conductivity cement mortar. The high-heat-conductivity cement mortar comprises the ingredients in parts by weight: 100 parts of cement, 5-20 parts of graphite powder and 44-50 parts of water. According to the high-heat-conductivity cement mortar for the geothermal well andthe preparation method for the high-heat-conductivity cement mortar, through adding the graphite powder into the traditional oil well cement, the coefficient of thermal conductivity of the cement canbe increased while the requirements on well cementation construction are met, the efficiency of exploitation of geothermal resources is increased, and thus, the high-heat-conductivity cement mortar isapplicable to the technical field of development of the geothermal resources; and the high-heat-conductivity cement mortar is good in stability, relatively low in cost and good in environment-friendliness.
