摘要

An experimental program to determine the effective thermal conductivity and diffusivity of six cementing systems used in the completion of Mexican geothermal wells was carried out in the temperature range from ambient to 220°C. The classical line-source method (CLSM) and the Jaeger (JM) methods were used for this purpose. The experimental system was calibrated by measuring the thermal properties of fused-quartz samples used as standard. An experimental procedure for preparation of the cement samples was also developed. It was found that thermal conductivity and specific heat capacity depend on each particular cement system and increase with temperature for most cement systems while thermal diffusivity decreases with temperature for most systems. Uncertainties of 4% and 9.5% were found for thermal conductivity determined by the line source and Jaeger's methods, respectively, while the Jaeger method yielded uncertainties of 11.8% and 8.5% for thermal diffusivity and specific heat capacity respectively.
