摘要：

Temperature mapping provides important information for thermal characteristic analysis. There is no effective method for temperature mapping in porous media. A magnetic resonance imaging method is proposed to obtain temperature maps for hydrate formation in porous media in this study. The experimental results show that there is a high-temperature region around the hydrate formation zones. A threshold value of the mean intensity is necessary for temperature mapping. The effects of temperature on the mean intensity are negligible after the tetrahydrofuran solution completely forms hydrates. It is also shown that hydrate dissociation is confined by heat transfer and that there are three parameters affecting the hydrate saturation.
