Thermal infection analysis on hot water flooding dissociation frontal brim of natural gas hydrates

In order to study the gas hydrate thermal affection on hot water flooding dissociation frontal brim, the mathematical models of dissociation frontal brim counting hydrates saturation in the porous medium have been established and solved with an interactive method. The frontal brims of temperature probe and resistance from experiments fit well to the mathematical model matching and the errors are controlled less than 8%.The thermal factor infections of the hot water flooding temperatures and flooding rates on the dissociation frontal brim are analyzed.The errors of the temperature influence on the dissociation frontal brim are lesser than 8.71% and the influence errors of flooding rates on the dissociation frontal brim are 4.53%.The thermal infections on the hydrate dissociation frontal brim of hydrates can be lessened by rising injected hydrothermal temperatures with massive flowing rates.
