| Abstract: | In order to inquire the laws of hot water flooding dissociation of natural gas hydrates in porous medium,experimental equipments on dissociation of natural gas hydrates have been design and laws on dissociation frontal brim of hydrates are inspected through thermal elect-dipole and resistance in these experiments.Results from massive experiments show that three steps characteristics(reservoir bed temperature rise,equal dissociation and frontal brim breach) are exhibited distinctly.In order to reveal substance of dissociation of natural gas hydrates,model on dissociation moving frontal brim of hydrates is built.Fit values and experimental values of temperature and electric resistance are analyzed contrast.It shows from fit values and experimental values that correlation express preferable,but more times of dissociation was needed for fit value than experimental value to break the dissociation frontal brim of natural gas hydrate. |
