| 简介 |
The method involves choosing rare gas and to-be-stored species diffusion models. Samples of fluid present in an area of subsurface are removed, and concentration of rare gas within the samples is measured prior to and after injection of gas into formation of subsurface. Effective diffusion coefficient of the model is modified, and a ratio between a rare gas diffusion coefficient and the modified coefficient is deduced when concentration of the gas increases. The ratio is applied to the model of species, and a quantity of the species dissolved at an instant (t) is determined from the ratio. |
