基于TOUGH2模拟CO2地质封存对地层温度的影响
Simulation of CO2 Geological Storage Research on the Effect of Formation Temperature Based on TOUGH2
摘要
Abstract
The three-dimensional model is established with the numerical simulation software TOUGH2 of flow and heat migration, through a constant speed with long time of injecting fluids containing CO2 to simulate CO2 geological storage research on the effect of formation temperature.The results show that the formation temperature is in equilibrium before CO2 geological storage and the original balance is broken after sealing up.The higher the formation permeability is, the more conducive to the exchange of temperature.The temperature of whole formation undergoes the process from unsteady state to steady state, and because the exchange of formation temperature is restricted by the energy conservation, the final temperature of the whole formation is about at the initial time and the middle temperature of the lower formation temperature.The injected fluid continuously has a limited influence on the formation temperature, and the formation temperature changes rapidly in the early, the late change rate gradually slows down.关键词
