Abstract
The storage of large-amount CO2 captured from coal-fired power plant in deep saline aquifers can be an effective and promising measure for reducing emissions of greenhouse gases. High rate and long-term CO2 injection into the geological formation may cause multi-scale phenomena such as pressure buildup in large scale, CO2 plume in medium scale and salt precipitation in small scale. In this study, parallel computations are performed to determine the three-dimensional spatial effects during the injection of CO2 into closed systems. The study is aimed at investigating the propagation of pressure buildup, the development of CO2 plume and the impact of precipitation on the process due to the evaporation and capillary pressure. The results show that the region of elevated pressure is much larger than the CO2 plume size and the two types of salt precipitation close to the well both lead to the injectivity degradation and the declined transportation.
