英文摘要	The Lufeng (LF) 2-1 structure, which is the largest anticlinal structure developed in the Zhu I depression of the Pearl River Mouth Basin, offers high -quality source -sink matching with onshore CO2 emissions. In this paper, a 3D model using the TOUGH2/ECO2N tool was developed based on typical formation parameters obtained from a review of well and seismic structural data. Numerical results indicated that doubling the injection quantity does not result in a doubling of the CO2 distribution, which suggests the presence of nonlinear variations between the two variables. The CO2 plumes remain within the LF2-1 structural trap based on injection rates of either 1 Mt/y or 2 Mt/y. The maximum increase in formation pressure is less than 2 bars, which is 0.9% of the primary formation pressure. Therefore, the reservoir and seal properties of LF2-1 are optimal, which suggests that the prospect of injecting and storing a total of 40 Mt of CO2 is good. Overall, the LF2-1 may be used as a suitable offshore site for large-scale storage of industrial CO2 in deep saline aquifers. Additionally, the findings can guide site selection decisions in Guangdong Province for offshore CO2 geological storage demonstrations. (C) 2018 The Authors. Published by Elsevier Ltd.
