China’s dependence on crude oil is high.Since the conflict between Russia and Ukraine，the energy security problem has attracted great attention.The large coastal crude oil terminals play an important role in the national crude oil supply guarantee system.Based on the situation of crude oil supply，demand and transportation in foreign trade，the layout and capacity adaptability of large coastal crude oil terminals are analyzed，and the large crude oil terminals are put forward to meet the needs of Chinese petrochemical industry development and crude oil reserves in general，but the characteristics of regional imbalance are prominent，including Liaoning coastal capacity is sufficient，Shandong coastal capacity is tight，the capacity of the Tianjin-Hebei coastal area，the Yangtze River Delta，the southeast coastal area and the Southwest coastal area is moderately advanced.Considering the changes of crude oil supply and demand and the situation of the“14 th Five-Year Plan”large-scale crude oil terminal project，it is predicted that the capacity of large-scale coastal crude oil terminals in the future will be fully guaranteed.
