Introduction to China Petroleum Pavilion: Theme: Petroleum, extending urban dreams. The outer wall of the exhibition hall is woven vertically and horizontally by oil and gas pipelines, which is very contemporary and industry-specific. Building materials adopt new green petroleum derivatives and explore the wide range of uses of petroleum and petrochemical products. The nearly 4,000-square-meter exterior wall of the building will be transformed into a large LCD screen, which will be transformed to the accompaniment of musical fountains around the exhibition hall. Multimedia means combined with the characteristics of the petroleum and petrochemical industry create various virtual scenes with magic seconds, bringing visitors closer to the oil.
