Under the background of the “carbon peaking and carbon neutrality goals”, the salt cavern is an important place for geological storage and carbon sequestration. The limited knowledge of the quantity and quality of the salt cavern and immature investigation technology constrains the development and utilization of salt cavern. After analyzing the geological exploration reports on major salt mines, reserves reports, enterprise annual reports, and research articles, a scientific understanding and basic judgment of the amount and utilizability of salt caverns in China are obtained; a technical system of salt cavern resource survey is established through a test with comprehensive detection technology in the concentrated area of salt cavern. The results show that salt cavern resources in China are characterized by abundant reserves, wide distribution, feasible burial depth, and convenient utilization on large scale. The most abundant salt cavern resources occur in the east and central regions. The national salt cave
