Description

technical field [0001] The invention belongs to the technical field of carbon peaking and carbon neutralization, and in particular relates to a complex terrain CFD calculation domain modeling method and geological storage of CO 2 Leak simulation and risk assessment system. Background technique [0002] Carbon capture, utilization and storage (CCUS) is an economical and effective measure to deal with global climate change, but due to the lack of understanding of the hazards of its potential leakage, it is easy to cause public panic and rejection of CCUS and become a large-scale One of the main obstacles to the promotion of CCUS. An oilfield in Northwest China, one of the CCUS pilot demonstration bases in my country, is a typical loess beam landform. In the demonstration project area, a comprehensive description of the route, the scope of potential carbon dioxide leakage and the level of harm, the promotion of CCUS technology and the national strategic goal of carbon neutrali...
