Abstract: Taking the land reclamation of China's petroleum and natural gas projects as the object, the research purposes are to provide more scientific guidance for the land reclamation of the oil and gas projects through analyzing the forms, damage and reclamation characteristics, and probing into the types of land reclamation projects and the key technical models using literature analysis, data summarization and zoning.The results show that the technical route and zoning method suitable for the land reclamation project regionalization of China's oil and gas projects are put forward.The three-level hierarchy of the land reclamation project area of China's oil and gas projects is determined, and the reclaimed area of China's oil and gas projects is divided into 9 first grade engineering types and 38 two grade engineering types.The key reclamation technologies and requirements for oil and gas projects covering engineering technology and biochemical measures are defined for different types of grade I zones.The research conclusion is to solve the basic problems such as zoning and key technologies of land reclamation projects in China's oil and gas projects, so as to provide technical support for land reclamation of oil and gas projects.
