Abstract: Oil and gas pipelines are one of the main means for oil and gas transportation over the world, and the development trend of their planning and construction is mainly affected by the development of oil and gas resources, as well as the national and regional energy policies. By quantitative and qualitative information mining, the global energy consumption structure and pipeline construction development in 2020 were sorted out, the current operation status of global oil and gas pipelines was analyzed, and the construction and development trend of global oil and gas pipelines in major regions of the world under the new situation was predicted. In the future, the construction of global oil and gas pipelines will be mainly affected by three factors: economy, politics and environment. It is predicted that the overall construction of global oil and gas pipelines will tend to be stable in recent years. Affected by the international environment, the construction progress of transnational pipelines is uncertain to a large extent, and fewer transnational pipelines can be completed and put into service on schedule. Besides, the pipeline construction in each country mainly depends on the economic development situation thereof. However, due to the dual impact of the economic downturn under the global COVID-19 pandemic and the energy transition under the guidance of "carbon peaking and carbon neutrality", it is expected that the local pipeline construction in the world will be concentrated in Asia-Pacific Region in the future. Meanwhile, the European and American countries and regions will explore to construct new hydrogen-mixed natural gas transportation pipelines or reconstruct existing gas pipelines for hydrogen-mixed natural gas transportation.(5 Figures, 3 Tables, 31 References)
