The frozen soil area contains abundant oil and gas resources, and the exploitation of the resources and the construction of a large amount of oil and gas pipeline projects are required. In the United states, Canada and former Soviet Union, a plurality of oil and gas pipelines are laid in permafrost regions, and a great deal of construction and operation experiences of oil and gas pipeline engineering in the permafrost regions are accumulated. Oil pipelines from Haiensis to Filbanks in Alaska were successfully laid in 1956; in 1977, Alaska piping of 1280km in length began to run; in 1985, oil pipelines of Roman wells located in discontinuous permafrost regions in Canada were successfully laid, and crude oil was transported from the Roman wells to northern horses in Alpotter province. In the early 70's of the last century, oil pipelines began to be laid in permafrost areas in the former soviet union.
China also builds a large number of oil and gas pipelines in permafrost regions, for example: in 1977, a Gela finished oil pipeline located in permafrost regions of Qinghai-Tibet plateau is built and put into production; in 2001, an acerola gas pipeline and a multi-line project which pass through rubber mountains and ridge-pulling island-shaped permafrost areas are successively built; in 2002, the first line, the second line and the third line of the west-east gas transmission engineering crossing the Tianshan mountain and the Qilianshan are sequentially built; in 2010, a large-caliber long-distance crude oil pipeline passing through the great Xinghan and Anshan mountains in the northeast is built and put into production.
