Аннотация:The role of gas fluids migration through permafrost is stated due to the several gas emission craters formations that
are located in the north of Western Siberia. These phenomena are the result of physical explosive processes. Authors
consider the general sequence of the four stages and formation of the four zones of: 1 - gas fluids occurrence; 2 - gas
fluids transition; 3 - gas fluids accumulation; 4 - plastic deformations. The proposed source of the gas fluids formation
is decomposition of relic gas hydrates in permafrost. This assumption is based on numerous gas emissions during the
wells drilling at the Bovanenkovo field. Various scenarios for the development of fluid dynamic processes in permafrost
are considered. The fluid dynamic concept is also applicable for the gas emission craters formation due to free gas
contained in permafrost and due to gas flows underneath the permafrost.
