METHOD OF DESIGN POSITION CONTROL OF CONNECTION PIPELINES OF GAS OR OIL PRODUCERS WITHIN PERMANENTLY FROZEN SOIL AREAS Russian patent published in 2010 - IPC E21B36/00 E02D27/35 

FIELD: oil and gas industry.

SUBSTANCE: invention concerns oil and gas industry and can be used in construction of supporting structures of above-ground connection pipelines of gas and oil producers on permafrost soils. The method involves drilling of a producing well, mounting of production well-control equipment thereon, well axes layout for pile abutments wherein after drilling near to the producing well, the pile abutments are mounted, and securing of a proper pipeline on each pile. The well axes of the pile abutments nearest to the producing well are marked at such distance from the producing well to prevent permafrost thaw, or to ensure their security throughout the entire operating life of the producing well by involving seasonal cooling devices. The area of intensive thermal effect of the producing well is determined taking into account temperature of a product in a producing well head, operation time, presence and capacity of the seasonal cooling devices. The method can be applied both in construction of new producing wells and in repair of operating producing wells.

EFFECT: throughout the entire operating life, the method provides design position of connection pipelines by keeping of stability of the pile abutments within permanently frozen soil areas exposed to thermal action of the producing well.
