FIELD: oil and gas industry.
SUBSTANCE: invention is related to oil and gas industries and may be used during development and operation of deposits in the area of permafrost formations. Device for thermal stabilisation at wellhead area includes an aggregate of heat stabilisers placed around the well and connected through the common collector in the upper part with a condenser. At that the lower part of heat stabilisers is also united by the common collector, and finned surface factor and the area of unfinned condenser surface are selected in order to meet performance of the specified mathematical expression.
EFFECT: provision of unconstrained operation and repair of the well at effective stabilisation of thermal state in the wellhead area in permafrost formations.
