METHOD OF MONITORING TEMPERATURE ANOMALIES IN PERMAFROST GROUND OF A LINEAR OBJECT TRAIL Russian patent published in 2018 - IPC F17D5/00 

FIELD: measuring equipment.

SUBSTANCE: method of monitoring temperature anomalies in permafrost ground of the line of the linear facility relates to the following areas: oil and gas industry, geophysics, construction, etc. Primary field of application is monitoring of temperature anomalies in permafrost ground of main oil pipelines. According to the signals from the temperature sensors in each thermowell, a layer with the defrost boundary of the permafrost ground is determined. Determine the weighting coefficients α_i for the upper layers of the permafrost ground, a layered temperature model is found θ_j. Determine the weighting coefficients β_i for thermo-landings of a site. Weighted temperature model is found θ_uh site. Find temperature deviations Δ_j. In accordance with the a priori data, the maximum permissible value Δ_md and compare the temperature deviations Δ_j with her. In case of excess, each time they form the necessary information on temperature anomalies in permafrost ground.

EFFECT: technical result is an increase in the efficiency of the functioning of linear objects located in the permafrost ground zone, as well as a significant increase in the probability of identifying dangerous geocryological processes.
