Resumo

The effectiveness is considered of using the cooling capacity of liquefied gas to improve the operating reliability of cryopeg-containing saline soil infrastructure beds at gas-condensate fields. Mathematical modeling results are presented for a temperature field in soil beds in a four-layer soil massif (man-made embankment-frozen soil-saline thawed soil containing a cryopeg lens) when it interacts with a low-temperature thermal stabilizer. The rate of soil freezing was estimated for various coolant medium temperature, along with the efficiency of this method of thermal stabilization.
