| Summary: | Abstract The paper is devoted to complex experimental studies of methods to reduce the rate of permafrost thaw during the construction of oil and gas wells in the fields of the Krasnoyarsk territory. Laboratory physical and chemical studies on the development of drilling fluid formulations for drilling in permafrost conditions were carried out. The most significant results were obtained for clay-polymer solutions with the addition of ethylene glycol and propylene glycol. It was shown that it is possible to control the thermal, hydration and filtration characteristics of drilling fluids by introducing ethylene glycol and propylene glycol without deterioration of their rheological properties. |
