Analysis of borehole stability in gas drilling using a thermal elastoplastic coupling model

Abstract Gas drilling causes lower pressure in the borehole and the Joule‐Thomson effect to occur at the bit nozzle, resulting in a temperature distribution in the borehole different from that in the original formation. The borehole temperature is far lower than the original formation temperature ne...
