摘 要：正Coupled processes in porous media impact drilling and borehole *** coupling of the matrix deformation,and fluid and heat diffusions results in a time dependent response in the *** the drilling of an oil or gas well, temperature gradients between the drilling mud and the formation can significantly change the pore pressure and stress distributions around the borehole.A general theory of thermoporoelasticity is developed that fully couples the three processes: mechanical,hydraulic,and thermal in porous media
