Simulation of the temperature field of annulus multiphase flow in foam drilling

The physical property parameters and theological characteristics parameters of annular multiphase flow in foam drilling are sensitive parameters of temperature. Temperature distribution of annular multiphase flow affects its velocity field and pressure field directly. According to the realistic condition of foam drilling, this study, by use of Fluent simulation software, a mathematical model is established between vertical borehole and formation temperature field basing on flow dynamics and thermal conduction theory. So the temperature field of annular multiphase flow is simulated and the temperature field distribution of annular multiphase flow also is analyzed.
