Developing and Interpretation of a novel Temperature Distribution Model in Wells with Multi Pay Zones

obtaining temperature and pressure profile in the wellbore is essential for more accurate multiphase flow simulation. Also , temperature measurements have the potential to be revealing in the reservoirs and the wells production performance. In this paper a novel temperature and for all the real conditions such as non-homogeneous multiphase flow and phase changes which have been ignored by previous authors. then a sensitivity analysis has been performed to examine the achievability of a relationship between inflow profile and amount of temperature change in the wellbore . in addition , effects of production parameters on temperature and pressure distribution in well bore have been in vestigated. several example cases reflect the temperature model's utility . the temperature profile in the well bore distinguishes inflow intervals by showing a noticeable deflection across these sections. the intensity of temperature change in production section of wellbore depends on type and amount of inflow. also from a sensitivity ananlysis for phase fractions, it has been found that while increasing the GOR in the wellbore results in decreasing the temperature more WOR causes warming of the wellbore.
