主　　题：Temperature model Oil reservoirs Fracturing horizontal wells Temperature distribution Sensitivity analysis 

摘      要：The application of distributed temperature sensors(DTS)to monitor producing zones of horizontal well through a real-time measurement of a temperature profile is becoming increasingly *** parameters,such as flow rate along wellbore,well completion method,skin factor,are potentially related to the information from *** on mass-,momentum-,and energy-balance equations,this paper established a coupled model to study on temperature distribution along wellbore of fracturing horizontal wells by considering skin factor in order to predict wellbore temperature distribution and analyze the factors influencing the wellbore temperature *** models presented in this paper account for heat convective,fluid expansion,heat conduction,and viscous dissipative *** temperature and wellbore temperature curves are plotted by computer iterative *** non-perforated and perforated sections show different temperature distribution along *** the study on the sensitivity analysis of skin factor and flow rate,we come to the conclusion that the higher skin factor generates larger temperature increase near the wellbore,besides,temperature along wellbore is related to both skin factors and flow *** response type curves show that the larger skin factor we set,the less temperature augmenter from toe to heel could *** addition,larger flow rate may generate higher wellbore temperature.
