The energy consumption of oil collection increases rapidly after oilfield enters the stage of high water cut. Carrying out gathering and transportation at normal or low temperature can save cost and bring certain enterprise benefit. In order to judge whether the gathering and transportation can be carried out at normal or low temperature, the thermodynamic hydraulic calculation model is constructed and modified according to the field measured data. Then the thermally hydraulic coupling calculation is carried out to determine the gathering and transportation radius. The single factor sensitivity analysis method was used to rank the sensitivity of the factors influencing the gathering and transportation radius, and the radius chart is made. The results show that the modified thermo-hydraulic model can better predict the temperature and pressure drop, and the average error of the calculated and the measured value is 2.5% and 7.67%. The four most influential factors from strong to weak are starting point temperature, liquid yield, moisture content of mass and ambient temperature. The chart drawn by the factors provides the basis for the normal temperature gathering and transportation of the pipeline, so the required temperature at the start of the pipe can be determined by querying the chart.
