Optimization of Viscosity Reduction Technology by Electric Heating for Petroleum Pipeline

In order to solve the difficulty of high energy consumption during heavy oil lifting, the mathematical model of using electrical heating petroleum pipeline technology to reduce the viscosity is build, the bore temperature field of pipeline is calculated, and the optimization technology of electric heating pipeline is given. It is shown that the energy consumption of lifting could be significantly reduced after optimizing the heating depth and heating power to the electric heating system. The well A was taken as an example to verify this optimization calculation. The results indicated that the optimal heating depth is 890 m and the optimal heating power is 29.6 kW. After the optimization, the energy consumption fell down 7.5%.The optimization technology of electric heating pipeline given by this paper can make the high energy consumption equipment run with lower energy.
