Abstract：Heavy oil has such characteristics as high content of colloid, asphalt and wax and high viscosity and it is difficult to exploit. With continuous development of oil field, process parameters of oil transfer pumps and heating furnace in oil gathering system deviate gradually from the design parameters, which results in deviation between actual working conditions and design conditions and large decrease in operation efficiency. Taking heavy oil surface gathering system as research object, with the minimization of operation energy as the objective function, and considering heavy oil inlet temperature, pump outlet pressure, blending ratio and flow rate as the constraining conditions, established is a mathematical model for heavy oil operation parameters optimization. According to characteristics of the model, applied is the LINGO software for programming and solving the optimization digital model and applied is the optimization digital model for optimizing operation parameters of heavy oil gathering system. Compared with that before optimization, the optimized heavy oil gathering system can save costs by 7.438% .
