According to the particularity of high viscosity and high viscosity oil wells, the physical properties of high viscosity and high viscosity crude oil in Dagang Oilfield are analyzed based on a large number of experiments. Based on the experimental data, the parameters of heating, water mixing and other parameters In the optimization design and calculation, a system optimization method considering both economic benefits and maximum system efficiency is put forward, and the adaptability of the optimal design method for improving the system efficiency to Shuanggao Wells is enhanced. By optimizing the design results It is concluded that the optimized design scheme with the highest efficiency of high condensing and high viscosity oil well system is not the conclusion of the optimal scheme. It is instructive to improve the efficiency of the mechanical extraction system of high pour point and high viscosity oil wells adopting supporting measures.
