Abstract: With the development of social economy and the improvement of awareness for energy conservation and emission reduction， upholding the philosophy of green development is a scientific reflection of the development law，as well as a positive response to the changes in the global ecological environment. Currently，the issues of industrial power consumption，power conservation，and improving the efficiency of power distribution network have aroused extensive attention of the whole society. This paper analyzes the impact on the power factor of the energy efficiency indicator of the power distribution network during actual production based on the load change and the distribution characteristics of main equipment in the mechanical recovery process of heavy oil fields，and makes discussions in close combination with the power consumption characteristics of oil fields. By applying such technologies as 3-phase equilibrium，inactive compensation and harmonic control，rational planning is made，compensation measures are taken，and effect is validated to ensure the effective improvement in power factor. Thus，a solution that combines the power consumption demand，energy efficiency management and smart grid technology of oil field together is formed to realize the production goal of energy conservation and consumption reduction by optimizing the distribution network environment，obtain satisfactory power conservation and emission reduction effect by improving the efficiency of distribution network，and practice the green development philosophy of energy and power conservation.
