This paper briefly introduced the basic principle and the frame structure of ADRC （auto disturbance rejection control） technology. It then summarized the characteristics of the commonly used intelligent pumping unit technology in the domestic oil field. To achieve the purpose of energy efficiency, this paper proposed a new algorithm by transferring the ADRC technology into the intelligent control cabinet of oil machine digital drainage. The field test demonstrated that this algorithm friendly improved the pumping oil machine intelligent adjustment function. The results show that ADRC technology in intelligent pumping oil machine has certain practical valuc.
