| This subject mainly selects the Pubei oilfield representative oil wells through statistic analysis, explores the reasonable limit of control parameters on the base of field test, and observes the state oil pipeline flow. It also selects the Corresponding flow model combined with the relevant document of flow model, and compiles the calculation software of the oil temperature drop and oil pressure drop. Then it adjusts the control parameters of oil wells through the flow automatic control system and corrects the calculation software. At last through the calculation software of oil temperature drop and oil pressure drop to determine the Pubei oilfield reasonable production parameters limits of the oil collecting system, According to temperature and pressure limits of a reasonable subject, determine the best out of each well watered amount higher than the results of individual oil wells, control the amount of single well mixed with water; higher than the results for the majority oil wells, control mixed with water temperature and watered amount, by optimizing the parameters of the Pubei oilfield gathering system running, the Pubei oilfield in 2009 natural gas saves of 498.27 x 104m3, power saves of 89 x 104kW ? h.
