Abstract

In order to find the injection wells with abnormal energy consumption, the energy consumption evaluation has been carried out for them. Based on the law of energy conservation, the model of single-pump corresponding to single-well is established, and the linear relationship between input power and power consumption per unit injection rate of single wells is deduced. Therefore, the straight line intercept method and the unit consumption energy saving rate method are put forward to evaluate the energy consumption of water injection systems and injection wells respectively. The results are verified by data from some water injection systems in oilfield-A in northwest and oilfield-B in northeast China. The results show that, according to theoretical analysis and field data, there is a linear relationship between the input power and the power consumption per unit of injection of a single well. The slope and intercept of straight line reflect the energy consumption of injection system and water injection well. The evaluation results of the injection system using the linear intercept method are basically consistent with the traditional system efficiency method. In addition, the evaluation of the energy consumption of injection wells by the unit consumption energy saving rate method can help to identify the injection wells with abnormal energy consumption. Combined with the actual situation on the site, the causes can be analyzed and the corresponding measures are taken to improve the efficiency of injection system.

Key words： injection well; energy consumption evaluation; single pump single well model; linear intercept method; unit consumption energy saving rate method
