Prediction for dynamic liquid level of sucker rod pumping using generation of multi-scale state characteristics in oil field production
Dynamic liquid level is an important parameter to reflect the liquid supply capacity of oil deposit. In the actual production site
dynamic liquid level is usually detected by the echo meter. This method is limited by the low detection efficiency
discrete measurement
and safety hazards. In addition to this
the existing prediction methods based on data-driven have difficulties in modeling due to the lack of historical data caused by various reasons. In response to the problem about lack of historical data
the multi-scale state characteristics which are closely connected with dynamic liquid level by analyzing the mechanism has been found out in this paper. Further
the state characteristics have been generated by using generative adversarial network (GAN). Simulation experiments have shown that the generated data can be used to establish dynamic liquid level prediction model and solve the problem about lack of historical data. On this basis
support vector regression (SVR) has been adopted as the modeling method and used in oil field production. Finally
the actual prediction results show that the proposed method is effective and meets the application requirements of oilfield engineering.
