WZ油田人工举升方式优选研究

Study on Optimization of Artificial Lifting Method in WZ Oilfield

针对WZ油田人工举升方式优选问题,基于油井自喷期末储层特征及生产要求,通过分析井下特征、油藏特性等影响因素,建立了工艺适应性评价指标体系,应用系统层次模糊优选模型选取电潜泵为WZ油田最优人工举升方式。结果表明,应用该模型优选人工举升方式,评价结果全面可靠、可操作性强,可为同类油田现场采油方式优选提供参考。

In order to choose the optimal artificial lift method in WZ oilfield,based on the reservoir characteristics and production requirements at the end of oil well flush stage,the technological adaptability evaluation index system is established by analyzing affecting factors such as downhole features,reservoir characteristics,etc.The System Hierarchical Fuzzy Optimization model is used to accomplish this task.As a result,the electric submersible pump is chosen to be the optimal artificial lift method for WZ oilfield.The result shows that the evaluation result of applying this strongly operable model to choose optimal artificial lift method is comprehensive and reliable,which can provide reference for similar oilfields in oil production mode optimization.
