The beam pumping unit is widely used in oil fields as an oil extraction machine. However, due to its structural characteristics and the changing conditions of underground reservoirs, there are many factors affecting the efficiency of the beam pumping unit. How to quickly and accurately reflect the inefficient factors, and whether the efficiency of the pumping unit is reasonable, it is an urgent problem to be solved. In this article, we propose a pumping unit efficiency evaluation model consisting of the scoring model and the predictive model. The scoring model reflects the inefficient factors, and the predictive model judges whether the efficiency of the pumping unit is reasonable. Finally, the actual production data of the oilfield were used to verify the effectiveness of the method.

基于主成分回归分析的游梁式抽油机高效评价模型

游梁式抽油机作为抽油机械广泛应用于油田。但由于其结构特点和地下水库条件的变化，影响游梁式抽油机效率的因素较多。如何快速、准确地反映低效因素，以及抽油机的效率是否合理，是一个迫切需要解决的问题。在本文中，我们提出了一种由评分模型和预测模型组成的抽油机效率评估模型。评分模型反映低效因素，预测模型判断抽油机效率是否合理。最后利用油田实际生产数据验证了该方法的有效性。
