针对全角变化率较大的油田,应用等效物理模型结合有限元分析的手段,提出了一种新的电泵机组高弯曲度油井的计算方法。通过建立等效物理模型,确定分析边界条件,并进行应力分析,得出电泵机组通过较大弯曲度井口时的安全系数。

A new calculation method for electric pumping units with high curvature oil wells is proposed by applying an equivalent physical model combined with finite element analysis for oil fields with large full angle change rate.By establishing the equivalent physical model,determining the analytical boundary conditions and performing stress analysis,the safety factor of the electric pumping unit through the wellhead with large curvature is obtained.
