聚合物驱油井见聚合物后 ,检泵周期大大缩短 ,主要原因是杆管偏磨 ,致使抽油杆断脱和油管损坏 .以抽油杆在运动过程中的受力模型为基础 ,综合考虑在不同剪切速率下聚合物溶液表现出的不同流变性这一规律 ,计算了聚合物驱油井采出液的粘度 ,进而确定了抽油杆运动中所受的各项阻力 ,找出了杆管偏磨的原因 ,并提出了解决措施 .通过实际应用 ,检泵周期延长了一倍以上 . Polymer flooding wells see the polymer, the pump cycle greatly shortened, the main reason is the partial wear of the rod, resulting in sucker rod breakage and tubing damage.Based on sucker rod in the movement of the force model based on a comprehensive consideration At different shear rates, the polymer solution showed different rheology. The viscosity of the oil in the polymer flooding well was calculated and the resistance of the sucker rod movement was determined. The reason of tube partial wear, and put forward the solution measure.Through the practical application, check the pump cycle more than doubled.
