摘　　要：:根据聚合物溶液在多孔介质中的渗流理论 ,采用节点系统分析法 ,推导出聚合物驱油井流入动态方程 ;给出了抽油杆与油管、柱塞与衬套、抽油杆与液柱、油管与液柱以及流体通过游动阀时摩擦力的求解方法 ;确立了悬点最大载荷、最小载荷、最小抗张强度、使用系数和排量系数等参数之间的关系 ;提出了聚合物驱有杆泵采油流出曲线计算方法 .运用编制的节点分析软件 ,对现场 13口聚合物驱抽油机井生产数据实现动态拟合 ,结果表明 :拟合冲程的平均误差为9.37% ,冲次平均相对误差为 3.0 8% .为此 ,应采用长冲程、慢冲次。This paper established inflow performance equation of well according to the flowing theory of polymer solution in porous medium. The non-Newtonian flow characteristic of product liquid was considered at the same time, the calculation method of friction load was given, including pumping rod and tubing, plunger and sleeve, tubing and liquid column, the force produced by the liquid through the travelling valve. It built the relationship among land top maximum load, minimum load, minimum tensile strength, serve coefficient and discharge coefficient etc, then got the method of calculating discharge curve in the polymer flooding and rod pump production. roduction system nodal analysis software about polymer flooding and rod pump well was applied, field production data of 13 pumping wells were imitated dynamically in polymer flooding, and example analysis was conducted. The result shows relative error of 10 wells were within 10%,agreeeable rate was 76.9%, average error of imitating stroke was 9.37%, average error of imitating stroke was 3.08%. In order to raise well production, long stroke, low and large pump diameter should be combined and used.
