摘要
在定向井、水平井中使用有杆泵机械采油方法时 ,需要在抽油杆柱上安装扶正器。文中通过合理简化 ,推导了扶正器安放间距的计算公式 ,提出了一套在定向井中进行抽油杆扶正器分布设计和摩擦力计算的数值计算方法 ,并编制了相应计算机程序。该方法简便、实用 。
When using the mechanical recovery method with sucker rod pump in directional and horizontal wells,it needed install to centralizer on sucker rod string.The paper deduced the calculation formulas of distance between two stabilizers through reasonable simplify,put forward a set of numerical calculation procedure of the frictional force calculation and the stabilizer distribution design of sucker rod string in directional wells,and worked out the appropriate computer programs.The procedure is simple,convenient and practical,and can meet the demand of engineering.
