Through actual case study, the pressure distribution between sucker rod and tubing is analyzed. It is pointed out that lowering the kick-off point and the bore-hole curvature is an effective way to improve the working conditions of sucker rod and tubing. 通过实例分析了抽油杆与油管间挤压力的分布,指出降低造斜点和井眼曲率是改善抽油杆与油管工作条件的有效途径。
