The frequent failure of screw pump polished rod greatly restricts the development of its technology. Based on a large number of mechanical analysis and mechanical performance on material, the failure cause of the screw pump polished rod and stress condition at work are analyzed, and more accurate calculation model is built. It is pointed out that the curving alternate stress causes the failure of the polished rod. The dangerous sectionof the polished rod is on the outside surface at the bottom of the wellhead packing. Slight fissure first occurs here under combined action of the several stresses and ultimately causes the failure of the polished rod. Improvements on the processing and operating technology are also proposed in the hope of reducing the failure of the screw pump polished rod.</em></p><p class='subject'><strong>关 键 词：</strong><a
