摘要: 通过对塔河油田采油二厂杆断裂情况、监测的功图载荷及杆柱应力评价、注气及断杆腐蚀情况、断杆前的生产异常情况的综合分析,结合送检断裂杆的失效分析报告,认为抽油杆断裂主要影响因素是高负载、高交变载荷下的疲劳断裂以及注气及硫化氢腐蚀;通过进一步分析认为:泵型的合理选择、泵深的合理确定、杆柱设计的优化、严格的生产管控及抽油杆的合理优选可以有效地降低抽油杆断裂几率.

Abstract: Through the comprehensive analyses of the rod fracture situation, the diagram of load monitoring, the rod stress evaluation, the fractured sucker rod corrosion and the abnormal situation before broken, combined with the failure analysis report of fractured rod, the main influencing factors of sucker rod fracture mainly include high load, high alternating load and corrosion of hydrogen sulfide and injection gas. The reasonable choice of pump and pump depth, the optimization of rod string design, the strict production control and the reasonable optimization of pumping rod can effectively reduce the probability of sucker rod fracture.
