Statistics and optimization of pumping rod break in the Tahe oil field

摘要: 近年来抽油杆断脱成为塔河油田抽油机井检泵作业的主要因素,严重影响了油井正常生产,造成大量经济及产量损失。通过统计分析认为,交变载荷大造成的疲劳断以及泵挂深导致的抽油杆偏磨断是造成抽油杆断脱的主要原因。针对断脱的主要因素,在2015年开始从优化设计、加强管理、引入新技术等3个方面进行了综合治理,降低了杆断检泵频次,年节约修井费用181万元,年减少产量损失439 t,取得了较好的效益。Abstract: In recent years, sucker rod break has become a major factor influencing pumping operation in the Tahe oil field, which seriously affected the normal production of oil well and caused a lot of economic and production losses. Through statistical analysis, the fatigue caused by alternating loads and the deflection of sucker rod are the main reasons for break. Started in 2015, we carried out optimization design, strengthened management, and introduced some new technologies to reduce break frequency, hence saved costs of RMB 1.81 million per year, reduced production loss of 439 tons.
