陇东油田中城壕油田悦29区、玄马区和城63区以及五蛟油田里37区均为腐蚀严重区块。其中悦29、玄马和里37区属采出水回注区块,井筒问题复杂,维护性作业总量高,作业频次高,治理形势严峻。使用耐磨抗腐蚀性能高的合金球、球座结合悦29区井筒问题中泵故障高发,试验配套合金球、球座取得良好效果;在玄马、城63和里37区推广使用,总结出了一套有效的编号追踪分析法,得出适宜推广区块的标准,实现高腐蚀区块降低泵故障率,发展成为成熟的井筒治理技术。
Longtong Oilfield Zhongchengmo Oilfield Yue 29 District, Xuan Ma District and City 63 District and Wujiao Oilfield 37 are serious corrosion block. Among them, Yue 29, Xuan Ma and Li 37 belong to the reclaimed water recovery block. The wellbore problems are complex, the total amount of maintenance work is high, the frequency of operations is high, and the governance situation is grim. The use of alloy ball with high abrasion and corrosion resistance performance, ball seat combined with Yue 29 area wellbore problems pump failure, test supporting alloy ball, ball seat achieved good results; in Xuan Ma, City 63 and Lane 37 area to promote the use of summed up A set of effective number tracking analysis method has been put forward, which is suitable for popularizing the block standard, reducing the failure rate of the pump in the highly corroded block and developing into a mature well management technology.
