HDPE内外防腐油管在空气泡沫驱井的应用

Application of HDPE Pipeline External Corrosion in the Well of Air Foam Flooding

常规N80新油管在空气泡沫驱井上应用约4个月就会腐蚀穿孔,针对空气泡沫驱井的腐蚀特点,优选HDPE内外防腐油管在注空气泡沫井上进行应用,在中原油田采油三厂3口空气泡沫驱井矿场应用表明,其结构简单,密封性能良好,施工方便,油管内外腐蚀情况大幅度减轻,,平均免修期达到523天,油管报废率由100%降低到35.5%。

Conventional N80 new tubing to the air foam flooding Inoue about tour months will apply corrosion perforation, for air foam flooding wells corrosion characteristics, Preferably HDPE and external corrosion in air injection foam tubing for application Inoue, Zhongyuan Oilfield three plants in three air foam flooding wells mine application shows that its simple structure, good sealing performance, easy construction, tubing significant reduction in internal and external corrosion, average exemption period reached 523 days, tubing scrap rate from 100% down to 35.5%.
