锦州油区注水管网长期运行,大量污垢粘附在管壁上,对水质造成二次污染,致使井口水质不达标,严重影响注水效果。本文研究利用空穴射流清洗技术对管壁进行物理清洗,该技术具有清洗速度快、不垢堵、不卡阻、不磨损、低压清洗、安全可靠等诸多优点,有效地解除了水质的二次污染问题。清洗后,井口水质综合达标率由31%提升到83%。
Jinzhou long-term water injection pipe network, a large number of dirt adhering to the pipe wall, resulting in secondary pollution of water quality, resulting in wellhead water quality standards, seriously affecting the water injection effect. In this paper, the use of hole jet cleaning technology for physical cleaning of the pipe wall, the technology has the advantages of fast cleaning, no blocking, no blocking, no wear, low pressure cleaning, safe and reliable, effectively relieving the secondary water quality pollution problem. After cleaning, the wellhead water quality compliance rate increased from 31% to 83%.
