摘要:针对强碱三元复合驱集输系统出现的淤积结垢问题及对生产的影响,从各节点入手,跟踪分析淤积结垢状况,淤积物为原油、聚丙烯酰胺降解物、碳酸盐垢和硅垢等。对现场应用的各项清防垢措施进行总结,并在此基础上进一步提出解决三元复合驱淤积结垢的措施及建议,单井管道应采用“管道冲洗”、站间掺水管道宜采用“空穴射流”、站内掺水热洗系统采用“高压射流”等物理方法,上述方法是目前治理淤积结垢较为有效办法。

To solve the problem of siltation and scaling of the ternary flooding transportation system, we start from the individual pitch point to track the siltation and scaling conditions,the deposits are crude oil, polyacrylamide degradation products, carbonate scale and silicon scale. We have summarized the measures taken to clean the siltation and scaling on site, based on which we have proposed measures to solve this problem in ternary flooding transportation. Single well pipeline should adopt "pipe flushing, station between watering pipes should be used with hole cavitation jetting, the station watered heat washing system should adopt the high-pressure jetting and other physical methods, the method is currently controlling the deposition fouling more effective way.
