摘要
针对樊学油田地面集输系统结垢问题，开展了不同层位的注入水、地层水水质分析，配伍性研究及垢样分析等系列实验；明确了结垢机理及垢样组成，并优选出阻垢剂，阻垢率达到86％以上。现场进行了4个增压点和1个转油站加药试验，跟踪结果表明：加药后结垢速率降低8～10倍，防垢率80％以上，防垢效果明显。
According to the Fanxue oilfield＇s scaling problem of surface gathering system, carried out different horizons of injected water, formation water, water quality analysis, re- search of the compatibility and fouling sample analysis such as a series of experiments; clear the scaling mechanism and scale, and optimize the scale inhibitor, scale inhibition rate reached more than 86 %. Site of the 4 pressure points and 1 oil transferring station chemical test, tracking results show that： dosing after scaling rate to reduce 8-10 times, antiscale rate above 80 %, scale effect is obvious.
