【摘要】 介绍了垢对油田加热炉安全经济运行造成的严重危害及其成因．分析研究了有机磷酸盐与聚合电解质的防垢机理．在此基础上，提出了命名为ＧＤ－９５３复合型化学防垢剂．大量的静态与动态试验结果表明，该复合型化学防垢剂，可产生良好的协同效应，具有抗高温、高钙等独特的防垢效果．在９５℃和８５℃条件下，其防垢率明显高于现有的最好防垢剂．对于含油污水，投该防垢剂（３～５）ｍｇ／Ｌ时，其防垢率就达１００％．对高钙水，投加低剂量防垢剂时，仍有较好的防垢效果．更多还原

【Abstract】 From the anti scale mechanism of organic phosphate and polymerized electrolyte,a compound chemical anti scale agent(named with GD953) is proposed,and experiment results show this compound chemical anti scale agent can produce good results and it has good performance of unique anti scale effect at high temperature to high calcium water. Its anti scale rate is evidently higher than that of the existing best anti scale agents when the temperature is 95℃ and 85℃. The anti scale rate reach to 100% when 3～5mg/L agent is added to the oily water.更多还原
