摘要
通过准静态和循环条件下的溶垢试验、岩心伤害和解堵试验、腐蚀试验对国产钡垢清除剂ＣＱ－２和ＮＳ－９１６、英国ＡｋＺＯ公司的Ｓ４６６进行了比较评价，并与文献报导的国产清垢剂ＳＬＰ－１作了比较。ＣＱ－２、ＮＳ－９１６、Ｓ４６６在体积浓度为２５％－５０％时，在５０－７０℃下２４－４８小时的溶钡垢量均在９．９－１１．２ｇ／ｌ范围内。
Three scale-removers for barium/stronium salts precipitations in reservoirs(home made CQ-1 and NS-9l6 and Akzo'S466) are studied both in vessel and in core tests and compared with another home made chemical,SLP-l.on the basis of data published.The BaSO_4 scale dissolving ability of these chemicals of volume concentration 25%-50% is in the range of 9.9-11.2g/l in 24-48 hrs at 50-70℃.
