摘　　要：对难溶垢清洗剂 CQ- 1和 NS- 91 6等进行了室内评价和现场应用试验。在50℃条件下 ,CQ- 1对油田钙垢的清除效果优于进口产品 S4 6 6 ;在 70℃条件下 ,NS-91 6对油田钡垢的清除效果接近于 S4 6 6。The two non- dissolvable scale removers,CQ- 1 and NS- 91 6 ,are successfully ap- plied in the laboratory and in the field.At50℃ ,the effect of CQ- 1 to clean the calcium salts is better than that of the import product- S4 6 6 .At70℃ ,the effect of NS- 91 6 to clean the barium salts is close to S4 6 6 .Field test cleaning shows that CQ- 1 and NS- 91 6 on the non- dissolvable scale treatment in gathering systems are efficient,this technique has become a practical technique in the late stage of oil field development.
