High Efficient Scale Inhibitor for Barium /Strontium Sulfate Scale in Oilfield

During the oilfield development, the scaling is quite complicated and has great harm to production. For solving the problem of scaling in oilfield production system, especially for prevention and control of barium/ strontium sulfate scale, evaluation tests on compound scale inhibitor were carried out. A high efficient compound inhibitor for barium/strontium sulfate scale was prepared and its indoor anti-scaling rate was over 90%, which can provide technical support for the safety in oilfield production.
