| Abstract: | The oilfield produced water at Zaoda water-treating station in Dagang Oil Fieds is of CaCl_2 type, highly mineralized(20000mg/l) and contains dissolved CO_2 and scaling in pipelines has been a troublesome problem at the station. A phosphonic acid, HEDP, is selected out for scale inhibition of the produced water through laboratory scaling and corrosion tests and polarization curve constrution. In the field test at Zaoda station HEDP in use level of 5mg/l introduced continuously led to decreasing Ca~(2+) loss in pipelines from several hundreds to no more than 10ppm, that is, from some 20% to less than 0.45%. |
