摘　　要：大港北部油田注水水源为北部各污水站处理后水。通过对北大港、南大港和板桥3个区块的8种水样进行了研究,应用Stiff&Davis公式,根据CaCO3饱和指数和稳定指数预测得出北大港唐南回注水有一定的结垢倾向。配伍性试验结果表明,8种对应水样按不同体积比例混合,恒温密闭168h,均不产生沉淀;北大港及板桥的地层水和回注水经过滤处理后清澈透明,羊三木回注水经过滤处理后仍然浑浊,水的浊度大。The water processing in the north of Dagang Oilfield was used as source of injection water in north of Dagang Oilfield.Eight kinds of water was studied,Stiff & Davis expressions are applied.Tannan injection water has the tendency of CaCO3 scaling predicted by using the indexes SI and SAI determined.The experimental data on water compatibility show that deposite is not produced after heating in closed vessel at reservoir temperature for 168h.
