| Abstract: | The produced water of several drive blocks in Daqing oilfield and Nanyang oilfield were digested by high-pressure digestion pot,and the full ions were analyzed.The contents of Na,K,Ca,Mg,Al,Ba,Sr,Mn,Si in water were determined by ICP-AES.The recoveriss were 95.00%—106.00% and the relative standard deviations were less than 2.15%.The contents of Cl-,SO2-4 were determined by ion chromatography in produced water of each drive block.The recoveries were 96.83%—99.28% and the relative standard deviations were less than 2.28%.At the same time,the contents of HCO-3,CO2-3 were determined by chemical methods to all produced water.Salinity of produced water was so high in Daqing oilfield and Nanyang oilfield which could directly affect oil recovery.Ba,Sr and Si,etc were found in produced water of the drive block also.The anions and cations in oilfield produced water combine with each other,causing the wall scaling.The contents of Cl-,SO2-4 in two oilfield produced water were very high,and they will lead to serious corrosion in oil underground pipeline. |
