Research on the suspended solids in the reinjection water of Daqing Oilfield

The concentration and size of suspended solids(SS)beyond the criteria have seriously affected the quality of oilfield reninjection water.To solve this problem,we chose the reninjection water of Daqing Oilfield as test subjects,precisely analysised the compositions of SS.We also conducted a study about the factors that impact on SS,such as flocculating agent,oil and bacteria.It turned out that these factors contribute to the increased concentration of SS.
