【Abstract】 A new profile control agent,fluosilicic acid water glass,was studied in this paper.Its performance was compared with that of bydrochloric acid water glass system.The results showed that the fluorsilicic acid water glass system is of the advantages such as low cost,good profile control and sand consoidation ability.The dual effects of profile control and sand consolidation can be observed when it is used in water injection wells.更多还原
