| The reasons that caused the equipment corrosion problems in the water injection system in Jilin Hong-gang Oil production plant have been analyzed in detail.Based on the analysis of the water quality of the injected water,oil field produced gas and dissolved gas,bacteria growth condition and the component of the corrosion deposits,as well as the comprehensive consideration of the technical situation on the spot,it is finally affirmed that the main reason which caused the equipment corrosion was due to the bacteria corrosion.It was a result of a long term sulfate reducing bacteria(SRB)breeding.Through the selection of chemicals and filed experiments,it is proved that Bactericide,TS-780 is good not only for killing bacteria but also for inhabiting corrosion.It can solve the bacteria corrosion problem efficiently in the water injection system in oil fields. |
