Summary
In acidizing treatment, lots of iron ions are formed in corrosive steel, ferric oxide, iron sulfides precipitation and other formation rock containing iron compounds dissolved in acid. The content of these iron ions will increase with the acidizing treatment continuing. with the furthering of acidizing treatment, the acid concentration decrease and the pH increase, do the Fe3+ will become Fe(OH)3 precipitation, while Fe2+ become FeS precipitation. Those precipitations will block the reservoir and result in new reservoir damage. Adding iron stabilizer into acid can chelate the iron ions and stabilize the Fe2+ effectively in high pH to prevent iron ions from forming precipitation to pollute the reservoir. DSS-303 iron ions stabilizer is non-toxic and good compatible with other acidizing finishing agent.
Application
DSS-303 iron ions stabilizer is mainly used in acidizing treatment to complex the Fe3+ to prevent the precipitation and improve the acidizing effect.
