Study on Silicon Scale-Forming in ASP Flooding System

Abstract:

Aiming at the production wells’ problem of stuck pump, blocking, pipeline corrosion and scaling in ASP flooding test area in Daqing oilfield Xingbei block, based on the actual situation the study system was defined, on the basis of laboratory experiment to simulate silica scale forming, and the forming process was observed, the silicon scale-forming regular after the formation of alkali corrosion was studied. The results showed that in the complex condition of ASP flooding system, silica scale forming was affected by variety of factors, the process was that monosilicic acid gets together to poly silicic acid, and then condensation polymerization and dehydration generate gel. In the process of polymerization, the silicic acid can polymerize alone or adhere to another pellet molecule, polymerization and dehydration generate to mixed scale.
