Abstract: The paper describes the process of completing the chemical systems for acidising treatment near the wellbore for sandstone formations at Bach Ho and Rong fields of Vietsovpetro. The main components of the acid system (HF concentration and HCl/HF ratio) were improved to suit the modern technology widely applied in sandstone formations and enhance the ability to control secondary precipitation of undesirable products from Fe (III) and Al (III). On that basis, the authors also propose a number of further improvements for the acid system and relevant technology for the final stage of production. Keywords: Acidising, near-wellbore, prevent secondary precipitation. |
