Study On Reinjection Technology of Sewage With SO₄²⁺ in Oilfield

ZHANG Dong, WU Wenxiang

Abstract

SO₄^2- rich in reinjection sewage combined with Ca²⁺, Mg²⁺in formation water to form precipitate which results clogging in the formation pore. Ion exchange method was chosen to remove SO₄^2- in reinjection sewage and the anion exchange resin with OH^- is selected as the exchange medium. It is necessary to evaluate alkali sensitivity of the formation rock due to the reinjection of sewage containing excess OH^-. The results indicate that ion exchange method can remove more than 90% of the SO₄²⁺ and the rate of formation damage is negligible when the pH below the critical of 9.8.

Key words: SO₄^2-; Ion exchange method; Scaling; Alkali sensitivity

Keywords

SO42+; Ion exchange method; Scaling; Alkali sensitivity
