VDA/acid system for matrix acid stimulation |
摘要 |
A method of preventing phase separation of a viscoelastic surfactant fluid or diverting agent due to ferric ions during matrix acidizing of an oil well which involves the injection of both citric acid and acetic acid which prevents the separation of the viscoelastic diverting agent/acid with ferric ions which avoids damage to well productivity and/or injectivity.
