Abstract:Aiming at the problem
of single and poor adaptability of Bai-823
plugging removal system, an authigenic mud acid system using methyl
formate, ammonium chloride, and ammonium fluoride as raw materials
is proposed, which can adapt to the temperature of 60–80 °C
of the target reservoir and sandstone lithology. The acid-generating
capacity of the authigenic acid system at different temperatures was
evaluated. The results showed that the H

concentration
remained at 3.35 mol/L after 180 min … Show more
