Summary
OBC- CI is an organic cationic adsorption film type corrosion inhibitor compounded according to the theory of synergistic action of corrosion inhibitors.
Good compatibility with clay stabilizers and other treatment agents, which can formulate low turbidity completion fluids and reduce the damage to the formation.
Effectively reducing the corrosion of downhole tools by dissolved oxygen, carbon dioxide and hydrogen sulfide.
Good bactericidal effect on sulfate-reducing bacteria (SRB), saprophytic bacteria (TGB), and Fe bacteria (FB).
Good corrosion inhibition effect in wide pH range (3-12).
