Product Introduction:

In the process of oil-water well acidizing operation, acid liquid quickly dissolves the iron in the pipeline and equipment and the iron mineral in the corroded formation, to form a large amount of free Fe2+ and Fe3+, while these frric ions kept in the solution is a potential problem giving rise 10 formation damage. When pH value of the solution is bigger than 2. it is easy to form Fe (OH)3 deposit combined with OH- in the solution, to block the formation and pipeline. and affect the oil- water well operating production. At the same time, in the process of acidzing operation, though a great deal of acid liquid neertby the well belt has not yet been used up. the residual acid zone (PH value is 5) is formed at the front edge of reaction, even if the residual acid is retumed timely after operation, the remain of residual acid stil exists at the front edge, as a potental factor causing Fe (OH)3 deposit. CH frric ion stabilizer is namely a kind of amino carboxyl acid chelating agent developed by our company aiming at the secondary sedimentation of ferric ion in acidzing operation, especialy aplicable to deep well ac dification. Tests on more than 100 wells on the sites of Jianghan, Dagang. North China, Shengl, Liache and other work units have proved that CH frric ion  stabilizer is a good chemical additive for cntolling Fe3+ sedimentation, and preventng formation damage.

Technical Indicators:



The frrie ion sabilizer is mainly aplied to oilield oil-water well acidiring operation, and this aditive is also used in the pre-acid in fracturing operation.

Method of Application:

(1) It is mainly applicable to oil-gas well formation acid fracturing process and water injection system, 8as well as oil transportation pipeline acid washing operation:

(2) It serves as various acidizing adtives for hydrochloric acid, and mud acid, as well as blending of hydrocloic acid with phosphoric acid;

(3) General adding amount is contold at 3~5%;


1. Skin contact shall be avoided as much as possible. taking orally is strictly prohibited, and it shall be immediately fushed if  alling into eyes. Go to doctors for diagnosis and treatment when necesary.
