| Overview
Acidified with chelating agents, can effectively complex free iron ions, so that it always exists in the form of complex ions and return to the ground with flowback acid, can effectively prevent the generation of secondary sedimentation, increased acidification effect. Acidified with aminoxatyl complexing agent is a chelating agent containing ammonia and complexing ability of the two carboxyl oxygen atoms with strong, with Fe3 + to form a stable chelate to prevent precipitation of iron in the formation and reduce silt slag generation, improve yield increase acidification job.

Scope
As well temperature and acidified with conventional fracturing and acidizing within 90 ℃, to prevent iron precipitation in the formation to reduce sludge formation and reduce the formation of secondary damage.
Recommended dosage
This product is recommended for the normal concentration of 1.2% to 2.0%.
Use
By ferric ion stabilizer designed to determine the amount of the other additives together with the acid is added to hydrochloric acid, and then diluted with water to the design of acid concentration, even immediately after the pump.
Product packaging
Products with a plastic barrel, net weight 250kg (according to user requirements).
Product storage
The product must be tightened during storage lids in a cool ventilated place, the storage period of 1 year. At low temperatures, or stored for too long the barrel may have crystallized, generally do not reduce the efficacy. Stir well, does not affect the results. |
