Inhibitor of CaCO3-HCl reaction for Long-distance Acidizing (ILA)

Inhibitor of CaCO3-HCl reaction for Long-distance Acidizing (ILA)

ILA is invented and designed for remote acidizing process, especially for high temperature formation, for high temperature over 90, the slow release of HCl effectively reduces the CaCO3-HCl reaction speed.

Test result under the condition of 90 ℃, put 8g limestone into 200g 20%HCl, the consuming time ( 4g, 50% as follows
