Acidizing diverting agent
Acid diversion agents are formulated from a blend of long-chain surfactants and other synergists. These agents have a low initial viscosity in the acid solution; however, once injected into the formation, as the acid-rock reaction proceeds, the acid concentration decreases, and the concentration of inorganic salts such as calcium chloride increases.

Product Description
Acid diversion agents are formulated from a blend of long-chain surfactants and other synergists. These agents have a low initial viscosity in the acid solution; however, once injected into the formation, as the acid-rock reaction proceeds, the acid concentration decreases, and the concentration of inorganic salts such as calcium chloride increases. The acid redirection agent gradually transforms from spherical micelles to worm-like micelles, causing the viscosity of the acid solution to increase rapidly. This effectively seals off high-permeability zones, redirecting the acid solution to low-permeability zones and thereby achieving uniform acidization. Once the self-redirecting acid comes into contact with oil, the micelles break down, making it easy to flush out.
Product Features
1. Formulated from a blend of long-chain surfactants and other synergists.
2. Rapidly increases the viscosity of the acid solution, effectively sealing off high-permeability zones and redirecting the acid solution to low-permeability zones, thereby achieving uniform acidization.
3. The self-redirecting acid breaks down upon contact with oil, making it easy to flush out.
4. Compatible with other additives.
Application
Used in oilfield acidizing operations, it rapidly increases the viscosity of the acid solution, effectively sealing high-permeability zones and redirecting the acid solution to low-permeability zones, thereby achieving uniform acidizing.
