Solid Acid
Overview

Routine acidizing/acid fracturing operation has high requirements on acid storage and transportation. The reaction speed of conventional acid is fast and difficult to achieve deep penetration, resulting in excessive reaction and waste of the acid. Conventional acid cannot remove blockage that caused by sulfate and other hardly soluble matters and it is difficult to conduct acidizing in high temperature reservoirs.

1. All products are solid particles, which can be pumped directly from the blender or per-mixed into liquid.
2. The product does not contain oxidant, benzene, phenol, ether, aldehyde and organic chlorine. It is non-toxic and harmless. It does not need treatment for flowback liquid. More than 85% can realize self degradation.
1. Acidizing / acid fracturing fluid of carbonate reservoir.
2. Sandstone acid proppant fracturing (proppant and solid acid are mixed in advance)
3. Water well plugging removal and injection increase, oil well plugging removal and production increase system (sandstone reservoir).
4. Break and degrade the residual polymer injected.
