Cationic Additive in Acid and Fracturing Fluid
The cationic additive in acid and fracturing fluid is the cationic quaternary ammonium surfactant polymer, and the appearance is colorless to pale yellow viscose liquid. It is water-soluble, non-toxic, has good hydrolytic stability, and keeps stable in wide pH. Freezing point:-2.8℃, specific weight:1.04g/cm3,resolve temperature: 280~300℃.
Clay minerals in the rock stratum will hydrate, and particles will expand and migrate during fracturing and acidification, which results in stratum plugging and degradation of oil recovery.
Cationic Additive in Acid and Fracturing Fluid inhibits clay’s expansion and particle migration, raising the effect of fracturing and acidification and prolonging the fracturing and acid-treating period. This Cationic additive in acid and fracturing cooperate with other agents well, is prepared conveniently and it’s non-toxic and tasteless.
|Appearance||Colorless to pale yellow viscose liquid|
|Solid content, %||40±1|
|Viscosity (25℃), cps||20,000~50,000|
In oil production, fracturing fluid is squeezed into the stratum, causing cracks and promoting seepage capacity. But Clay minerals in the rock stratum will hydrate and expand.
The particles will migrate during the process of fracturing and acidification. This cationic additive can inhibit the above phenomena and keep clay and minerals stable, which have expanded to prolong the fracturing and acid-treating
Cationic additives in Acid and Fracturing Fluid can be used as an expansion-prof agent in waterflood. Cationic additives in Acid and Fracturing Fluid can also be used as a ”cationic plugging agent” to react with ”actionic” in the oil displacement process to lower permeability. Make experiments before use to determine dosage and application.
Cationic additive in acid and fracturing fluid is applied in water-sensitive sandstone geology, in which the clay content is above 5%, concentration suggested is 0.05~0.5%, this product should be added when the Fracturing thickening agent expanded, then it takes effect after circulation.
Packing and storage:
Cationic additive in acid and fracturing fluid should be packed 200kg plastic drum or 1000kg/IBC drum.
Stored at room temperature, the storage period is one year.
