Safe 20-50% Polydadmac Water Treatment As Cationic Modifier For Oildfields

Product description:
​Polydiallyldimethylammonium chloride (PolyDADMAC) is a cationic quaternary ammonium salt type polymer surfactant, and its appearance is colorless to light yellow viscous liquid. Soluble in water, safe, non-toxic, good hydrolysis stability, strong adaptability to pH changes. The specific gravity is about 1.02g / cm3, and the decomposition temperature is about 280-300 ° C. This product absorbs the clay mineral surface in the sandstone oil layer through physical and chemical action. The absorption force is strong, the clay mineral is stable for a long time, it is resistant to erosion and the amount is small; resistant to acid, alkali and salt; insoluble in crude oil and hydrocarbons, resistant to Strong oil-washing ability, no wetting inversion.

Application:

PolyDADMAC is used in oilfields, as oilfields are mostly developed for water injection, and clay minerals in sandstone reservoirs expand and migrate in contact with water, causing serious sand production. Sand production from oil and water wells seriously affects normal production in the oil fields. Therefore, sand control and suppression of sand production from oil and water wells are necessary. PolyDADMAC is used as Cationic modifier can effectively prevent clay swelling and microparticle migration, and eliminate or reduce damage to formation permeability to achieve the effects of increasing sand production and injection. PolyDADMAC can also be used for modification of oilfield working fluids such as thickened well killing fluid, well washing fluid, fracturing fluid, and acidifying fluid.
