Drag reducer--Cationic Acid Thickener

Oil and water well acid treatment (acidification) is to inject one or several kinds of acid liquid or acidic mixture through the wellbore into the formation, and use the dissolution and etching effect of the acid on the rock cementing materials or the plugging materials in the formation voids and cracks (such as iron oxide, ferrous sulfide, clay), to restore or increase the permeability of the formation voids and cracks, so as to make a kind of process measure to increase the output of oil and gas wells or to increase the injection of water injection wells. Cationic Acid Thickener is mainly suitable for low-permeability carbonate reservoirs. In the process of the development of acidification technology, the application of the new type of Cationic acid thickener focuses on reducing the corrosion of the acid on the pipeline and equipment, controlling the reaction rate of the acid-rock, improving the acidification effect, preventing formation pollution and reducing the construction cost. The gelling cationic acid thickener developed by our company is a polymer of high-molecular emulsions, with strong cationic charges and a higher relative molecular mass. In the acid, the macromolecular chain extends, and has excellent thickening and hydrophilic properties; its C--C bond main chain is more resistant to temperature, acid and high pressure.
