Quaternary ammonium salts have various functions in oilfield water treatment. Some of the main functions are as follows:

• Dispersant: Quaternary ammonium salts can be used as an excellent dispersant to disperse and stabilize solid particles and colloidal substances in oilfield water. During the process of oilfield water injection, there may be suspended particles or colloidal substances in the water, which may reduce the quality of water and affect the effectiveness of water injection. The dispersion effect of quaternary ammonium salts can disperse these substances into water, thereby improving the quality of water.
• Fungicides: Quaternary ammonium salts have certain bactericidal and antibacterial effects, which can effectively inhibit the growth of microorganisms in water. In oilfield water injection, the water source is often groundwater or other sources that may contain microorganisms. The growth of microorganisms may lead to deterioration of water quality and even cause corrosion to oilfield equipment and pipelines. The bactericidal effect of quaternary ammonium salts can reduce the proliferation of microorganisms and maintain the cleanliness and hygiene of water.
• Scale inhibitor: Oilfield water may contain various salts and hardness substances, which can easily deposit on the surface of pipelines and equipment, forming a scale layer. Quaternary ammonium salts, as a scale inhibitor, can react with these salts and hardness substances to form a protective film on the surface of pipelines and equipment, preventing the formation of scale layers and maintaining the normal operation of equipment.
• Emulsifier: In oilfield production, water and oil are often mixed to form a lotion system. Quaternary ammonium salts can serve as emulsifiers to regulate the interfacial properties of water and oil, promoting their mixing and stability. The use of emulsifiers can improve the oil-water separation efficiency in oilfield production processes and increase oil well productivity.
