As oilfield exploitation enters the middle and late stages, the water content of oil wells soars, the difficulty of oil-water separation in produced fluids increases dramatically, and the efficiency of traditional demulsifiers decreases, affecting crude oil production and quality, and increasing gathering and transportation costs. Aixiang Industry and Trade's new demulsifier with cationic monomer methacryloyloxyethyl trimethyl ammonium chloride (DMC) as the core ingredient has appeared to reverse the situation.
After being injected into the wellhead, the demulsifier quickly diffuses to the oil-water interface, and with its unique chemical structure, it reduces the oil-water interfacial tension, accelerates the aggregation and floating of emulsified oil droplets, and achieves rapid oil-water separation. In the three-phase separator of the joint station, the originally emulsified viscous produced fluid quickly stratifies, the water content of crude oil drops to below 0.5%, and the water quality meets the standard for reinjection into the formation, reducing water resource waste and formation damage.
Oilfield engineers praised: "This demulsifier has strong pertinence and wide adaptability, and its performance is stable under complex reservoir conditions. While improving crude oil recovery, it ensures the efficiency and smoothness of the entire production and transportation system, laying a solid foundation for stable and increased production in oilfields."
