Research and Design on Production-Education Integration of Clean Fracturing Oil Displacement Integrated Working Fluid

This study proposes a comprehensive experimental design to prepare a clean and low damage viscoelastic surfactant (VES) fracturing fluid using hexadecyltrimethylammonium chloride. The fracturing fluid integrates fracturing and oil displacement functions. This experiment addresses the urgent need for environmentally friendly working fluids in the petroleum industry, which can minimize formation damage while improving oil extraction efficiency. Through molecular design and performance evaluation, including temperature resistance, shear stability, sand carrying capacity, and gel breaking performance, researchers from oil and gas field enterprises and students from petroleum universities can systematically explore the preparation and application mechanisms of integrated working fluids. This educational module reflects profound industry education integration by transforming real industrial challenges, such as permeability damage caused by traditional fracturing fluids, into rigorous academic research opportunities. Researchers and university students in oil and gas field enterprises acquire comprehensive abilities, including literature review, experimental design, data analysis, and scientific reporting, while internalizing the green chemistry principles necessary for sustainable oil extraction. The experiment was conducted in a collaborative group format, cultivating teamwork and independent problem-solving skills, directly linking theoretical knowledge with on-site applications. This method significantly enhances students’ professional preparation and innovation abilities, enabling them to meet real-world petroleum engineering needs while promoting the industry's transition to clean production practices.
