Abstract: The Longmaxi Formation shale reservoir in southeastern Chongqing exhibits complex geological characteristics, including low porosity and permeability, high temperature, high salinity, and well-developed natural fractures. Slickwater fracturing fluids play a crucial role in its reservoir stimulation. This paper reviews recent advances in the performance research of slickwater fracturing fluids applicable to this reservoir, covering drag reducer systems, mechanisms of action, optimization for temperature and salt resistance, field applications, and future directions for technological innovation. Current challenges for slickwater fracturing fluids include high-temperature degradation, poor salt compatibility, and balancing proppant carrying and flowback. Future efforts should focus on breakthroughs in molecular structure design, development of environmentally friendly systems, intelligent regulation, and efficient proppant-carrying technologies. These advancements will facilitate the construction of high-performance fracturing fluid systems, providing critical support for the efficient development of deep shale gas resources.
