The fracturing fluid plays a vital role in hydraulic fracturing and its properties will directly influence on the fracturing operations and stimulation effect. The advantages，disadvantages and application of different fracturing fluids were analyzed. The rheological properties of water-based fracturing fluid at high pressure were described and the method of improving the rheological properties of water-based fracturing fluid by using nanomaterials as well as non-oxide gel-breaking were pointed out，providing a novel approach to improve the work efficiency and recycling of water-based fracturing fluid.
