摘　　要：为了提高纤维复合防砂体的力学性能,采用在树脂涂覆砂中加入纳米SiO_2的方法对纤维复合体进行改性,通过超声波分散溶液共混法将纳米SiO_2(树脂质量分数的3%)均匀分散到水溶性酚醛树脂中,制备出纳米SiO_2改性树脂涂覆砂体,并加入纤维制备出纤维复合体。研究了不同防砂体的性能。结果表明,纳米SiO_2可以提高酚醛树脂涂覆防砂体的力学性能,几乎不影响纤维复合防砂体的渗透率,能使纤维复合体的强度提高;纤维可使树脂涂覆防砂体的渗透率提高11.13%。In order to improve mechanical properties of fiber complex sand control system, fiber complex was modified by introducing nanoparticles SiO2 into resin-coated sand. Nano-SiO2 modified resin-coated sand was made by dispersing nano-SiO2 （3% of resin mass fraction） into water soluble phenolic resin using ultrasonic dispersion solution blending method, and the fiber was added into nano-SiO~ modified resin-coated sand to obtain fiber complex. Properites of the different sand control systems were characterized. Experiment results showed that nano-SiO2 had good reinforcing effect on the mechanical properties of the resin coated sand control system and had little effect on the permeability of the fiber complex sand control system, the compressive strength of the fiber complex modified by nano-SiO2 was improved by 26.12% ; on the other hand, fiber could improve the permeability of the resin coated sand control system by 11.13%.
