    Abstract
  • A modified nano SiO2 with core-shell structure was prepared through sol-gel method, using tetraethoxysilane (TEOS) as the source of Si, ammonia water as catalyst, water as accelerant, and phenylethylamine propyl trimethoxy silane as surface modifier. The molecular structure of the SiO2 was characterized through FT-IR, PSDA and TEM, and the modified SiO2 was compared with nonmodified SiO2 as to the particle size distribution and microscopic morphology in the filtrate of drilling fluid. Several nano SiO2 additives were evaluated by testing their capabilities to plug nano fractures on a simulator, and the mechanism of nano-dispersion of these SiO2 additives in drilling fluids was discussed. Compared to non-modified SiO2, the modified SiO2 shows nano-dispersion in drilling fluids, and can effectively plug the nano-sized fractures. At a concentration of 3.0%, 99.21%of the nano-sized fractures on the simulator were plugged.
