| description | At present, hydrophobic nanoparticles are used in oil exploitation as an effective decompression and injection augment means, but the decompression and injection augment mechanism of the hydrophobic nanoparticles is not very clear. In order to further study the function of the hydrophobic nanoparticles in decompression and injection augment, the invention synthesizing the hydrophobic nanoparticles with high monodispersity by using an 'in-situ modification' method in hope of finding out the relationships between decompression and injection augment and the performance of the nantoparticles such as particle size, wettability and grafting rate. The obtained sample is treated by analyzing means such as atomic force microscope, infrared absorption spectrum, contact angle measurement, thermogravimetric analysis, dynamic light scattering device (for measuring zeta electric level) so as to characterize the product. This indicates the synthesis method is feasible. |
