The interest in the application of nanofluid reducing injection pressure has been increasing especially for tight reservoirs. In this work, a new type hydrophobic carbon was prepared and pressure-reducing performance investigated. results particle size distribution, zeta potential, transmission electron microscopy image showed that dispersion uniform stable. addition, excellent antitemperature antisalinity property. contact angle oil-wet glass slide can range from 45 to 89° after it adsorbs nanoparticles (HCNPs). atomic force microscope tests core surface roughness reduced about 16.67%. flooding rate 0.15 wt % HCNP reach 17.00%. HCNPs show good have broad prospect oil field development.
