Abstract: Proppant hydrophobic surface treatment can make proppant reduce oil field produced water while support fracture, control sand. The hydrophobic surface treatment method in terms of both ordinary hydrophobic and superhydrophobic was summed up. The ordinary hydrophobic surface preparation method is divided into three aspects of surface active agent, organic silicon material, fluorinecontaining material; the superhydrophobic surface preparation method is divided into the solgel method, electrospinning method, template method, layers of selfassembly and etching method. Those preparation methods was compared, combined with the situation that water suppression proppant was applied to the field, proposed the hydrophobic surface preparation method was applied to the proppant. Using surfactant hydrophobic modification experiments on quartz surface, the effect of the cationic surfactant CTAB is best, contact angle on the surface of the quartz from 13.7° increases to 73.2°, the Surface tension is 48.88 mN/m, the adsorption capacity of 0.292 mg/g. Finally, it is conceived that hydrophobic surface modification methods was applied to other oilfield areas.
