A series of polystyrene/carbon black composite microspheres as oil fracturing low-density proppant have been successfully synthesized via one-step technique of suspension polymerization. The apparent density of the microspheres was around 1.025–1.077 g/cm3 which favored the hydraulic transportation in oil drilling; the thermal stability of the proppants was improved remarkably. The oil permeation performance of low density proppants with optimum addition of CB was superior to commercial available products. Hence, PS/CB composite microspheres serving as the newly developed low-cost and low-density proppant would have a good prospect in the field of oil exploitation.
