The primary composite proppant particles

Proppants currently used mainly Proppant quartz sand, bauxite and ceramic sand and resin-coated composite particles. Due to the low cost quartz sand, while low density easy pumping, is widely used, but quartz sand strong low end, the ball is poor, reducing fracture conductivity, does not apply to closed high pressure deep well. Resin composite particles coated quartz sand, sphericity improved corrosion resistance strong, conductivity is also good, but the products remain short-term, the cost is too high, the cost-oriented promotion today is not easy, and the use of bauxite ceramic proppant ceramic technology, high density, good sphericity, corrosion, high temperature, high pressure, while the costs can be better controlled, and therefore more and more widely used in oil and gas fields. Practice has proved that ceramic proppant the use of ceramic proppant fracturing of oil wells can increase production by 30-50%, but also to extend the service life of oil and gas wells, a key material in the oil and gas wells in low permeability oil and gas extraction, construction, not only to increase oil and gas production, and can extend the service life of oil and gas wells.
