Proppants is widely used

Proppants currently used mainly in quartz sand, resin coated ceramic support agents and 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 coated sand proppant, the sphericity improved corrosion resistance strong, conductivity is also good, but the products remain short-term, the cost is too high, the cost-oriented promotion is not easy today, while the use of bauxite ceramic proppants ceramic technology, high density, good sphericity, corrosion resistance, high temperature, high pressure, while the costs can be better controlled, and therefore more and more widely used in oil and gas fields.
