Material composition of ceramic proppant

Currently used mainly quartz sand maide proppants for hydraulic fracturing , bauxite sand and resin-coated ceramic composite particles. Due to the low cost of quartz sand , while lower density easy to pump , has been widely used , but quartz sand strong low end , the ball is poor, reducing the fracture conductivity , does not apply to high pressure deep well closed . Composite resin coated quartz sand particles , sphericity improved corrosion resistance strong, conductivity is also good , but the products remain short- term , the cost is too high, the cost of the promotion of the supremacy of today is not easy , and the use of bauxite ceramic craft maide ceramic proppants , high density, good sphericity , corrosion resistance , high temperature, high pressure, while costs can be better controlled , and therefore more widely used in oil and gas fields being . Practice has proved that the use of ceramic proppant fracturing oil wells can increase production by 30-50% , but also to extend the service life of oil and gas wells , is the key material oil, gas wells in low permeability oil and gas exploration, construction , not only to increase oil and gas production , and more to extend the service life of oil and gas wells .
The main raw materials of ceramic proppant is bauxite, while China is a country rich bauxite , bauxite distribution is highly concentrated, Shanxi, Guizhou, Henan and Guangxi in four provinces (regions ) of the total national reserves reserves Total of 90.9% ( 41.6% of Shanxi , Guizhou, 17.1% , 16.7%, Henan , Guangxi, 15.5% ) , and the remaining 15 provinces, autonomous regions and municipalities have bauxite reserves total only 9.1 % of the country 's total reserves . Chinese ceramic proppant manufactured good support for its ability to gradually replace conventional proppant sand, into the U.S. market . So far, the Chinese -made ceramic proppant ceramic proppant has occupied the entire North American market share of 13% , the average annual business volume of $ 3 billion
