Oil fracturing proppant in the field to guide the country into the international market

Currently used mainly  Ceramic proppant   bauxite ceramic sand and resin-coated composite particles. Since quartz sand, low cost, low density easy while pumping have been widely used, but the low end strong quartz sand, the ball is poor, reducing fracture conductivity, does not apply to closed high pressure deep well. Composite resin coated quartz sand particles sphericity has improved corrosion resistance strong, conductivity is also good, but the product retention period is short, the cost is too high, the cost of promoting the supremacy of today is not easy, and the use of bauxite ceramic craft ceramic proppant, high density, sphericity, corrosion resistance, high temperature, high pressure, while costs can be better controlled, thus being more and more widely used in oil and gas fields.
    Ceramic sand has a high fracture strength, mainly used for oil well supported in order to increase oil and gas production, an environmentally friendly product. This item is the use of high-quality bauxite, coal and other raw materials, sintered ceramics, natural silica sand, glass beads, metal balls, low intensity proppant substitute for oil and gas production with good results.  Proppant  have sufficient compressive strength and wear resistance, can withstand the strong injection pressure and friction, and effectively support the artificial cracks. Proppant particles of relatively lower density, pumped downhole easy.
    Oil and gas deep mining, the high closure pressure low permeability deposits by fracturing treatment, the rock cracked hydrocarbon, oil and gas from the cracks formed in the channel pooling out. Alumina support material with a solution into the formation along with the high-pressure filling fissures in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that gas flow, increase production. Also extend the service life of oil and gas wells.
    Deep mining in the oil and gas, the high closure pressure low permeability deposits by fracturing treatment, the rock cracked hydrocarbon, oil and gas from the cracks in the channel formed together out of the fluid injected into the rock grass at this time need to exceed the formation fracture intensity of pressure on the rock around the wellbore cracks, forming a channel with high flow capacity, in order to maintain open after fracturing the formation of cracks, oil products can smoothly pass. Petroleum proppant into the formation along with high-pressure solution filled in the cracks in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that gas flow, increase production.
    Practice has proved that using ceramic proppant fracturing of oil wells can increase production by 30-50%, but also to extend the service life of oil and gas wells, oil and natural gas wells in low permeability oil and gas exploration, construction of key materials, not only can increase oil and gas production, And more extended service life of oil and gas wells. Ceramic proppant is the main raw material bauxite,  fracturing proppant  its good ability to support, and gradually replace the conventional proppant sand, into the U.S. market.
