http://geology.com压裂砂是一种高纯度的石英砂,有着超强的抗压性和极高的磨圆度。这种物质被人为地压碎后,主要用于石油工业领域。特别是在水力压裂的应用,即用高压水泵将压裂液注入油气储层内,将储层压碎以获得油气资源,压裂砂是一种不可或缺的物质。大部分石英砂均来自于高纯度的石英砂岩,但也有部分石英砂的替代品,如陶粒和金属颗粒,前者来源于铝土矿, Fracturing sand is a high-purity quartz sand with superior resistance to compression and very high roundness. This material is artificially crushed, mainly for the oil industry. Especially in the application of hydraulic fracturing, that is, using high pressure water pump to inject fracturing fluid into the reservoir and crushing the reservoir to obtain oil and gas resources, fracturing sand is an indispensable material. Most of the quartz sand comes from high-purity quartz sandstone, but there are also some quartz sand substitutes, such as ceramsite and metal particles, the former comes from bauxite,
