High-strength low-density ceramsite proppant and preparation method thereof
The invention discloses a high-strength low-density ceramsite proppant and a preparation method thereof. The ceramsite proppant is prepared from, by mass, 47%-60% of low-grade bauxite, 25%-40% of chinastone, 5%-15% of ceramsite proppant production waste, 0.3%-0.5% of industrial boric acid, 3%-10% of magnesian clay and 2.5%-3.6% of silica fume. The price of raw materials adopted by the ceramsite proppant is generally low, so that the production cost is greatly reduced; meanwhile, the volume density of the obtained ceramsite proppant is 1.42 g/cm<3> to 1.50 g/cm<3>, the apparent density is 2.61g/cm<3> to 2.68 g/cm<3>, the breakage rate is lower than 5 percent under the closing pressure of 52Mpa, the fracturing cost is reduced, and the yield of an oil and gas field is increased.
本发明公开了一种高强度低密度陶粒支撑剂及其制备方法。所述陶粒支撑剂包括以下质量分数的组分：低品位铝矾土47‑60％，瓷石25‑40％，陶粒支撑剂生产废品5‑15％，工业硼酸0.3‑0.5％，镁质粘土3‑10％，硅灰2.5‑3.6％。所述陶粒支撑剂采用的原材料价格普遍较低，大大降低了生产成本；同时得到的陶粒支撑剂体积密度为1.42‑1.50g/cm,视密度为2.61‑2.68g/cm,闭合压力为52Mpa下破碎率低于5％，有利于降低压裂成本，还有利于油气田增产。
