High-strength low-density ceramsite proppant and preparation method thereof
The invention provides a high-strength low-density ceramsite proppant and a preparation method thereof. The high-strength low-density ceramsite proppant is prepared from the following raw materials in percentage by mass: 60%-65% of silica sand, 18%-23% of forsterite, 10%-15% of red iron ore and 1%-5% of bentonite. Preferably, the casting sand comprises the following raw materials in percentage by mass: 60% of silica sand, 22% of forsterite, 15% of red iron ore and 3% of bentonite. The preparation method of the high-strength low-density ceramsite proppant comprises the following steps: S1, grinding; S2, mixing; S3, granulating; S4, drying and screening; the rich and cheap silica is fully utilized, waste is turned into wealth, the resource utilization range is expanded, the prepared novel ceramsite proppant has the advantages of being low in breakage rate, low in density, high in strength, low in acid solubility and good in roundness and sphericity, the performance requirement of the proppant for hydraulic fracturing can be met, and the novel ceramsite proppant is suitable for being used for hydraulic fracturing. The bauxite ceramsite proppant is effectively replaced, meanwhile, the raw material cost and the fuel consumption are greatly reduced, and energy conservation and environmental protection are achieved.
本发明提供了一种高强低密度陶粒支撑剂及其制备方法，所述高强低密度陶粒支撑剂包含以质量百分比计的如下原料：硅砂60％～65％、镁橄榄石18％～23％、红铁矿石10％～15％、膨润土1％～5％；优选包含以质量百分比计的如下原料：硅砂60％、镁橄榄石22％、红铁矿石15％、膨润土3％。所述高强低密度陶粒支撑剂的制备方法，包括以下步骤：S1磨粉、S2混炼、S3造粒、S4干燥筛分、S5烧成。本发明充分利用丰富廉价的硅石，变废为宝，不仅实现了扩大资源利用范围，且制备的新型陶粒支撑剂具有低破碎率、低密度、高强度、低酸溶解度、良好的圆度和球度的特点，可以满足水力压裂用支撑剂的性能要求，实现对铝矾土陶粒支撑剂的有效替代，同时大幅降低了原材料成本和燃料使用量，节能环保。
