Ultralow-density ceramisite sand proppant and preparation method thereof
The invention discloses an ultralow-density ceramisite sand proppant and a preparation method thereof. The ultralow-density ceramisite sand proppant is prepared from the following raw materials in percentage by weight: 15-20% of purple clay, 10-15% of silica and 65-75% of raw aluminum ores. The preparation method comprises the following steps: crushing the required raw materials at first, then performing blending and grinding, and putting obtained fine powder into a granulator for granulation; and screening obtained raw granules after granulation, then calcining in a rotary kiln, cooling, and finally screening again to obtain a product. The ceramisite sand proppant prepared by the method disclosed by the invention has the advantages of ultralow volume density, relatively low apparent density, relatively high crushing resistance and good surface finish quality. By using the ultralow-density ceramisite sand proppant disclosed by the invention, the exploitation cost of an oil field can be reduced, and the yield of the oil field can be increased.
