Low-density high-strength micro-nano ceramic proppant and preparation method thereof
The invention discloses a low-density high-strength micro-nano ceramic proppant and a preparation method thereof, and belongs to the technical field of oil exploitation. The bulk density of the proppant is 1.0-1.5 g/cm < 3 >, the true density of the proppant is 2.4-2.8 g/cm < 3 >, and the compressive strength of the proppant is 52-103 MPa. The preparation method comprises the following steps: mixing powder of the drilling cuttings, the bauxite and the potassium feldspar, adding water, and uniformly stirring to form slurry; grinding the slurry, adding a binder and a dispersant, uniformly stirring, and aging; the aged product is placed in a centrifugal spray drying tower to be formed, and a proppant blank is obtained; and sintering the green body to obtain the product. The micro-nano ceramic proppant is prepared by taking the drilling cuttings as raw materials, so that the problems of stacking and treating the drilling cuttings are solved, and the recycling of the drilling cuttings is realized; meanwhile, the prepared micro-nano ceramic proppant has ultra-low density and high strength.
本发明公开了一种低密度高强度微纳米陶瓷支撑剂及其制备方法，属于石油开采技术领域。所述支撑剂的堆积密度为1.0‑1.5g/cm3，真密度为2.4‑2.8g/cm3，抗压强度为52‑103MPa。其制备方法为：将钻井岩屑、铝矾土和钾长石的粉料混合，加水搅拌均匀，形成浆料；将所述浆料研磨后加入粘结剂和分散剂，搅拌均匀后老化；将老化后的产物置于离心喷雾干燥塔成型，得到支撑剂坯体；将所述坯体进行烧结，即得。本发明通过以钻井岩屑为原料，制备微纳米陶瓷支撑剂，解决了钻井岩屑堆放和处理问题，实现了钻井岩屑的回收再利用；同时，所制备的微纳米陶瓷支撑剂具有超低密度和高强度。
