<p>Disclosed is a petroleum fracturing proppant prepared from waste ceramics by using waste ceramics, potassium feldspar powder, manganese ore powder and bauxite powder as raw materials. The present invention uses low-cost waste ceramics as raw material, and in the preparation process,Αl2O3 in the waste ceramics is prepared into mullite, and the surplus SiO2 in the raw material is converted into a low apparent-density mineral such as tridymite, thereby reducing the apparent density of the product. Results show that the volume density of the petroleum fracturing proppant prepared from waste ceramics of the present invention is less than or equal to 1.60 g/cm3, the apparent density is less than or equal to 2.70 g/cm3, and the crushing rate is less than or equal to 8% under a closing pressure of 86 MPa.</p> |
