Ultra-high-density ultra-high-strength petroleum propping agent and preparation method thereof
The invention belongs to the technical field of petroleum propping agents and particularly discloses an ultra-high-density ultra-high-strength petroleum propping agent and a preparation method thereof. The ultra-high-density ultra-high-strength petroleum propping agent is prepared from, by mass, medium-grade bauxite 87-90%, Fe3O4 6-8% and pyrolusite 4-5%. The raw materials are taken in proportion, are jointly grinded into powder or are respectively grinded into powder and then are mixed, then spray granulation is performed, and sintering is performed at the temperature of 1400-1450 DEG C for at least 50 minutes to obtain a finished product. The ultra-high-density ultra-high-strength petroleum propping agent has the advantages that the medium-grade bauxite is wide in source, low in price and convenient to purchase; the petroleum propping agent uses black iron sheets produced during steel ingot forming in a high temperature furnace in the iron and steel industry, namely a surface oxide Fe3O4, as a special additive, is used in the industry for the first time, and waste is turned into wealth; the problems of raw material shortage and high cost in the preparation process of an existing ultra-high-density ultra-high-strength petroleum propping agent are solved.
