| titleOfInvention | Ceramsite propping agent composition and ceramsite propping agent and its preparation method and application |
| abstract | The present invention discloses a kind of ceramsite propping agent composition, and wherein, said composition contains bauxite, manganese oxide, magnesia, iron oxide and sinter additives. The present invention also discloses a kind of preparation method of ceramsite propping agent, and the method comprises: above-mentioned ceramsite propping agent composition is contacted with water, and carry out granulation and sintering. The present invention's ceramsite propping agent that also openly said method makes and the application in oil well gas well fracturing thereof. In the present invention, by the synergy of each component in described composition, can obtain and under the clossing pressure of 86MPa, there is the percentage of damage that is less than 3%, and there is the apparent density that is greater than 3.3g/cm3 and the volume density that is greater than 2.5g/cm3, be suitable for use in oil well gas well fracturing, there is the highdensity ceramsite propping agent of superhigh intensity of good spherical shape. |
