Abstract
The present invention discloses a super strength haydite supporting agent and a preparation method thereof. The super strength haydite supporting agent comprises components of the following proportion by weight: 10 to 30% of bauxite, 50 to 70% of alumyte, 8 to 15% of high iron bauxite, 7 to 20% of clay soil, 2 to 5% of manganese minerals, 0.5 to 2.5% of potassium feldspar and 0.1 to 1.2% of starch gums. The mineral components of the proportion are respectively milled into fine sieved powder, mixed and stirred harmoniously, and then the fine powder is atomized by water vapor and rolled into balls in a granulator; the super strength haydite supporting agent is prepared by adding the starch gums, rotating and sieving through high temperature sintering in a tunnel kiln after the addition of the atomizing water vapor is stopped. According to tests, a product of the supporting agent has the advantages for having high crushing capacity, effectively supporting fracturing cracks, greatly improving permeability in the cracks, making the circulation of oil gas smooth and enhancing the rate of oil production.
