Ceramsite proppant performance needs

At present, the domestic production of ceramic proppant is with bauxite as main raw material to prepare the products, acid resistance, crush resistance difference.

  The best performance of the blowing ceramsite propping breaking agent under the 69MPa rate was 2% ~ 4%, the acid solubility ranged from 3% to 5%, it is difficult to meet the Tahe oilfield fracturing and acidizing technology requirements.

  For Tahe reservoir UHP reservoir reformation of proppant, are high-grade production using alumina as main raw material,domestic products, temporarily unable to produce, mainly depends on the America imports, the price is quite expensive (about 7500 ~ 15000 yuan / ton, while the cost is less than half of this price).
