Ceramic proppant fracturing and quartz sand contrast

In the fracturing process, the choice of what kind of frac proppant  is particularly important, ceramic proppant and fracturing ordinary quartz sand in the process What are the differences and similarities.
Currently the commonly used ceramic proppant fracturing of ordinary quartz sand and ceramic proppants ordinary  frac sand  is relatively inexpensive, but the strength is not high, the ceramic has a high strength   Proppant    available at a deeper formation fracturing higher conductivity, but the price is more expensive. Ordinary quartz sand and  Ceramic proppant  biggest drawback is under formation conditions will occur in broken, broken particles in the fracturing fluid flowback or oil and gas production will occur during migration, plug flow channel, so reducing fracture conductivity or in the fracturing fluid flowback phenomenon occurred during the sand spit.
Natural sand is quartz sand, high-quality quartz sand are often ancient aeolian dune, handling and screening of the wind sinking into the main mineral component of coarse quartz. Features: low intensity; applicable conditions: in shallow depth of less than 2000m. Namely ceramic sintering bauxite, alumina minerals, silicates and iron - titanium oxides. Features: high strength (56 ~ 105MPa), high density; applicable conditions: the more deep.
