Film-coated sand and ceramic proppant

Coated sand: Generally, dry  Frac sand  coated with a liquid resin and catalyst, of a mixture of a phenolic resin, followed by high temperature heating and complete cure, so that the liquid resin is uniformly coated on the surface of the sand, the sand at the granulation process has played the role of the core and mold.
Coated sand control is a loose sandstone reservoir silt and fine control of new technologies, and its fine sandy silt control of oil and gas wells and the effect is very good. Coated sand control technique involves two qualities of fiber, with different functions. Add fiber resin coated sand, its strength has been greatly improved and extended its use expiration date.
As new developments proppant coated  ceramic proppant  continues to evolve, for different well conditions in underground geological conditions and become more specialized. Coating technology is also being constantly improved, so deeper underground proppant can withstand higher pressure and higher temperature environment needs are met.
In the proppant technology to silicon-based technology can improve the adherence of the resin to improve the strength  Proppant  to improve conductivity and anti-blocking properties.
