Hydraulic fracturing ceramic proppant applications

Hydraulic fracturing  Ceramic proppant  in low-permeability oil and gas wells on the hydraulic fracturing process used to key materials, can improve the level of oil and gas diversion.
Hydraulic fracturing is a ceramic support sintered bauxite and other additives, mineral composition is alumina, silicates and iron - titanium oxides. Its multi-cylindrical spherical, high strength, high closing pressure for deep oil and gas layer fracturing, for the deep, in order to improve the conductivity is also commonly used to make trailing proppant. In the hydraulic fracturing process, first the fracturing fluid and additives are mixed together, and then pumped into the formation, cracks, and to bring to the seam  Proppant ，  proppant flowback after the crack opening. In a construction corresponding cost ratio is usually: pumping fluid accounted for 46%, 25% proppant fracturing chemicals accounted for 19%, 10% acid.
Throughout the hydraulic fracturing process can be divided into the following steps: well and layer selection, fracturing design, construction preparation, fracturing, flowback. Fracturing process is actually not that long, generally require two hours.
hydraulic fracturing is the role of ceramic proppant in the fracture after cracks open, so its strength is critical proppant must be sufficient to withstand the closure pressure.
