Oil well fracturing proppant

Oil well Fracturing proppant is a ceramic particle product with high fracture strength, mainly used for oil well supported in order to increase oil and gas production, an environmentally friendly product. Oil well proppant of various raw materials using high bauxite, sintered ceramics, natural silica sand, glass beads, metal balls, low intensity proppant substitute for oil and gas production with good results.

Oil and gas deep mining, the high closure pressure low permeability deposits by fracturing treatment, the rock cracked hydrocarbon, oil and gas from the cracks formed in the channel pooling out. Well along with the use of ceramic proppant into the formation hyperbaric solution filling fissures in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that gas flow, increase production. Practice has proved that using oil well  frac proppant  fracturing wells can increase production by 30-50%, but also to extend the service life of oil and gas wells.

Oil well fracturing proppant their quality is different, the effect is not the same. Shale, flowers and other ultra-lightweight ceramic mainly used for decoration, concrete and other industries; dense, low broken rate ceramic mainly used in petroleum industry, as a Proppant used.

1  ceramic pressure into the ground to ground softened, reducing the formation pressure, help the oil to be pumped to the surface;

2  After the oil is pumped, leaving gap formation, ceramic leaving them as a filler, does not cause ground subsidence.
