высокопрочный разрыва расклинивающий

The high-strength fracturing proppant is based on large quantity of Bauxite ,mixed with small part of chemical agent and phase transfer agent ,then refined ,graulation .the specification of particle range from 0.45mm to 0.90mm,from 0.09mmto 0.224mm ,which are sintered in the high temperature .under closed pressure ,high -strength fracturing proppant (GGcategory )has characteristics of higher strength ,lower breakage ,better sphericity and so on .currently ,this production is the best fracturing material for oil and gas wells in reforming formation . product index small round particles of the appearance size 0.45-0.90mm 97% sphericity >=0.80 bulk density g/cm3 1.50-1.80 acid solubility %<=5 usage Mainly used to support fractures with reforming formation in deep oil and gas wells increased permeability make oil and gas flow ,then increase the productivity
