1, Enhance permeability of stratum Circulate oil and increase output of oil . 2, In conformity with GB/T28001-2001 Standard.

The high –strength fracturing proppant (GD category)

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 ,granulation . the specification of particles range from 0.45mm to 0.90mm ,from 0.09mm to 0.224mm,which are sintered in the high temperature .under sealed pressure ,high-strength fracturing proppant (GD category) has characteristics of higher strength , lower breakage ,better sphericity and so on .currently ,this production is the best fracturing material for oil and gas well in reforming formation .
