Viscoelastic surfactant fracturing fluid

To reduce the fracturing process proppant sand manufacturers  eservoir and propped fracture injury , developed a viscoelastic surfactant fracturing fluids and using a capillary rheometer test equipment, the performance of fracturing fluid were Research . Laboratory evaluation results show that the ceramic proppants under conditions of 100 ℃ and 170s-1 , and after 1h shear viscosity in 130mPa · s or more ; 120 ℃ under the conditions of 170s-1 and , after 1h shear viscosity of 50mPa · s or more ; with the extension of the shearing time , a small change in viscosity of the fracturing fluid ; with decreasing temperature , the viscosity of the fracturing fluid has good recovery . The test results show that the high viscosity fracturing fluid and low cost , formation damage fracturing fluid lower than about 50 %. Field test confirmed that friction viscoelastic surfactant fracturing fluid equivalent to 25 % to 30% water friction , and friction is lower than the fracturing fluid 1MPa/1000m, 2口fracture stimulation of oil wells 5600t. Use the fracturing liquid fracturing , can effectively reduce the fracturing fluid to the reservoir and propped fracture damage, while improving the well stimulation effect . 

Structure performance of the proppant

Structure performance of the natural gas fracking  Proppant for a certain particle size and size distribution of natural sand probable high strength ceramic particles. Ceramsite branch 

Support agent with aluminum bauxite as raw material, through the powder granulating, sintering, with high temperature resistant, resistant to high Pressure, corrosion resistance, high strength, high conductivity, low density, breakage etc, to use The most widely. In the sand and ceramsite surface coating resin, to further improve the proppant sand manufacturers  Degree and diversion performance.

After the extraction of oil

proppant sand manufacturers and fracturing proppant wells over time, high-low permeability deposit after closing pressure fracturing treatment, the rock cracked petroleum, oil and gas from the cracks in the channel formed by the pooled out. Ceramic proppant material along with high-pressure solution is filled into the formation of cracks in the rock, the play not because of stress release propped fracture and closed, thereby maintaining high conductivity, so that the oil and gas flow, increase production. Ceramic proppant is widely used in the exploitation of oil and gas, to increase oil and gas production, and does not support the ground subsidence

Petroleum proppant ( ceramic sand )

Grains of sand proppant has a Hydraulic Fracturing Proppants temperature , high pressure , corrosion resistance, high strength, high conductivity , low density, low breakage rate and other characteristics, mainly for deep low-permeability reservoirs , currently the most widely used at home and abroad . By species classification can be divided into: high sand proppant ---- no pressure consolidation strength , consolidation fast, good permeability, low density ; fracturing proppant ---- Anti spit back a high pressure consolidation strength , crushing low permeability, low density ; coated proppant ---- remarkable resilience and long-term use at proppant sand manufacturers temperatures below 232 ℃ formation ; quartz sand proppant ---- acid low solubility for fracturing and acidizing support , a higher sphericity and conductivity . Divided by the anti- crushing strength : 52Mpa (7500psi), 69Mpa (10000psi), 86Mpa (12500psi) three series. Divided by the volume density : low density, medium density, high density

Divided according to specifications :12- 20 mesh ,16- 20 mesh ,16- 30 mesh ,20- 40 mesh ,30- 50 mesh ,40- 60 mesh ,40- 70 mesh ,70- 100 mesh , etc. , in order to meet domestic to meet the needs of domestic and international oil and gas wells , ITC company is vigorously developed, developing other different intensity and different specifications for customers to choose.
