Hydraulic fracturing

When using ground hydraulic ceramic proppants technology is high-pressure pump , the viscous liquid absorption capacity greatly exceeds the underlying displacement injection wells, in the bottom suffocating pressure, when the pressure is greater than the near wellbore formation rock to stress and intensity of anti- inflation in the bottom near the bottom of cracks. To inject the liquid with sand carrying proppant fracture extends forwardly and filled with proppant in the fracture closure shut the proppant , thereby forming a certain geometry and conductivity in the vicinity of the bottom of the bottom sand filling cracks , resin coated sand proppant making wells to increase production , by injection purposes . Hydraulic fracture stimulation , by injection principle is near the bottom of the bottom of the formation and fluid penetration resistance of the fluid flow state , is the original radial flow throttling losses , greatly reducing the energy consumption, thus oil and gas wells production or injection wells will be greatly improved injection rate .
