Do you really know "Hydro Fracture " in crude oil exploitation


Hydraulic fracture is an important technical measure for stimulation of oil & gas well and water injection well. In the stimulation, it achieved significant achievements in the using low, medium and high permeability oil & gas reservoirs. Using high pressure pumps, it send the high viscosity fluids that exceed the displacement of absorption capacity in the wells. When The crack arise in the bottom near, when the pressure is higher than the wall near the ground stress and rock tensile strength. Then continue to inject the carrying fluid with the support agent. When the crack is filled with the support agent, the formation forms the san-filled cracks that have a certain size and conductivity in the down hole. That technical measure can make the well increase in production and injection
