Hydraulic fracturing is oil and frac sand companies gas well

Hydraulic fracturing is oil and gas well production and injection Wells is an important technical measures of augmented injection, not only widely used in low permeability reservoirs, and in medium and high permeability reservoirs production stimulation and good results have been achieved. It is to use the ground high pressure pumps, absorptive capacity of the viscous fluid has considerably more than the bottom displacement in injection well, don't gas pressure at bottom hole, when the time pressure is greater than the wall near the ground stress and formation rock tensile strength, the cracks near the bottom bolt. Continue to inject with ceramic proppant manufacturers carrying fluid, crack extension forward and fill with ultra lightweight proppant, closed fracture closure on resin coated silica sand, thus formed in the near the bottom of the bottom has a certain geometry dimension and flow conductivity of sand filling cracks, make to increase attention of technological measures. The principle of hydraulic fracturing increase injection mainly reduced near the bottom hole formation fluid in the change of fluid seepage and seepage resistance of state, is the original radial flow change for reservoir and the one-way flow of approximation and cracks between the wellbore and one-way flow, eliminate the radial throttling losses, greatly reduces the energy consumption. Injection and oil gas well production or injection Wells will be greatly improved. If hydraulic fracture can unicom fracture reservoir of deep oil and gas layer and gas, the increase of the effect will be more obvious. In addition, the hydraulic fracturing team near the bottom of a well damage to remove oil and gas layer is jammed.
