Hydraulic fracturing fracturing effect depends on the length of validity of the quality of the proppant

In hydraulic fracturing in fracturing effect the success or failure depends primarily on the length of validity of the quality of the proppant. Ceramic proppant role is to produce hydraulic fracture fracture filling, making it no longer re-closed and form a flow channel having a high conductivity. In the reservoir characteristics and fracture geometry the same conditions, fractured wells increased yield and production performance depends on the conductivity of cracks. Fracture conductivity refers to a fracture conductivity (transport) capacity reservoir fluids, and to crack proppant permeability (Kf) layer and the support crack slit width (Wf) of the product [KW] f to represent.

 Generally believed that the type of proppant, physical properties (size, strength, ball roundness, density, etc.) and their distribution in the fracture of (laid concentrations that support the dosage unit fracture area), as well as crack closure Stress is a major factor controlling fracture conductivity. Therefore, the master Ceramic proppants physical properties and fracture conductivity and many other factors, there is a reasonable choice in favor of proppant fracturing favor fracturing fluid and material support agents made more precise requirements. Type from the proppant, physical properties and evaluation methods proppants fracture conductivity and its influencing factors, and selection of proppant four face proppant and fracture flow capacity to make a presentation.
