Overview

     Fracturing is one of the main means of stimulation and reformation of low permeability reservoir in oil field production. The stimulating effect of fracturing operation is closely related to the diverting capacity of the supporting fractures, diverting capacity depends on the width of cracks and the permeability of proppant after the crack closed. Therefore, to ensure the best construction design, the proppant from different sources shoud be optimized and quality controlled before fracturing operation, fracture diverting capacity tester is just this type of testing device to do the optimization and quality control of all kinds of proppant in front of the fracturing operation.
