Fracturing Evaluation for Sulige Gas Wells

On the theory base of the reservoir fluid mechanics and oil reservoir engineering,through studying fracturing evaluation of low permeability gas reservoirs,practical analysis theory and calculation method were established,which can provide base parameters for fracturing evaluation.On the basis of the studies,with the technical economics principles,a new concept,economic limit stimulation ratio was put forward.And economic analysis method to appraise the fracturing effect was investigated in the low-permeability fractured gas reservoir.
