Method of Geomechanical Parameter Determination and Volumetric Fracturing Factor Simulation under Highly Stochastic Geologic Conditions

In order to accurately predict geomechanical parameters of oil-bearing reservoirs and influencing factors volumetric fracturing, a new method parameter prediction combining seismic inversion, well logging interpretation production data is proposed in this paper. Herein, we present structure model, petrophysical model model. Moreover, three-dimensional typical reservoir was established corrected using history matching. On basis, established, 11 volume fracturing including formation were analyzed their impact ranked, the oil recovery rate accumulated before after optimal compared. The results show that with respect parameters, thickness main factor; interlayer stress difference are secondary factors; permeability, Young’s modulus Poisson’s ratio weak factors. For pilot reservoir, optimized fracture increased by 7 tons/day relative traditional fracturing. After one year production, 4 showing great potential similar reservoirs.
