Based on the analysis of seepage mechanism of fracturing wells in low permeability reservoir, this paper
establishes the capacity model of the vertical fractured well production under the factors of Start-up pressure gradient,
pressure sensitive effect and the artificial fracture length. The numerical simulation is compiled and software calculates
the capacity model by using numerical simulation. This simulation technique verifies the validity of the model and
numerical method. On this basis, we study the influence of the included angle of artificial fracture and well array
direction, artificial fracture length, start-up pressure gradient and production pressure difference to the capacity of the oil
well.
