Abstract:

Horizontal well is an important means of the recovery of fractured reservoir. In view of the seeping characteristics of the fractured reservoir and Permeability anisotropy reservoir, this Paper establishes a Percolation model of horizontal well，and obtains its solutions by finite Fourier transformation method. Besides，this Paper also draws the chart boards of dimensionless Pressure and dimensionless velocity. According to the law that dimensionless Pressure and dimensionless velocity vary with time and space，the Paper Presents the horizontal well seeping characteristics of the above two types of reservoir, favorable extension orientation of the horizontal segment of horizontal well and effective technological measures of increasing Production.
