Abstract

Abstract:

The seepage field of horizontal wells can be divided into outer region, which is a radial flow to an ellipse vertical well, and inner one, which is an ellipsoid flow to horizontal well. Each seepage model is deduced considering fluid compressibility and stress sensitivity, and then the formula for the performance of horizontal well is gained by utilizing conformal transformation and equivalent flow resistance law. Compared with classic formula, the derived formula is reasonable and reliable. When considering fluid compressibility and stress sensitivity, it means when α is not equal to zero, there is no longer a linear relationship between conduction of horizontal well and the drawdown pressure; the production will decrease with the increasing of CK and increase with the increasing of Cρ . When stress sensitivity is strong, it increases slowly with the increasing of drawdown pressure.
