Research on Calculating Productivity of Multilateral Horizontal Gas Well with Wellbore Pressure Drop
According to the characteristics of multilateral horizontal well, by using pressure superposition and mirror image reflection theory, the mathematical model of steady percolation for multilateral horizontal well in bottom water drive gas reservoir is developed on the basis of a three-dimensional pseudo-pressure distribution model for horizontal gas wells. The wellbore model is formulated in consideration of friction loss and acceleration loss. After a case study with couple models, the effect of wellbore pressure drop on productivity of multilateral horizontal gas well is analyzed.
