Abstract: Abstract The productivity characteristics of perforated gas well is investigated for the first time under real conditions considering drilling damage, perforation compacted zone and anisotropy in this paper. A nonlinear finite element model for non-Darcy flow in perforated gas reservoir is built to consider the effects of twelve factors on productivity ratio (PR) of perforated gas well. The nomographs for two cases are presented in this paper. Compared wit…
