The pressure drops in horizontal wellbores, acceleration, wall friction, perforation roughness, and fluid mixing are analyzed in a partially perforated wellbore. It was demonstrated that the perforation inflow actually reduced the total pressure drop. The pressure drop due to perforation roughness was eliminated by the perforation inflow when the ratio of radial perforation flow to axial pipe flow rate reached a certain limit. Three dimensional numerical simulations on a partially perforated pipe with 150 perforations, geometrically similar with wellbore casing (12 SPF, and 60 phasing) were presented and analyzed. Numerical simulations by commercial code CFX were also conducted with Reynolds numbers ranging from 28,773 to 90,153 and influx flow rate ranging from 0 to 899 lit/hr to observe the flow through perforated pipe, measure pressure drops, friction factors and pressure loss coefficients. The acceleration pressure drop might be important compared with the frictional pressure drop. The numerically calculated results using k-ε model were compared with the experimental results. The numerical solutions agreed well with the experimental data.
