Finite element method has been used to study the flow characteristics of perforated wells and to investigate perforator penetration and damage mechanism in combination with core target experiments. Establishment of a finite element mathematical model for a core perforation and its numerical solution are presented in detail. The effect on productivity ratio and skin factor of depth of penetration, hole diameter, hole density, phase, format, damage depth, damage percentage, compaction zone depth, compaction perc entage, wellbore radius, drainage boundary radius, K_z/K_r ratio, bottom hole pressure, boundary pressure and production pressure difference is considered in the mathematical model. Grid sensitivity analysis ensures convergence and accuracy of calculation. An example is given to illustate the flow behavior of the core target, and the effect of perforating parameters on productivity ratio is analyzed. The table listed in API RP 43 is shown by calculation, electric modelling and core target experiment to be less reliable. Revision of these data will help evaluation of core flow efficiency. Compaction zone permeability can also be obtained by back calculation.
