The main influencing factors of perforation completion on oil well productivity are hole density, hole diameter, hole depth and hole phase. The optimal design of perforation parameters based on the optimal oil well productivity is one of the key technologies to improve the productivity of perforated wells. Based on the semi-analytical model of perforated well productivity, the finite element analysis method was used to simulate the productivity of perforated well, and the numerical simulation results were analyzed according to the orthogonal experimental method. The results show that the productivity ratio increases with the increase of hole depth, and the slope is large when the hole depth is small. When the perforation depth exceeds the depth of drilling pollution zone, the inflection point of the curve occurs, and the slope becomes smaller and flattened. With the increase of hole diameter, the productivity ratio gets greater. Considering the problem of casing strength in the actual perforation process, the hole diameter should be taken as maximum as pos-sible under the condition of ensuring casing strength. The productivity ratio increases while the upward trend of productivity ratio decreases with the increase of pore density. With the increase of phase angle, the productivity ratio decreases. When the phase angle changes from 60° to 90°, the productivity increases greatly. The productivity has little change when the phase angle changes between 90° and 180°. The primary and secondary influencing factors are found by comparing the value of range R. This study provides guidance for the optimization of perforation parameters. [ABSTRACT FROM AUTHOR]
