摘　　要：射孔参数主要包括射孔密度、孔眼直径、孔眼深度和射孔相位。从理论模型入手,对可能的射孔方案用有限元方法进行产能预测,对各个方案满足目标和约束条件的情况做优化评价,从中找出最优射孔参数,使所选择的射孔参数能够达到最大产能比,且套管和油层的损害最小。Perforating parameters mainly include perforation density,perforation diameter, depth and perforation phase so on.From theoretical models,productivity forecast is given to possible perforation project by finite element method,and optimized evaluation is also given to conditions which every project meets target and binding condition,and the most optimized perforating parameters are found from these to get the highest productivity ratio,and the lest damage to casing and oil layer at the same time is done.

关 键 词：优化设计 射孔 密度 深度 相位
