摘　　要：水平井射孔参数的优化对于水平井高效、稳定的生产有着重要的作用。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角。以水平井射孔完井产能预测模型和射孔后套管强度损失计算模型为理论基础,通过数值计算对水平井相关射孔参数进行了敏感性分析,利用正交试验方法在保证套管强度损失在安全生产允许范围内,对现场生产井常规射孔参数进行优选,使生产井能够在长期稳定生产前提下实现产能最大进行了综合评价,优选出最佳射孔参数组合。Perforation parameter optimization played an important role for efficient and stable horizontal well production.The perforation parameters were mainly included perforation density,wellbore diameter,perforation depth and perforation azimuth.On the theoretical basis of calculation model of producing energy of horizontal well completion and perforation productivity calculation model of strength loss after the perforation,the sensitivity was analyzed through numerical calculation on the related perforation parameter,thus to guarantee the casing strength loss was in the safety production by using the orthogonal experiment method to optimization the best perforation parameter combination,under stable production,wells are comprehensively evaluated for selecting the best perforation parameter.
