摘　　要：水平井立体注采开发潜山类油藏是一种新型开采方式,其宏观渗流规律有待明确。采用数值模拟方法,对水平井注水位置、水平井注采方式和水平井段长度进行了优化研究。结果表明,底部注水开发效果优于顶部注水和对应位置注水,水平井交错注采开发效果优于叠置注采,考虑边界效应时,水平井段不宜过长。优化结果可指导油藏实际生产,同时为高效开发潜山类油藏提供了新的技术手段。Stereo injection and production to horizontal well in buried hill reservoirs is a new developing method,whose macro flow laws need to be definite.Based on numerical simulation method,the horizontal well flooding position,the horizontal well injection-production method and the horizontal segment length are optimized respectively.The results show that the development effect of bottom injection is better than the cases of top injection and corresponding position injection,that the development effect of horizontal well zigzag flooding is better than the case of over-below flooding,and that the horizontal segment length should not be too long with considering the border effect.The optimized results can be guidance for reservoir development.It can also provide a new technical mean for developing the buried hill reservoirs efficiently.
