摘　　要：哈得逊油田薄砂层油藏是一个油层超深、超薄的层状边水砂岩油藏,采用双台阶水平井注水开发,目前进入中含水采油期,层间、平面矛盾已经凸显,需要开展以水平井为主的加密调整。本文结合该油藏水平井注水前缘测试资料,基于油藏工程和数值模拟工具,开展了水平井井筒摩擦阻力对产能的影响、不同水平段长度对应的泄油面积研究以及平行交错注采井网条件下数模指标的预测分析,论证了哈得逊油田薄砂层油藏水平井开发单台阶水平段的合理长度,为该油藏下步加密调整中水平井的优化设计提供了依据。Ha Dexun oilfied is a ultra-deep and ultra-thin layering sand reservoir with edge water,which is developed using double bench horizontal well and enters middle water-cut phase.The contradiction in and between layers are presented,so it is necessary to infill horizontal well and study the reasonable horizontal well length.Based on production profile test and injection frontier detection,using reservoir engineering and numerical simulation techniques,this paper systematically studied the wellbore friction influence on productivity,drainage area for different horizontal length,and the simulation index forecast for horizontal interlace well pattern.The reasonable horizontal length of single bench for Ha Dexun oilfield is elaborated,which can provide great guidance for the horizontal well design in the next infill adjustment.
