摘　　要：靖边油田小河区块主要开发层系为延安组延9,延长组长2、长6层,区域面积493 km2。其中,延长组长6属于典型的岩性油藏。由于该区域前期开发不科学,造成了目前采油井关停井较多,平面上注采井网不完善,纵向上注采对应率低,整体含水上升速度过快。本研究通过改善注水开发效果,精细认识该区域地质油藏信息,结合开发矛盾进行注水开发的系统化优化研究,以提高采油速度,最终提高油藏的采收率。The main development layers in Xiaohe Block of Jingbian Oilfield are Yanan Formation Yan9,Yanchang Formation Chang 2 and Chang 6,with an area of 493 km2. Among them,Chang 6 of Yanchang Formation belongs to typical lithologic reservoir. Due to the unscientific early development of this area,many production wells have been shut down at present,the injection-production well pattern on the plane is not perfect,the vertical injection-production correspondence rate is low,and the overall water cut rises too fast. In this study,by improving the water injection development effect,finely understanding the geological reservoir information in this area,and combining the development contradictions,a systematic optimization study of water injection development is carried out,so as to increase the oil recovery rate and ultimately improve the oil recovery rate of the reservoir.
