摘　　要：八面河油田北一区为复杂小断块边水油藏,主要含油层系为沙三段和沙四段。纵向上,沙三段储层物性好,沙四段储层薄、物性差,造成储量动用不均。针对纵向上动用程度差异大问题,建议采取对油藏实施整体研究及分段治理的的原则。沙三段主要是充分利用现有老井,实施措施挖潜;沙四段主要是重新落实构造、储层再认识与开采特征相结合制定相应调整对策,选择配套工艺,部署工作量及实施。通过上述分段治理,有效提升了区块产量,提高了整体动用程度。Area 1 in northern Bamianhe Oilfield is an edge-water reservoir trapped in complex small fault block .Its main oil-bearing series are Sha-3 Member and Sha-4 Member .In vertical ,Es3 reservoir physical property is bet‐ter while Es4 reservoir is thinner ,leading to unevenness of reserve utilization .Therefore ,total research should be done on the edge-water reservoir and the principle of section-by-section development should be adopted .In Es3 , it is necessary to take full use of existing maturing wells to realize measure discovering potentials .In Es4 ,it is essen‐tial to adopt relevant adjustment measures ,select matching technology and deploy workload and put it into effect .
