摘　　要：吸水剖面资料反映的是注水井在某一压力下各单层的相对吸水能力和各层内吸水量的连续变化情况。分析吸水剖面可以了解油藏注入水的纵向分布和变化趋势,进而为后期油藏的深入开发提供依据[1,2]。通过对吸水剖面分布特征、小层吸水量分布特征等方面来对吸水剖面进行初步的探讨,了解层间非均质性对于注水开发效果的影响,并利用吸水剖面资料,运用洛伦兹曲线描述层间的非均质程度。该研究对于油藏今后的动态开发研究具有一定的指导意义。The profile log of water injection reflect the relative absorbing capacity of each single layer and the case of continuous changing in each layer of an injection well at a pressure. The analysis of profile log of water injection can understand the longitudinal distribution and change trend of the injected water in a reservoir so that the criteria are provided for further reservoir development in later stage. The profile log of water injection is elementally discussed to understand the impact of the interbed anisotropy on the effect of the flood development through the analysis of the distribution characteristics of the injection profile and the intake capacity of a layer. The interbed heterogeneous level is described by the Lorentz curve combining with the injection profiles. The research has certain guiding significance to the dynamic development of the reservoir in the future.
