摘　　要：通过优选地层参数 ,提出了视砂岩厚度、视有效厚度的概念 ,并描述了注水井分层注水层段的地质特征 .在此基础上 ,运用逐步回归分析方法 ,对注水层段的合理注水量进行拟合 ,定量描述了增注措施的有效性 ,为注水井增注措施选井 .选层和选择措施类型提供参考 ,实际应用效果良好 .Through selecting reservoir parameters, the concepts of visual sandstone thickness and visual effective thickness are presented, which can effectively describe the geological characteristics of separated-zone water injection interval. Based upon that, the injection interval's reasonable water injection rate is matched through applying the stepwise regression analysis, and the effectiveness of intensified injection is quantitatively described, which provides the references for the well selection, choice of layer and choice of measure types for injection measures of water wells. Good effects have been achieved after its application.
