摘　　要：镰刀湾油区位于伊陕大斜坡中部,油藏受岩性与构造的双重控制,平面油砂体分散,除了长213面积较大外,其它层多为不连续小砂体,纵向叠合较差,于2003年开始动用、2010年转注水开发,采用油藏工程方法对开发从注入、产出、见效、递减、含水等变化特征进行研究,深化了此类油藏开发特征的认识,为后期的综合治理改善开发效果提供了依据。The Liandaowan Oilfield is located in the middle of the Yishan slope.The reservoir distribution is controlled by lithology and structure.The planar oil sand bodies are dispersed.Most of the layers are discontinuous small sand bodies with poor longitudinal overlap except for the Chang 213 layer.The reservoir started to be developed in 2003 and switched to water injection development in 2010.The reservoir engineering method is used to study the development characteristics,deepening the understanding of the development characteristics of this type of reservoir,and providing a basis for comprehensive management to improve the development effect in the later period.
