摘要(Abstract)：

针对现有裂缝模型多采用均质或拟均质假设处理方法,不能反映实际复杂裂缝结构,引入分形几何的方法描述裂缝网络,推导分形裂缝储层的渗透率公式.基于底水油气藏双重不完善井的复杂渗流模式,即直井射孔段上部为水平径向流,射孔段下部为半球形向心流,将其推广到水平井,认为水平井以上为半椭球流,水平井以下为半圆柱形向轴心流,分别推导裂缝型底水气藏直井和水平井产能公式.应用结果表明:裂缝和生产井与气水界面的距离对产能的影响为缝宽分形维数越大,直井和水平井产能越大;气藏打开程度越大,直井产能越大;水平井距底水越远,水平井产能越小.

关键词(KeyWords)：分形;裂缝;底水气藏;产能
