摘　　要：杨家坝油田是一个具有天然裂缝和人造裂缝的低渗透双重砂岩油藏,裂缝的存在严重的影响了开发效果。根据岩心资料和测井资料,运用数理统计和分形几何的方法,对裂缝的发育、分布和分形特征进行定性评价,认为研究区主要发育沿纹层分布的水平缝,裂缝的发育受岩性、厚度以及构造影响明显。Yangjiaba Oilfield was a low permeability and sandstone reservoir with natural and artificial fractures. The effect of production was influenced by the fractures. Based on the data of cores and well logging, statistics and fractal methods are used for a qualitative evaluation on fracture growth, distribution and fractal property. It is considered that in the studied area horizontal fractures are mainly developed along laminar distribution, the growth of fractures is obviously influenced by lithology and thickness.
