摘　　要：统计分析表明塔里木中部地区奥陶系碳酸盐岩岩心裂缝与断裂具有良好的分形特征。裂缝分维值的大小首先受裂缝密度的控制 ,其次受裂缝分布特征的影响。断裂的分维值受断裂的发育程度及其形态的影响。The statistical data showed that the fissures and fracture systems in cores from the Ordovician carbonate rocks in the central Tarim area possessed a good property of fractal. The box counting dimension values of fissures were obviously controlled by fracture density, in addition, it was affected by fissure distributing characteristics. The development degree and its spatial distribution of fracture systems influenced the fault dimension values. The fractal dimension was an effective quantity parameter for describing fissure reservoir and fracture systems.
