摘　　要：前人证实，地质裂缝具有分形性质，故本文利用分形插值原理对四川盆地L剖面进行了裂缝预测。分形插值是对复杂空间的一种逼近手段，它能更精细地描述处理对象。也就是说。只要通过一些已知点，即可插出具有分形性质的复杂图形。分形插位运算是在构造的选代函数系（IFS）中逐步进行的。在利用此法中，要尽可能将剖面上的所有的断层解释出来，以利于构造好的分形剖面。It has been shown that geological fractures have fractal characteristic. Fracture prediction of L section in Sichuan basin was made by doing fractal interpolation. The fractal interpolation is an approximating means for complicated space and describes detailedly the processed objects. In other words,a complicated graph of fractal characteristic can be plotted by doing interpolation along some known points. The operation of fractal interpolation is gradually performed in constructed iterativefunction system (IFS). The application of this method needs detailed fault interpretation in seismic section,which favours construction of a good fractal section.
