摘　　要：由于碳酸盐岩具有非均质、裂缝性的特点,使得碳酸盐岩的油气检测更加困难。采用分形理论有可能为解决这类复杂问题带来曙光。描述分形的定量参数叫做分维(或分数维)。本文介绍了两种计算分维的方法:时间序列的分维计算和根据振幅谱计算分维。我们用这两种方法对四川丹凤场气田的一条联井剖面进行了计算,得到了满意的结果,它解答了原来多参数预测的遗留问题。我们认为分形理论在油气检测中的应用具有较大的潜力。The nonuniform and fractured properties of carbonate formation make carbonate reservoir prediction more difficult. The use of fractal theory causes it hopeful to solve such a complicated problem. The quantitative parameter that describes fractal is called fractal dimension. We recommend two fractal dimension calculation methods: fractal dimension calculation in time sereis and fractal dimension calculation using amplitude spectrum. The two methods were respectively used to make fractal dimension calculation of the seismic line which links some wells in Danfengchang gas field in Sichuan province. As a result, they brought satisfactory result and led to solving the tough problem which can not be solved in multiparameter prediction. We think fractal theory is potential in reservoir prediction.
