摘要
从分形理论和统计物理学的角度介绍了地震道分维和熵的计算方法，并利用实际地震资料进行了计算．结果表明：地震道含油气和不含油气时的关联维与熵有明显的差异；地震道的关联维和熵有很好的相关性；熵的计算比较简单。在根据地震资料作油气检测时用熵作为含油气指标之一比用关联维更合适．
The fractal dimension and the entropy of field seismic data are computed respectively on the basis of on fractal and statistic physics. The results show that the fractal dimension of seismic traces when oil/gas exsists is significantly different from that when oil/gas do not. that the fractal dimension is definitely relative to the entropy, and the entropy is easier to compute than the fractal dimension. The entropy is more suitable as one of the indicators of oil/gas existence than the fractal dimension.
