分形介质与分形地层FRACTAL MEDIA AND FRACTAL STRATIGRAPHY
李春峰
摘要(Abstract)：
由于地层的二元特征,对地层和地下介质有两种不同的认识倾向,即旋回性(准周期性)和随机性。实际的地下介质物性参数的变化以及地层的分布在一般意义上更具有分形和多重分形的特征,而准周期性和随机性只是其中的两种特别情况。与之类似,地层的过渡也不应该是简单的阶梯函数,而应该是由更具有一般意义的启动函数来描述。通过分析一套实际的多重分形碳酸盐岩沉积层序并对其可能指示的古环境和古海平面的变化进行了初步探讨。
关键词(KeyWords)： 分形;多重分形;地下介质;地层;碳酸盐岩沉积;古环境;海平面
