利用测井曲线的分数维分析火山岩地层的结构
首发时间:2007-05-10
摘要:区别不同结构的火山岩对于后续的油气储层评价、裂缝发育情况估计十分重要。本文通过对测井曲线分数维的提取来反映火山岩地层的结构,观察到结构比较复杂的火山碎屑岩的分数维普遍比结构比较简单的火山熔岩的大,所以可以用分数维的大小来反映火山岩地层的结构的复杂程度。

Analyzing the Structure of Igneous Formations with the Fractal Dimension of Logs
Abstract:It is very important to distinguish the different structures of igneous formations for subsequent estimation of reservoir and fracture development. In the paper, reflecting the structure of igneous formation by calculating fractal dimension of logs, the fractal dimension of pyroclastic is larger than lava is founded. Structure of pyroclastic is more complicated than that of lava, so reflecting the structure of igneous formation’s complexity with fractal dimension is feasible. So it is feasible to reflect the structure of igneous formation’s complexity with fractal dimension.
