摘要
在岩性复杂的变质岩地区实施的大陆科学钻探,是通过采集井下不同深度岩石物理化学性质和物理场的各种数据,研究地壳特征及演化过程的各种科学问题。利用测井资料达到岩性剖面的重建是大陆科学钻探的重要目的之一。文章利用沃尔什变换对钻孔岩性剖面进行分层,大重建的岩性剖面结果可以看出,该方法对于变质岩地区不同岩性的划分还是比较有效的。
The reconstruction of lithological profile is one of the important aims in Continental Scientific Drilling. In metamorphic rock area, it is very important to get this point by making use of logging data. This paper made use of the Walsh transform to identify the rock boundaries, and provided a new and effective method to identify the different kinds of lithologies in metamorphic rock area from the results of the reconstructed lithological profile.
