| 摘 要： | 尽管测井数据具有良好的连续性和高分辨率特性,地质科研中对测井曲线和地层层序的研究仍以观察实践为主.沉积旋回的复杂性和相对一致性、测井曲线的连续性和非周期性以及小波变换的多分辨率和时频域兼顾的特性,这三者相互联系、相互对应,构成了小波变换用于测井数据层序划分的理论基础.以四川孝泉区须家河组某井为例,对该井地质数据进行了连续小波变换,并将该组段划分为3个层序和18个准层序. |
| 关 键 词： | 测井数据 小波变换 层序 准层序 |

| Abstract: | The primary research methods in geology remain based on observation and experience. However, the logging data are of fine continuity and high resolution. The theoretical foundation of stratigraphic sequence identification consists of the complexity and relative consistency of sedimentary cycles, the continuous and nonperiodic characteristics of logging curves, and the multi-resolution and time- analysis characteristics of the wavelet transform. The Xujiahe logging data with the highest resolution and best continuity has been divided into three stratigraphic sequences and eighteen subsequences as a case study. |
| Keywords: | logging data wavelet transform stratigraphic sequence subsequence |
