| 摘 要： | 在分析单独利用小波变换或沃尔什变换进行测井曲线自动分层所存在的优势及弊端的基础上，依据沃尔什方法能适用多测井曲线分层和小波方法更能表征信号突变点的特点，提出了一种小波变换和沃尔什变换联合的测井曲线自动分层方法，该方法能有效地结合两者在测井曲线分层巾的优势并弥补各自的不足。实际测井资料的处理结果表明，与小波变换分层方法和沃尔什变换分层方法相比，该联合方法简单、快速、有效，更适合实际测井资料的处理。 |

| Abstract: | The advantages and disadvantages of wavelet transform or Walsh transform for automatic segmentation of well logs were discussed respectively. FAte to the ability of Walsh transforen to proess, multiple well logs and wavelet transform to detect signal singularity well, a method for joint application of the wavelet transform and Walsh transform for automatic segmentation of well logs was proposed. It maintains the desirable features of wavelet transform and Walsh transform method and can improve the accuracy. Its simplicity, rapidity and efficiency are demonstrated clearly by the results of processing practical well-log data. Compared with the two segmentation method, the joint method is more suitable for processing practical well-log data. |
| Keywords: | wavelet transform Walsh transform joint segmentation well logs |
