| 摘 要： | 测井曲线分层是物理勘探中的首要工作.论文在分析自然伽玛、自然电位、密度等多条曲线形态特征的基础上,提出了主成分分析、小波变换与综合方差比分析相结合的方法,完成了对多测井曲线的自动分层.针对非地层因素引起的数据干扰问题,加入了程序比较字符串的方式提取公共曲线,并归并薄层界面.实际结果表明,该方法兼顾了分层效率和分层精度的要求,具有较高的应用价值.

| Abstract: | Zoning by well-logging curves is the primary work in the physical exploration. Based on the morphological character of multiple well-logging curves such as GR, SP and DEN, a method with joint application of principal component a- nalysis, wavelet transform and comprehensive variance ratio for automatic zoning is proposed. In addition, the ways of com- paring the character string to pick up common curves and merging thin layers are adopted to weaken the data interference of non-formation factor. The actual results show that the method has a high application value, with efficiency and accuracy into account. |
