摘要
阵列声波测井资料处理时窗宽的选择受多种因素的影响 ,选择固定窗宽处理不是一条最佳的途径。用STC(慢度 时间 )方法处理阵列声波测井资料时 ,时间窗的宽度 (简称窗宽 )对处理结果有比较大的影响。讨论了窗宽选择的理论依据 ,结合测井实际 ,分析了窗宽选择的复杂性 ;最后结合阵列声波测井资料 ,讨论了窗宽对时差处理结果的影响 ,提出了可变窗宽的处理思路 。
In the processing of array sonic logging waveforms, the selection of time window is effected by various factors. Processing array sonic logging waveforms with fixed time window is not a optimum way. The time window is also an important element when STC is used to process array sonic logging waveforms. The basis and method of selecting time window are discussed theoretically in this paper. Combined with actual array sonic logging data, analyzed are complexity of choosing window width and effects of window width. In the end, a new method with variable window widths is given.
