It is necessary to record the linear scale before and after log and the time difference curve in the acoustic variable density log 摘要阐述了声波变密度测井时对其进行测前、测后线性刻度及记录时差曲线的必要性。
Experiments demonstrate that neoren algorithm yields accurate results for clusters with arbitrary shapes , variable sizes , variable densities and outliers 对典型数据的测试结果表明, neoren聚类算法能够发现任意形状、大小、密度的簇,对孤立点也很健壮。
The linear scale before and after log is an effective way to inspect the reality and accuracy of the log curves , such as downhole signal ' s amplitude limit or not and serious distortion , the variable density logging tool ' s signal linear amplification and working stability 测前、测后线性刻度对分析、判定变密度测井曲线的真实性与准确性体现在对井下波列的限幅与畸变程度、检测仪器的线性放大状态和稳定程度。
