號的準確識別對石油的勘探技術有著重大的意義。本文通過對測井信號的預處理，利用徑向基神經(jīng)網(wǎng)絡的一種延伸--概率神經(jīng)網(wǎng)絡，對測井信號進行網(wǎng)絡訓練，達到識別的效果。研究和實驗結果表明，本文方法對測井信號的識別有很高的準確性，實用性，運行速度快。

Abstract：As the oil demand increased year by year, oil exploration technology requirements are also getting higher and higher, so identify the exact signal for oil exploration technology has a great significance. Based on the logging signal preconditioning, Used a kind of RBF network extension—PNN to train the logging signal to attach the clustering effect. Research and experimental results show that this method of identification on logging signals has high accuracy, practicality, run faster.
