摘　　要：石油测井面临的难题主要体现在数据传输和数据采集2个方面。随着测井仪器的日益成熟及测井数据精度要求的越来越高,数据传输误差大的难题也就越来越突出,而此前却一直未得到研究人员的重视。通过建立随机信号模型,将噪声和信号以相乘的形式引入,不仅使信噪比大大提高,还使总信号功率极大地得到提升,从一定程度上解决了测井中信号的误差问题。The problems of the petroleum logging mainly indwell in the data acqiusition and the data transmission.With the development of the technology in logging instrument,more and more precision logging data are acquired.At the same time,the errors are more evident and more evident in data transmission.By establishing the random signal model and introducing the noise and signal in the form of their product,signal-noise ratio has been raised apparently and total signal power has been promoted greatly.The problems of signal errors in logging have been resolved to a certain degree.
