Matching of Resolution in Frequency Domain for Well Logging Signals.

Zhou Yuantian.  
Analysis of signal frequency domain brings to light the frequency characteristicof well logging signals.It is discovered that log signals with different resolutionhave different amplitude spectrum and/or power spectrum.And frequency structureof logging signals has been built by fitting method.By means of frequency modulation for logging signals with different resolution,their resolution has been matched.Finally,through Fourier inverse transform, logs with improved resolution are obtained.
