The deconvolution-difference iteration technique for gamma-ray logs

This paper states the deconvolution-difference iteration technique for gamma-ray logs. The author takes the deconvolution-difference three-point content as initial iteration value. Then the formula is adjusted by three-point tectonic content. The iterative speed in iterative process is accelerated. The rule determining the deconvolution-difference iterative speed parameter is discussed. The interpretation effects and characterisatios from various iteration technique are also analysed. The interpretation results of the materials from model and production drill holes show that: the deconvolution-difference iteration technique is a good subdivision interpretation method
