摘要
本文论述了伽玛测井反褶积-差值迭代法,它首先用反褶积三点式含量作为迭代初值,然后用三点式构造含量修正公式,使得迭代过程的收敛速度得到了加快。同时也介绍了反褶积-差位迭代法的收敛速度参数α_0的取位规则;分析了各类迭代法的解释效果和使用特点。模型钻孔与实际钻孔的资料解释结果表明:反褶积-差值迭代法,是一种较好的分层解释方法。
This paper states the deconvolution-difference iteration technique for Gamma-ray logs.It first 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 determing the deconvolution-difference iterative speed parameter is discussed in the paper.The in- terpretation effects and characteristicns from Various iteration technique are also analysed.The inter- pretation results of the materials from model and production drill holes show:the deconvolution-differ- ence iteration technique is a good subdivision interpretation method.
