摘　　要：本文探索用基于概率论和数理统计的蒙特卡罗(Monte carlo)方法来替换相关对比法。根据地层倾角测井曲线的具体问题,建立了同时评价多道曲线相关性的迭加矢量概率模型,然后采用随机试验方法对该模型求解。由于蒙特卡罗方法同时评价4条倾角测井曲线的相关性,故可有效地克服周波跳跃,更好的压制各道曲线的随机干扰,并在处理前就能对曲线的信噪比作出评估。Liu Zhengping,Du Fengping,Peng Cuncang.Diplog Processing with Monte Carlo Technique.WLT, 1993;17(3):183～189 Monte Carlo technique which is based on propability theory and mathematical statistics is used to replace correlation technique.A stacked-vector propability model is set up to correlate four dip logs simultaneously, and then random test is made to solve the model.Since Monte Carlo technique can correlate four dip logs simultaneously,it can successfully overcome cycle skipping,suppress random noise and estimate signal to noise ratio before processing.
