摘　　要：本文详细叙述了数量化理论Ⅰ(简易法)和数量化理论Ⅳ的具体做法及应注意的问题。数量化理论Ⅰ是将观测的样品,依据项目(特征变量)对基准变量(因变量:气井产量)进行预测;而数量化理论Ⅳ是在无基准变量的情况下,采用各气井的地质信息和井附近的地震信息对各井进行分型。在川南地区,采用这两种方法对二叠系阳新统38口已完钻井进行了油气预测及井位分类。其预测符合率,数量化理论Ⅰ为79％,数量化理论Ⅳ为87％,后者的分辨能力略高。但是,无论采用哪一种方法,其预测效果主要取决于对地质、地震因子的最佳拾取。This article details the usages of quantization theories Ⅰ and Ⅳ,and the matters needing attention. The quantization theory Ⅰ (simple method)is used to predict reference variable (dependent variable or gaswell production) from the terms (descriptive variable) of observation sample. Quantisation theory Ⅳ is used to class wells by analysing the geological informations of gas wells and the seismic informations nearby the gas wells when there is no reference variable. The two quantization theories were used to make hydrocarbon prediction and classification of 38 drilled wells which pexietrate Yangxin series of Permian system in south Sichuan. The prediction success rate of quantization theory Ⅰ is 79%, and that of quantization theory Ⅳ is 87%,the latter being higher than the former. However,no matter which quantization theory is used, the prediction effect mainly depends on the optimum pickup of geological and seismic factors.
