ＬＥＳ程序能最大限度地利用各种测井资料获取孔隙度、饱和度、渗透率等各种地质参数，并可提供矿物含量剖面和测井相剖面。ＬＥＳ程序在大港油田张东地区等勘探新区的应用，解释符合率比以往处理方法得以提高，同时操作简便、计算速度快，已经取得了较好的经济效益和良好的地质效果。 The LES program can maximize the use of various logging data to obtain various geological parameters such as porosity, saturation, permeability, etc., and provide mineral content profiles and well log facies profiles. The application of LES program in the exploration area such as Zhangdong area of ​​Dagang Oilfield can explain that the coincidence rate is higher than previous treatment methods and the operation is simple and the calculation speed is fast. The LES program has achieved good economic benefits and good geological effects.
