LES测井评价系统

LES Log Evaluation System.

李文湘．ＬＥＳ测井评价系统．测井技术，１９９４．１８（１）：４４～５４ＬＥＳ测井评价系统由三部分组成：多矿物分析程序，合成测井曲线程序和测井相分析程序。ＬＥＳ系统能够处理包括地球化学测井在内的多种测井资料，适应于各种岩性剖面。它可提供矿物含量剖面和井相剖面，计算孔隙度、含水饱和度和渗透率等地层参数。操作简单、计算速度快，在实际应用中取得了很好的地质效果和经济效益。

og Evaluation System (LES) is composed of three main programs: Mineral Analysisprogram (MVA),;Log Data Synthesis program (SYDA) and Log Factes Analysis program(LOFA).LES is able to process various logging data including geochemical logging data and applicable to various lithology profiles. It can provide mineral volume profile, log facics profile and calculate parameters such as porosity, water saturation and Permeability etc. LES iseasy to operate and fast in calculation. It has got good geological results and obvious economic efficiency.
