The Intelligent Decision System Of The Digital Well-logging Data

In recent years, with the development of electric technology, the technology of litho logic formation is widely used in the project, litho logy varying with the depth, that is to say that it is one of the important purposes of scientific drilling of the continent to rebuild the rock station, it is important to achieve the purpose utilizing the well-logging materials. Auto-recognizing litho logic and determining litho logic boundary with the well-logging materials by computer have become the important direction of the technology of the well-logging development and the content of the well-logging worker researching. Because it cannot merely improve the speed of explaining, lightening and explaining personnel, and can utilize many kinds of mathematics and physics method to deal with the materials, thus improve the precision of explaining, offer more accurate, more reliable information for exploring and developing.Among many kinds of the methods about division of stratum, it is widely used that litho logy utilizing little trade extreme value of the well-logging curve .It can imitate the method used by the geologists, though its mathematics model is simple. For a long time, analyze worker divide into layer artificially according to log well shape of curve and the difference characteristic of around stratum. This primitive method is not adaptive with the quick development of the technology of explaining and the well- logging. Besides that it will cause the difference of the result by the different person and the different standards used. Though a lot of kinds of methods can be solved and explained a lot of problems in the work...
