最优化方法是解决众多领域里最优设计的数学方法。本文讨论了最优化方法中改进的牛顿法的原理和它如何应用于测井资料解释中所建立的数学模型;用 FORTRANⅦ语言编制了相应的测井解释程序,处理了大港油田七口井的曲线,所得的解释结果有可喜的趋势。用最优化理论的其它一些方法处理测井资料的研究还在进行,待取得成果后,将再撰文讨论之。
The optimization approach is to solve mathematical problems in optimal design in many fields. This paper discusses the principle of the improved Newton method in the optimization method and how it is applied to the mathematic model established in the interpretation of log data. Corresponding log interpretation programs are compiled by FORTRAN Ⅶ language and the curves of seven wells in Dagang Oilfield are processed , The results of the interpretation of the results have a welcome trend. Research on logging data processed by other methods of optimization theory is still underway and will be discussed again after the results are achieved.
