摘　　要：多元素能谱测井通过全能谱分析方法求取单个地层元素的产额,进而求取元素重量百分含量和矿物百分含量,为识别复杂油气藏岩石类型和矿物类型、建立复杂油气藏新的测井解释模型及应用正确评价方法开辟了新的途径,为地质问题和工程问题的解决提供了新的手段.全能谱分析方法研究是当前国内核辐射测井研究热点之一.本文在分析多元素能谱测井的重要意义和研究现状的基础上,归纳总结了全能谱分析方法的研究现状、实现步骤、标准元素谱的获取方法、定量解析方法、元素百分含量和矿物含量求取方法,分析了全能谱分析方法中标准元素谱获取的难点和各种定量解析方法的优缺点.Using full spectrum analysis methods, Multi-element spectrum logging single element quantum is obtained and furtherly the element weight percent and formation mineral percent are calculated. The Logging breaks a new path to distinguish lithologies and mineral types of complicated oil and gas reservoirs for building their new interpretation models and applying reasonable evaluation methods. The Logging provides a new means for resolving geological problems and engineer problems. Full spectrum analysis methods are becoming one of the study hotspots in the China now. After analyzing the important significance and research status of multi-element spectrum logging, the paper summarizes the research status, analysis steps, gaining methods of standard element spectrums, quantitative analytic methods, the obtaining methods of element content and mineral content the characteristics, and analyzes the difficulties of standard element spectrum acquirement and the merits or demerits of quantitative analytic methods for full spectrum analysis methods. The analysis and summarization show that now in China, the research on full spectrum has been placed particular emphasis on quantitative analytic methods; there is not a real multi-element spectrum logging tool or a whole suit of standard spectrums including at least fine formation elements or a effective element-mineral interpretation model in use. It is necessary to strength basic research, instrument development and data-processing methods in full spectrum to realize Chinese multi-element logging.
