测井曲线标准化方法对比研究及应用
|
摘要
测井资料的准确性不仅影响地下介质岩性特征的分析,同时也是三维地震测井约束反演技术中的核心和基础。为了能更好的根据测井资料得到真实的地质信息,尽可能的减小非地质因素带来的影响,利用频率直方图法,趋势面法,基于希尔伯特变换的方法对测井曲线分别进行了标准化,并将三种方法进行比对,得出应根据不同的地质构造条件选用不同的标准化方法:标准层发育稳定,且埋深差异较小,可选择频率直方图法;标准层虽全区发育稳定,但埋深垂向分布差异较大,且标准层的物性特征随着埋深的变化有明显的规律性,可选择趋势面法;若标准层受构造影响明显,且埋深在垂向分布上差异较大时,可采用基于希尔伯特变换的方法。另外,可以使用不同的标准化方法相互验证,以便得到更好的效果。
The well logging information's accuracy does not only influence the analysis of lithologic characteristics of the underground mediums,but it is also the core and basis of the constrained inversion in 3D seismic.In order to acquire the factual geological information by taking better advantage of the well logging information,to decrease the influence generated by the non-geological factors as much as possible,it is especially important to correct the well logging.This paper utilizes the regular methods of the frequency histogram analysis,the trend surface analysis and the method based on Hilbert transformation to standardize the logging curves,and then contrast these methods,draw a conclusion that chose appropriate method according to different geological conditions.In addition,all of methods can be used at the same time and mutual authentication,in this way,logging standardization will get better result.
