灰色关联法识别地层岩性应用研究

Application of Gray Correlation Method in the Recognition of Formation Lithology

利用常规测井资料方法识别陆相沉积形成的复杂砂泥岩剖面有一定难度,针对此问题提出一种基于灰色关联的岩性识别方法。在吐哈温米油田wj3-1井测井资料的基础上,通过取芯井岩心和相应测井曲线对应特征的分析,提取反映岩性的特征参数,应用灰色关联分析方法对取心井的岩性进行识别。

It is difficult to recognize complex sand-shale profile with conventional methods. A method for recognizing lithology based on gray relation is presented. On the basis of the logging data of the wj3-1 well,it analyzes the characteristic between the core of cored well and logging curve,extracts some characteristic lithology parameters,and uses gray relation analysis to recognize the lithology of the cored well.
