FMI测井在火山岩岩性识别中的应用

The Application of FMI for Identifying the Lithology in Volcanic Formation

以准噶尔盆地西北缘二叠系火山岩为研究对象，利用FMI（Fullbore Formation Microlmager）测井技术，结合常规测井资料及钻井取心资料，在岩心刻度测井的基础上，总结了不同岩性的典型曲线特征，对研究区的复杂火山岩地层岩性进行了有效划分和识别，建立了岩性综合识别的标准。

The Permian volcanic rock in the northwest margin of Junggar Basin was used as the object of study based on FMI （Fullbore Formation Micro Imager） logging technology and combined with the data of conventional logging and coring in well drilling and as well as core calibration logging, the features of typical curves of different lithologic properties were summarized, the lithologic prop- erties of complex volcanic rocks in the study area were effectively identified. Based on the study, a criterion is established for an integrated identification of lithology.
