作为新兴的测井仪器，岩性扫描测井（LithoScanner）通过获取地层元素含量，进一步获得地层矿物含量，帮助地质学家解决复杂岩性识别等地质学难题。为了充分推广其在地质学领域的应用， 笔者等对岩性扫描测井的原理和解释处理流程进行梳理，并对应用过程中出现的典型案例进行分析。LithoScanner测井可直接获取地层岩性特征，帮助识别地层界面，并实现页岩等复杂岩性、岩相的准确识别。而脆性矿物含量、有机碳含量等也可被LithoScanner测井准确获取，从而计算地层中的脆性指数和有机碳的含量。LithoScanner测井可以探测黄铁矿、煤层等特殊矿物组分，因此可以辅助核磁共振测井资料解释评价。最后指出LithoScanner测井与相应的岩芯和实验数据进行比对，提高LithoScanner测井的可靠性。研究有助于将LithoScanner测井中蕴含的大量地质信息进行挖掘与解读，并消除该资料应用中的一些误区，从而推广LithoScanner测井应用领域。
As a new well logging technology, LithoScanner logs can further obtain the content of minerals in the formation, which can help geologists solve geological problems such as complex lithology identification by obtaining the content of elements in the formation. To fully promote the application of LithoScanner logs in the geological field, this paper reviews the principle and interpretation processing flow of LithoScanner logs and analyzes typical application cases. LithoScanner logs can directly obtain lithology characteristics in the formation, and help identify the formation interface, and lithology and lithofacies in the shale. In addition, brittle mineral content and organic carbon content can be accurately obtained by LithoScanner logging, to calculate the brittleness index and organic carbon content in the formation. LithoScanner logs can detect the components of specific minerals such as pyrite and coal seams, thus assisting in the interpretation and evaluation of NMR logging data. Finally, it is pointed out that LithoScanner logging can be compared with corresponding cores and experimental data to improve the reliability of LithoScanner logs. This paper helps dig dive on and interpret a large amount of geological information contained in LithoScanner logs and eliminates some misunderstandings in applying this data.
