西北某荒漠区的油气化探和遥感调查综合研究发现：（1）根据遥感图像解释的12个环形影像以色调异常为主．影纹结构异常欢之，其影像特征多为浅黄、桔黄、紫红色调。（2）7号环形影像（R7）及其周缘的化探与地物波谱联测数据因子分析和聚类分析表明，R7实质上是一个烃蚀变异常，1995年位于R7附近的一口参数并打出了工业油气流。（3）统计表明，多数环形影像异常内的C2、C3、C2、△C、Hg等指标的平均值高干区域背景值。（4）各环与R7（标准环）的秩相似指数分析表明，与R7相似程度最接近的是R8，其次为R9、R3、R4、R1、R6、R12。以上环形影像异常很可能是油气蚀变所致，因此值得重视。
A comprehensive study of petroleum geochemical exploration and remote sensing survey in a desert area in the northwest China found that: (1) The 12 ring images interpreted based on remote sensing images are dominated by abnormal hues. Shadowgraph abnormal structure of joy, the image features mostly light yellow, orange, purple hue. (2) The combination of geophysical and geophysical data from the 7th ring image (R7) and its periphery The data analysis and cluster analysis show that R7 is essentially a hydrocarbon alteration anomaly. In 1995, a parameter near R7 Played industrial oil and gas flow. (3) The statistics show that the average value of C2, C3, C2, △ C, Hg and other indicators in most annular image abnormalities is higher than the background value of dry areas. (4) The rank similarity index analysis of each ring and R7 (standard ring) shows that the closest to R7 is R8, followed by R9, R3, R4, R1, R6 and R12. The anomalies of the above ring images are likely to be caused by hydrocarbon alteration, so it is worth noting.
